2012-05-14ARM: spear6xx: remove board selection optionsArnd Bergmann
There are no board specific configurations that need user intervention, so just make MACH_SPEAR600 the silent default for ARCH_SPEAR6XX to prevent users from turning it off, which would result in a build error.

Each irq_chip for the main interrupt controller has offsets set for irq masking registers, which added to respective base results in a pointer to appropriate hardware register. However this is not correct for INTC_CONTROL as there is only one INTC_CONTROL register. This does not cause problems because generic ack code is never called, but remove this assignment to avoid confusion.

2012-04-28ARM: 7406/1: hotplug: copy the affinity mask when forcefully migrating IRQsWill Deacon
When a CPU is hotplugged off, we migrate any IRQs currently affine to it away and onto another online CPU by calling the irq_set_affinity function of the relevant interrupt controller chip. This function returns either IRQ_SET_MASK_OK or IRQ_SET_MASK_OK_NOCOPY, to indicate whether irq_data.affinity was updated. If we are forcefully migrating an interrupt (because the affinity mask no longer identifies any online CPUs) then we should update the IRQ affinity mask to reflect the new CPU set. Failure to do so can potentially leave /proc/irq/n/smp_affinity identifying only offline CPUs, which may confuse userspace IRQ balancing daemons. This patch updates migrate_one_irq to copy the affinity mask when the interrupt chip returns IRQ_SET_MASK_OK after forcefully changing the affinity of an interrupt.

2012-04-28ARM: 7405/1: kexec: call platform_cpu_kill on the killer rather than the victimWill Deacon
When performing a kexec on an SMP system, the secondary cores are stopped by calling machine_shutdown(), which in turn issues IPIs to offline the other CPUs. Unfortunately, this isn't enough to reboot the cores into a new kernel (since they are just executing a cpu_relax loop somewhere in memory) so we make use of platform_cpu_kill, part of the CPU hotplug implementation, to place the cores somewhere safe. This function expects to be called on the killing CPU for each core that it takes out. This patch moves the platform_cpu_kill callback out of the IPI handler and into smp_send_stop, therefore ensuring that it executes on the killing CPU rather than on the victim, matching what the hotplug code requires.

2012-04-28ARM: 7403/1: tls: remove covert channel via TPIDRURWWill Deacon
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.

2012-04-27ARM: PXA2xx: MFP: fix potential direction bugIgor Grinberg
Pins configured as input and have MFP_LPM_DRIVE_* flag set, can have a wrong output value for some period of time (spike) during the suspend sequence. This can happen because the direction of the pins (GPDR) is set by software and the output level is set by hardware (PGSR) at a later stage. Fix the above potential bug by setting the output levels first. Also save the actual levels of the pins before the suspend and restore them after the resume, but before the direction settings take place, so the same bug as described above will not happen in the resume sequence.

2012-04-23ARM: OMAP: fix DMA vs memory orderingRussell King
Using coherent DMA memory with the OMAP DMA engine results in unpredictable behaviour due to memory ordering issues; as things stand, there is no guarantee that data written to coherent DMA memory will be visible to the DMA hardware. This is because the OMAP dma_write() accessor contains no barriers, necessary on ARMv6 and above. The effect of this can be seen in comments in the OMAP serial driver, which incorrectly talks about cache flushing for the coherent DMA stuff. Rather than adding barriers to the accessors, add it in the DMA support code just before we enable DMA, and just after we disable DMA. This avoids having barriers for every DMA register access.

2012-04-23ARM: 7390/1: dts: versatile-pb/ab fix MMC IRQsLinus Walleij
The MMCI driver will not work without two IRQs since this is not flagged as a single-irq variant. Looking through the complex IRQ definition for the MMCI on the versatile (including an #if 1 statement forcing MMCI IRQ0 to the VIC) this appears to the the correct IRQ number for both models.

2012-04-23ARM: 7400/1: vfp: clear fpscr length and stride bits on entry to sig handlerWill Deacon
The ARM PCS mandates that the length and stride bits of the fpscr are cleared on entry to and return from a public interface. Although signal handlers run asynchronously with respect to the interrupted function, the handler itself expects to run as though it has been called like a normal function. This patch updates the state mirroring the VFP hardware before entry to a signal handler so that it adheres to the PCS. Furthermore, we disable VFP to ensure that we trap on any floating point operation performed by the signal handler and synchronise the hardware appropriately. A check is inserted after the signal handler to avoid redundant flushing if VFP was not used.

2012-04-23ARM: 7399/1: vfp: move user vfp state save/restore code out of signal.cWill Deacon
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.

2012-04-23ARM: 7398/1: l2x0: only write to debug registers on PL310Will Deacon
PL310 errata #588369 and #727915 require writes to the debug registers of the cache controller to work around known problems. Writing these registers on L220 may cause deadlock, so ensure that we only perform this operation when we identify a PL310 at probe time.

The workaround for PL310 erratum #753970 can lead to deadlock on systems with an L220 cache controller. This patch makes the workaround effective only when the cache controller is identified as a PL310 at probe time.

2012-04-23ARM: 7396/1: errata: only handle ARM erratum #326103 on affected coresWill Deacon
Erratum #326103 ("FSR write bit incorrect on a SWP to read-only memory") only affects the ARM 1136 core prior to r1p0. The workaround disassembles the faulting instruction to determine whether it was a read or write access on all v6 cores. An issue has been reported on the ARM 11MPCore whereby loading the faulting instruction may happen in parallel with that page being unmapped, resulting in a deadlock due to the lack of TLB broadcasting in hardware: http://lists.infradead.org/pipermail/linux-arm-kernel/2012-March/091561.html This patch limits the workaround so that it is only used on affected cores, which are known to be UP only. Other v6 cores can rely on the FSR to indicate the access type correctly.
