| * ARM: 6006/1: ARM: Use the correct NOP size in memmove for Thumb-2 kernel buildsCatalin Marinas2010-03-291-2/+2
| | | | | | | | | | | | | | | | | | | | When compiling the kernel to Thumb-2, using a 16-bit NOP in the memmove() implementation causes the preceding ADD PC instruction to branch incorrectly in the middle of a 32-bit LDR or STR instruction. The memmove() code is now similar to the memcpy() template. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
| * ARM: 6005/1: arm: kprobes: fix register corruption with jprobesMika Westerberg2010-03-291-1/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current implementation of jprobes allocates empty pt_regs from the stack which is then passed to kprobe_handler() and eventually to singlestep(). Now when instruction being simulated is STMFD (like in normal function prologues without CONFIG_FRAME_POINTER), stores using SP actually write over top of the fabricated pt_regs structure. This can be reproduced for example by using LKDTM module: # modprobe lkdtm # mount -t debugfs none /sys/kernel/debug # echo PANIC > /sys/kernel/debug/provoke-crash/INT_HW_IRQ_EN after this, it fails with corrupted registers (before the requested crash would occur): lkdtm: Crash point INT_HW_IRQ_EN of type PANIC hit, trigger in 9 rounds lkdtm: Crash point INT_HW_IRQ_EN of type PANIC hit, trigger in 8 rounds Internal error: Oops - undefined instruction: 0 [#1] last sysfs file: /sys/devices/platform/serial8250.0/sleep_timeout Modules linked in: lkdtm CPU: 0 Not tainted (2.6.34-rc2 #69) PC is at irq_desc+0x1638/0xeeb0 LR is at 0x25 pc : [<c050b428>] lr : [<00000025>] psr: c80a0013 sp : ce94bd60 ip : c050b3e8 fp : a0000013 r10: c0aa453c r9 : cf5d4000 r8 : ce9a1822 r7 : c050b424 r6 : 00000025 r5 : c039d8f8 r4 : c050b3e8 r3 : 00000001 r2 : cf4d0440 r1 : c039d8f8 r0 : 00000020 Flags: NZcv IRQs on FIQs on Mode SVC_32 ISA ARM Segment user Control: 10c5387d Table: 8e804019 DAC: 00000015 Process sh (pid: 496, stack limit = 0xce94a2e8) Stack: (0xce94bd60 to 0xce94c000) [...] Code: 000002cd 00000000 00000000 00000001 (dead4ead) ---[ end trace 2b46d5f2b682f370 ]--- Kernel panic - not syncing: Fatal exception in interrupt This patch allocates enough space (2 * sizeof(struct pt_regs)) from the stack to prevent such corruption.

| * ARM: 5996/1: ARM: Change the mandatory barriers implementation (4/4)Catalin Marinas2010-03-252-6/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The mandatory barriers (mb, rmb, wmb) are used even on uniprocessor systems for things like ordering Normal Non-cacheable memory accesses with DMA transfer (via Device memory writes). The current implementation uses dmb() for mb() and friends but this is not sufficient. The DMB only ensures the relative ordering of the observability of accesses by other processors or devices acting as masters. In case of DMA transfers started by writes to device memory, the relative ordering is not ensured because accesses to slave ports of a device are not considered observable by the DMB definition. A DSB is required for the data to reach the main memory (even if mapped as Normal Non-cacheable) before the device receives the notification to begin the transfer. Furthermore, some L2 cache controllers (like L2x0 or PL310) buffer stores to Normal Non-cacheable memory and this would need to be drained with the outer_sync() function call. The patch also allows platforms to define their own mandatory barriers implementation by selecting CONFIG_ARCH_HAS_BARRIERS and providing a mach/barriers.h file. Note that the SMP barriers are unchanged (being DMBs as before) since they are only guaranteed to work with Normal Cacheable memory.

* | include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo2010-03-30103-36/+71
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The function locomo_m62332_senddata sends a three byte i2c message to a M62332 DAC. This entire function is guarded with a spin_lock_irqsave at the start of the function and a spin_unlock_irqrestore at the end. As each byte is transferred, the i2c ACK from the DAC is checked. Currently, if the ACK is missing the function simply returns without the unlock. It also leaves the i2c bus in an invalid state since the last byte transferred did not have a "stop" condition and leave the bus idle. Fix this by adding an exit path using goto.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The locomo spi registers are all defined in locomo.h as offsets from the first spi register LOCOMO_SPI (0x60), which is itself an offset from the locomo base address. To correctly access these registers LOCOMO_SPI must always be included in the address calculation. There are two places in locomo.c where this is not done. The first one, in locomo_suspend, actually results in a write to LOCOMO_ST instead of LOCOMO_SPICT. The second is in __locomo_probe and results in a write to LOCOMO_MCSX2 instead of LOCOMO_SPIIE. Fix these by including LOCOMO_SPI in the calculation. Signed-off-by: H Hartley Sweeten <hsweeten@visionengravers.com> Signed-off-by: Eric Miao <eric.y.miao@gmail.com>

| * OMAP4: fix temporary hacks that break multi-omap PMKevin Hilman2010-03-111-7/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When building for multi-omap, and OMAP4 is enabled, CONFIG_ARCH_OMAP4 will be true and prevent included code from building/running for OMAP2/3 as well. This problem exists in io.c where some hwmod/PM/SDRC init code is prevented from running even on OMAP2/3 when OMAP4 is included in a multi-OMAP build. A quick glance suggests that this #ifndef is no longer needed in most of the cases. In the remaining cases, the function is wrapped with "if (cpu_is_omap24xx() || cpu_is_omap34xx())" which will be optimized out for OMAP4-only builds. Note that this is only a short-term fix. Longer-term, OMAP4 needs to create init functions for SDRC and hwmod late-init.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently if omap2420 is defined but not omap2430, cpu_is_omap2430() is still defined as a macro, instead of #define'd to zero. This results in conditional cpu_is_omap2430() code still being compiled, and leads to possible compile/link errors. In particular for hwmod init. To fix, add extra #ifdefs to CPU check macros to ensure that the is_omap* macros are zero for each OMAP2 if they are not configured into the kernel.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch follows the commit be093beb608edf821b45fe00a8a080fb5c6ed4af by Russell King: OMAP wishes to pass state to the boot loader upon reboot in order to instruct it whether to wait for USB-based reflashing or not. There is already a facility to do this via the reboot() syscall, except we ignore the string passed to machine_restart(). The patch adds the missing parameter to omap1_arch_reset() and omap_prcm_arch_reset(), and modifies the latter to pass the reboot command parameter to the boot loader instead of reboot mode (which is for kernel internal use only and cannot be modified by the userspace).

Only omap4430 and omap3630 have 4 uarts at the moment. This patch reduces the number of uarts when cpu is not omap4430 or omap3630.

As discussed at: http://thread.gmane.org/gmane.linux.usb.general/27432/focus=4460 Otherwise we'll get errors like: drivers/usb/core/hcd.c:1892: error: 'pm_wq' undeclared (first use in this function) drivers/usb/core/hcd.c:1892: error: (Each undeclared identifier is reported only once drivers/usb/core/hcd.c:1892: error: for each function it appears in.)

| * omap2: Update n8x0 defconfig to test multi-omap and DMA api changesTony Lindgren2010-03-111-18/+142
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Recent DMA API changes broke compile for tusb6010. While testing the fixes for tusb6010, I had to update the n8x0 defconfig quite a bit. Might as well merge it while at it to make it more usable as we're using this to test the multi-omap booting between V6 and V7 ARMs. Also, anybody using n8x0 with a current kernel will most likely want to mount root on the MMC instead of the onenand to keep the Maemo install intact. Enable I2C, REGULATOR, MMC, MFD, PM, and USB. Also change the root to /dev/mmcblk0p2 instead of the onenand. Signed-off-by: Tony Lindgren <tony@atomide.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | the early_param() call in board-omap3touchbook.c expands to: static const char __setup_str_early_touchbook_revision[] __section(.init.rodata) _aligned(1) = tbr; [...] and we have a non-const variable being added to the same section: static struct ehci_hcd_omap_platform_data ehci_pdata __section(.init.rodata); because of that, gcc generates a section type conflict which can (and actually should) be avoided by marking const every variable marked with __initconst.
