| * ARM: Rename ARCH_SHMOBILE to ARCH_SHMOBILE_LEGACYLaurent Pinchart2013-12-101-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | SH-Mobile platforms are transitioning from non-multiplatform to multiplatform kernel. A new ARCH_SHMOBILE_MULTI configuration symbol has been created to group all multiplatform-enabled SH-Mobile SoCs. The existing ARCH_SHMOBILE configuration symbol groups SoCs that haven't been converted yet. This arrangement works fine for the arch/ code, but lots of drivers needed on both ARCH_SHMOBILE and ARCH_SHMOBILE_MULTI depend on ARCH_SHMOBILE only. In order to avoid changing them, rename ARCH_SHMOBILE to ARCH_SHMOBILE_LEGACY, and create a new boolean ARCH_SHMOBILE configuration symbol that is selected by both ARCH_SHMOBILE_LEGACY and ARCH_SHMOBILE_MULTI.

* | stackprotector: Introduce CONFIG_CC_STACKPROTECTOR_STRONGKees Cook2013-12-201-0/+14
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This changes the stack protector config option into a choice of "None", "Regular", and "Strong": CONFIG_CC_STACKPROTECTOR_NONE CONFIG_CC_STACKPROTECTOR_REGULAR CONFIG_CC_STACKPROTECTOR_STRONG "Regular" means the old CONFIG_CC_STACKPROTECTOR=y option. "Strong" is a new mode introduced by this patch. With "Strong" the kernel is built with -fstack-protector-strong (available in gcc 4.9 and later). This option increases the coverage of the stack protector without the heavy performance hit of -fstack-protector-all. For reference, the stack protector options available in gcc are: -fstack-protector-all: Adds the stack-canary saving prefix and stack-canary checking suffix to _all_ function entry and exit. Results in substantial use of stack space for saving the canary for deep stack users (e.g. historically xfs), and measurable (though shockingly still low) performance hit due to all the saving/checking. Really not suitable for sane systems, and was entirely removed as an option from the kernel many years ago. -fstack-protector: Adds the canary save/check to functions that define an 8 (--param=ssp-buffer-size=N, N=8 by default) or more byte local char array. Traditionally, stack overflows happened with string-based manipulations, so this was a way to find those functions. Very few total functions actually get the canary; no measurable performance or size overhead. -fstack-protector-strong Adds the canary for a wider set of functions, since it's not just those with strings that have ultimately been vulnerable to stack-busting. With this superset, more functions end up with a canary, but it still remains small compared to all functions with only a small change in performance. Based on the original design document, a function gets the canary when it contains any of: - local variable's address used as part of the right hand side of an assignment or function argument - local variable is an array (or union containing an array), regardless of array type or length - uses register local variables https://docs.google.com/a/google.com/document/d/1xXBH6rRZue4f296vGt9YQcuLVQHeE516stHwt8M9xyU Find below a comparison of "size" and "objdump" output when built with gcc-4.9 in three configurations: - defconfig 11430641 kernel text size 36110 function bodies - defconfig + CONFIG_CC_STACKPROTECTOR_REGULAR 11468490 kernel text size (+0.33%) 1015 of 36110 functions are stack-protected (2.81%) - defconfig + CONFIG_CC_STACKPROTECTOR_STRONG via this patch 11692790 kernel text size (+2.24%) 7401 of 36110 functions are stack-protected (20.5%) With -strong, ARM's compressed boot code now triggers stack protection, so a static guard was added. Since this is only used during decompression and was never used before, the exposure here is very small. Once it switches to the full kernel, the stack guard is back to normal. Chrome OS has been using -fstack-protector-strong for its kernel builds for the last 8 months with no problems.

BE8 (modern big endian) changes for ARM from Ben Dooks 2. big.Little support from Nicolas Pitre and Dave Martin 3. support for LPAE systems with all system memory above 4GB 4. Perf updates from Will Deacon 5. Additional prefetching and other performance improvements from Will. 6. Neon-optimised AES implementation fro Ard. 7. A number of smaller fixes scattered around the place. There is a rather horrid merge conflict in tools/perf - I was never notified of the conflict because it originally occurred between Will's tree and other stuff. Consequently I have a resolution which Will forwarded me, which I'll forward on immediately after sending this mail. The other notable thing is I'm expecting some build breakage in the crypto stuff on ARM only with Ard's AES patches. These were merged into a stable git branch which others had already pulled, so there's little I can do about this. The problem is caused because these patches have a dependency on some code in the crypto git tree - I tried requesting a branch I can pull to resolve these, and all I got each time from the crypto people was "we'll revert our patches then" which would only make things worse since I still don't have the dependent patches. I've no idea what's going on there or how to resolve that, and since I can't split these patches from the rest of this pull request, I'm rather stuck with pushing this as-is or reverting Ard's patches. Since it should "come out in the wash" I've left them in - the only build problems they seem to cause at the moment are with randconfigs, and since it's a new feature anyway. However, if by -rc1 the dependencies aren't in, I think it'd be best to revert Ard's patches" I resolved the perf conflict roughly as per the patch sent by Russell, but there may be some differences. Any errors are likely mine.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If we are booting in LE and compiled for BE8, then add code to set the state to bE8. Since the instruction stream is always LE, we do not need to do anything special to the instruction. Also ensure that the secondary processors are started in the same mode. Note, we do add about 20 bytes to the kernel image, but it seems easier to do this than adding another configuration to change.

* | ARM: delete mach-sharkLinus Walleij2013-09-173-404/+0
|/ | | | | | | | | | | | | | | | | | | | | The Shark machine sub-architecture (also known as DNARD, the DIGITAL Network Appliance Reference Design) lacks a maintainer able to apply and test patches to modernize the architecture. It is suspected that the current kernel, while it compiles, does not even boot on this machine. The listed maintainer has expressed that he will not be able to spend any time on the maintenance for the coming year. So let's delete it from the kernel for now. It can always be resurrected with git revert if maintenance is resumed. As the VIA82c505 PCI adapter was only used by this architecture, that gets deleted too.

In the case of a system which can handle more than 4GB, the memory node cell size is 4: each data (memory size and memory address) are 64 bits and then use 2 cells. The current code in atags_to_fdt.c made the assumption of a cell size of 2 (one cell for the memory size and one cell for the memory address), this leads to an improper write of the data and ends with a boot hang. This patch writes the memory size and the memory address on the memory node in the device tree depending of the size of the memory node (32 bits or 64 bits).

Also noteworthy is the work on PCI here, which is traditionally part of the SoC specific code. With the changes done by Thomas Petazzoni, we can now more easily have PCI host controller drivers as loadable modules and keep them separate from the platform code in drivers/pci/host.

Apparently, this was supposed to emit the message "Warning: This coprocessor register access is deprecated in ARMv8" when using certain mcr/mrc instructions and building for ARMv8. Unfortunately, the message that is actually emitted appears to be '(null)', which is less helpful in comparison. Even more unfortunately, this is biting us on every single kernel build with a new gas, because arch/arm/boot/compressed/head.S and some other files in that directory are built with -march=all since kernel commit 80cec14a8 "[ARM] Add -march=all to assembly file build in arch/arm/boot/compressed" back in v2.6.28. This patch reverts Russell's nice solution and instead marks the head.S file to be built for armv7-a, which fortunately lets us build all instructions in that file without warnings even on the broken binutils. Without this patch, building anything results in: arch/arm/boot/compressed/head.S: Assembler messages: arch/arm/boot/compressed/head.S:565: Warning: (null) arch/arm/boot/compressed/head.S:676: Warning: (null) arch/arm/boot/compressed/head.S:698: Warning: (null) arch/arm/boot/compressed/head.S:722: Warning: (null) arch/arm/boot/compressed/head.S:726: Warning: (null) arch/arm/boot/compressed/head.S:957: Warning: (null) arch/arm/boot/compressed/head.S:996: Warning: (null) arch/arm/boot/compressed/head.S:997: Warning: (null) arch/arm/boot/compressed/head.S:1027: Warning: (null) arch/arm/boot/compressed/head.S:1035: Warning: (null) arch/arm/boot/compressed/head.S:1046: Warning: (null) arch/arm/boot/compressed/head.S:1060: Warning: (null) arch/arm/boot/compressed/head.S:1092: Warning: (null) arch/arm/boot/compressed/head.S:1094: Warning: (null) arch/arm/boot/compressed/head.S:1095: Warning: (null) arch/arm/boot/compressed/head.S:1102: Warning: (null) arch/arm/boot/compressed/head.S:1134: Warning: (null) Signed-off-by: Arnd Bergmann <arnd@arndb.de> Cc: stable@vger.kernel.org Cc: Matthew Gretton-Dann <matthew.gretton-dann@arm.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

* ARM: 7672/1: uncompress debug support for multiplatform buildShawn Guo2013-03-152-0/+15
| | | | | | | | | | | | | | | | | | | | | Instead of giving zero support of uncompress debug for multiplatform build, the patch turns uncompress debug into one part of DEBUG_LL support. When DEBUG_LL is turned on for a particular platform, uncompress debug works too for that platform. OMAP and Tegra are exceptions here. OMAP low-level debug code places data in the .data section, and that is not allowed in decompressor. And Tegra code has reference to variable that's unavailable in decompressor but only in kernel. That's why Kconfig symbol DEBUG_UNCOMPRESS controlling multiplatform uncompress debug support is defined with !DEBUG_OMAP2PLUS_UART && !DEBUG_TEGRA_UART. It creates arch/arm/boot/compressed/debug.S with CONFIG_DEBUG_LL_INCLUDE included there, implements a generic putc() using those macros, which will be built when DEBUG_UNCOMPRESS is defined.

| | | | | | | | | | | | | | | | | | | | | | | | | | | decompressor Before jumping to (position independent) C-code from the decompressor's assembler world we set-up the C environment. This setup currently does not set r9, which for arm-none-uclinux-uclibceabi toolchains is by default expected to be the PIC offset base register (IE should point to the beginning of the GOT). Currently, therefore, in order to build working kernels that use the decompressor it is necessary to use an arm-linux-gnueabi toolchain, or similar. uClinux toolchains cause a prefetch abort to occur at the beginning of the decompress_kernel function. This patch allows uClinux toolchains to build bootable zImages by forcing the -mno-single-pic-base option, which ensures that the location of the GOT is re-derived each time it is required, and r9 becomes free for use as a general purpose register. This has a small (4% in instruction terms) advantage over the alternative of setting r9 to point to the GOT before calling into the C-world.

This is useful for the C decompressor implementations used for unpacking compressed kernels. This patch disables alignment faults and enables the v6 unaligned access model on CPUs which support these features (i.e., v6 and later), allowing full unaligned access support for C code in the decompressor. The decompressor C code must not be built to assume that unaligned access works if support for v5 or older platforms is included in the kernel. For correct code generation, C decompressor code must always use the get_unaligned and put_unaligned accessors when dealing with unaligned pointers, regardless of this patch.

It's the introduction of the first multiplatform support on ARM, and with this (and the later branch) merged, it is now possible to build one kernel that contains support for highbank, vexpress, mvebu, socfpga, and picoxcell. More platforms will be convered over in the next few releases. Two critical last things had to be done for this to be practical and possible: * Today each platform has its own include directory under mach-<mach>/include/mach/*, and traditionally that is where a lot of driver/platform shared definitions have gone, such as platform data structures. They now need to move out to a common location instead, and this branch moves a large number of those out to include/linux/platform_data. * Each platform used to list the device trees to compile for its boards in mach-<mach>/Makefile.boot. Both of the above changes will mean that there are some merge conflicts to come (and some to resolve here). It's a one-time move and once it settles in, we should be good for quite a while.

However, it will not be useful for any real work, because it relies on a number of useful things to be disabled for now: * SMP support must be turned off because of conflicting symbols. Marc Zyngier has proposed a solution by adding a new SOC operations structure to hold indirect function pointers for these, but that work is currently stalled * We turn on SPARSE_IRQ unconditionally, which is not supported on most platforms. Each of them is currently in a different state, but most are being worked on. * A common clock framework is in place since v3.4 but not yet being used. Work on this is on its way. * DEBUG_LL for early debugging is currently disabled. * THUMB2_KERNEL does not work with allyesconfig because the kernel gets too big [Rob Herring]: Rebased to not be dependent on the mass mach header rename. As a result, omap2plus, imx, mxs and ux500 are not converted. Highbank, picoxcell, mvebu, and socfpga are converted.

| * | | ARM: zImage/virt: hyp mode entry support for the zImage loaderDave Martin2012-09-193-8/+73
| | |/ | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The zImage loader needs to turn on the MMU in order to take advantage of caching while decompressing the zImage. Running this in hyp mode would require the LPAE pagetable format to be supported; to avoid this complexity, this patch switches out of hyp mode, and returns back to hyp mode just before booting the kernel. This implementation assumes that the Hyp mode view of memory and the PL1 view of memory are coherent, providing that the MMU and caches are off in both, as required by the boot protocol. The zImage decompression code must drain the write buffer on completion anyway, and entry into Hyp mode should flush any prefetch buffer, avoiding hazards associated with local write buffers and the pipeline.

|/ | | | | | | | | | | | | | | | | | | When enabling the MMU for ARMv7 CPUs, the decompressor does not touch the ttbcr register, assuming that it will be zeroed (N == 0, EAE == 0). Given that only EAE is defined as 0 for non-secure copies of the register (and a bootloader such as kexec may leave it set to 1 anyway), we should ensure that we reset the register ourselves before turning on the MMU. This patch zeroes TTBCR.EAE and TTBCR.N prior to enabling the MMU for ARMv7 cores in the decompressor, configuring us exclusively for 32-bit translation tables via TTBR0.

* ARM: 7437/1: zImage: Allow DTB command line concatenation with ATAG_CMDLINEGenoud Richard2012-07-091-2/+60
| | | | | | | | | | | | | | | | | | | | | This patch allows the ATAG_CMDLINE provided by the bootloader to be concatenated to the bootargs property of the device tree. This is useful to merge static values defined in the device tree with the boot loader's (possibly) more dynamic values, such as startup reasons and more. The bootloader should use the device tree to pass those values to the kernel, but that's not always simple (old bootloader or very small one). The behaviour is the same as the one introduced by Victor Boivie in 4394c1244249198c6b85093d46935b761b36ae05 by extending the CONFIG_CMDLINE.

These have never been extremely popular and have fallen into disuse over time with no active maintainer taking care of them. The u5500 soc never made it into a product, so we are removing it from the ux500 platform.
