| * ARM: 7403/1: tls: remove covert channel via TPIDRURWWill Deacon2012-04-281-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | TPIDRURW is a user read/write register forming part of the group of thread registers in more recent versions of the ARM architecture (~v6+). Currently, the kernel does not touch this register, which allows tasks to communicate covertly by reading and writing to the register without context-switching affecting its contents. This patch clears TPIDRURW when TPIDRURO is updated via the set_tls macro, which is called directly from __switch_to. Since the current behaviour makes the register useless to userspace as far as thread pointers are concerned, simply clearing the register (rather than saving and restoring it) will not cause any problems to userspace.

| * ARM: 7399/1: vfp: move user vfp state save/restore code out of signal.cWill Deacon2012-04-231-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | The user VFP state must be preserved (subject to ucontext modifications) across invocation of a signal handler and this is currently handled by vfp_{preserve,restore}_context in signal.c Since this code requires intimate low-level knowledge of the VFP state, this patch moves it into vfpmodule.c.

For now on it's limited to the DT-enabled boards but we can compile all the core together. - The Kconfig series is stacked before other patches as it is simple and non-intrusive. Its goal is to remove too restrictive dependencies on SoC names. This will allow to add support for newer SoC seamlessly. - Some very "cosmetic" Kconfig changes are also added (entry names, comments, etc.). * tag 'at91-3.5-cleanup' of git://github.com/at91linux/linux-at91: (19 commits) ARM: at91: add defconfig for device tree ARM: at91/dt: do not specify the board any more ARN: at91: introduce SOC_AT91xxx define to allow to compile SoC core support ARM: at91: add SOC_AT91SAM9 kconfig option to factorise select ARM: at91: pm select memory controler at runtime ARM: at91: move at91_init_leds to board init ARM: at91: do not pin mux the UARTs in init_early ARM: at91: drop at91_set_serial_console ARM: at91: uncompress: autodetect the uart to use ARM: at91: uncompress Store UART address in a variable hwrng: Kconfig: remove dependency for atmel-rng driver Input: Kconfig: remove dependency for atmel_tsadcc driver rtc: Kconfig: remove dependency for AT91 rtc driver ARM: at91/Kconfig: website link for AT91SAM9G20-EK ARM: at91/Kconfig: add AT91SAM9x5 family to AT91_EARLY_DBGU0 entry ARM: at91/Kconfig: add clarifications to AT91SAM9M10G45-EK entry ARM: at91/Kconfig: add comment to at91sam9x5 family entry ARM: at91/Kconfig: change at91sam9g45 entry ARM: at91: change AT91 Kconfig entry comment Also updates the cleanup branch to v3.4-rc3.

* | ARM: fix __io macro for PCMCIARob Herring2012-04-051-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With commit c334bc1 (ARM: make mach/io.h include optional), PCMCIA was broken. PCMCIA depends on __io() returning a valid i/o address, and most ARM platforms require IO_SPACE_LIMIT be set to 0xffffffff for PCMCIA. This needs a better fix with a fixed i/o address mapping, but for now we just restore things to the previous behavior. This fixes at91, omap1, pxa and sa11xx. pxa needs io.h if PCI is enabled, but PCMCIA is not. sa11xx already has IO_SPACE_LIMIT set to 0xffffffff, so it doesn't need an io.h.

We follow this later with a flush_cache_all() after all static memory mappings have been initialized, which ensures that this is safe from any cache effects.

I've built all the working defconfigs from all the arches that I can and made sure that they don't break. The reason for these patches is that I recently encountered a circular dependency problem that came about when I produced some patches to optimise get_order() by rewriting it to use ilog2(). This uses bitops - and on the SH arch asm/bitops.h drags in asm-generic/get_order.h by a circuituous route involving asm/system.h. The main difficulty seems to be asm/system.h. It holds a number of low level bits with no/few dependencies that are commonly used (eg. memory barriers) and a number of bits with more dependencies that aren't used in many places (eg. switch_to()). These patches break asm/system.h up into the following core pieces: (1) asm/barrier.h Move memory barriers here. This already done for MIPS and Alpha. (2) asm/switch_to.h Move switch_to() and related stuff here. (3) asm/exec.h Move arch_align_stack() here. Other process execution related bits could perhaps go here from asm/processor.h. (4) asm/cmpxchg.h Move xchg() and cmpxchg() here as they're full word atomic ops and frequently used by atomic_xchg() and atomic_cmpxchg(). (5) asm/bug.h Move die() and related bits. (6) asm/auxvec.h Move AT_VECTOR_SIZE_ARCH here. Other arch headers are created as needed on a per-arch basis." Fixed up some conflicts from other header file cleanups and moving code around that has happened in the meantime, so David's testing is somewhat weakened by that.

Essentially: - as we no longer support any other Acorn platforms other than RiscPC anymore, we can collect all that code into mach-rpc. - convert Acorn expansion card stuff to use IRQ allocation functions, and get rid of NO_IRQ from there. - cleanups to the ebsa110 platform to move some private stuff out of its header files. - large amount of SA11x0 updates: - conversion of private DMA implementation to DMA engine support (this actually gives us greater flexibility in drivers over the old API.) - re-worked ucb1x00 updates - convert to genirq, remove sa11x0 dependencies, fix various minor issues - move platform specific sa11x0 framebuffer data into platform files in arch/arm instead of keeping this in the driver itself - update sa11x0 IrDA driver for DMA engine, and allow it to use DMA for SIR transmissions as well as FIR - rework sa1111 support for genirq, and irq allocation - fix sa1111 IRQ support so it works again - use sparse IRQ support After this, I have one more pull request remaining from my current set, which I think is going to be the most problematical as it generates 8 conflicts." Fixed up the trivial conflict in arch/arm/mach-rpc/Makefile as per Russell. * 'platforms' of git://git.linaro.org/people/rmk/linux-arm: (125 commits) ARM: 7343/1: sa11x0: convert to sparse IRQ ARM: 7342/2: sa1100: prepare for sparse irq conversion ARM: 7341/1: input: prepare jornada720 keyboard and ts for sa11x0 sparse irq ARM: 7340/1: rtc: sa1100: include mach/irqs.h instead of asm/irq.h ARM: sa11x0: remove unused DMA controller definitions ARM: sa11x0: remove old SoC private DMA driver USB: sa1111: add hcd .reset method USB: sa1111: add OHCI shutdown methods USB: sa1111: reorganize ohci-sa1111.c USB: sa1111: get rid of nasty printk(KERN_DEBUG "%s: ...", __FILE__) USB: sa1111: sparse and checkpatch cleanups ARM: sa11x0: don't static map sa1111 ARM: sa1111: use dev_err() rather than printk() ARM: sa1111: cleanup sub-device registration and unregistration ARM: sa1111: only setup DMA for DMA capable devices ARM: sa1111: register sa1111 devices with dmabounce in bus notifier ARM: sa1111: move USB interface register definitions to ohci-sa1111.c ARM: sa1111: move PCMCIA interface register definitions to sa1111_generic.c ARM: sa1111: move PS/2 interface register definitions to sa1111p2.c ARM: sa1111: delete unused physical GPIO register definitions ...
