5cfc8ee0 (ARM: convert arm to arch_gettimeoffset()) marked all of at91 AND at91x40 as needing ARCH_USES_GETTIMEOFFSET, and hence no high res timer support / accurate clock_gettime() - But only at91x40 needs it.

Al Viro reports that calling "sys_sigsuspend(-ERESTARTNOHAND, 0, 0)" with two signals coming and being handled in kernel space results in the syscall restart being done twice. Avoid this by clearing the 'why' flag when we call the signal handling code to prevent further syscall restarts after the first.

Clearing bit 22 in the PL310 Auxiliary Control register (shared attribute override enable) has the side effect of transforming Normal Shared Non-cacheable reads into Cacheable no-allocate reads. Coherent DMA buffers in Linux always have a Cacheable alias via the kernel linear mapping and the processor can speculatively load cache lines into the PL310 controller. With bit 22 cleared, Non-cacheable reads would unexpectedly hit such cache lines leading to buffer corruption.

On the r2p0, r2p1 and r2p2 versions of the Cortex-A9, data corruption can occur if a shared cache line is replaced on one CPU as another CPU is accessing it. This workaround sets two bits in the diagnostic register of the Cortex-A9, reducing the linefill issuing capabilities of the processor and avoiding the erroneous behaviour.

On versions of the Cortex-A9 up to and including r2p2, under rare circumstances, a DMB instruction between 2 write operations may not ensure the correct visibility ordering of the 2 writes. This workaround sets a bit in the diagnostic register of the Cortex-A9, causing the DMB instruction to behave like a DSB, which functions correctly on the affected cores.

Kconfig doesn't have any knowledge of specific v7 cores, so it is possible to select errata workarounds that may cause inadvertent behaviour when executed on a core other than those targetted by the fix. This patch improves the variant and revision checking in proc-v7.S so that the primary part number is also considered when applying errata workarounds.

Dave Hylands reports: | We've observed a problem with dma_alloc_writecombine when the system | is under heavy load (heavy bus traffic). We've managed to reduce the | problem to the following snippet, which is run from a kthread in a | continuous loop: | | void *virtAddr; | dma_addr_t physAddr; | unsigned int numBytes = 256; | | for (;;) { | virtAddr = dma_alloc_writecombine(NULL, | numBytes, &physAddr, GFP_KERNEL); | if (virtAddr == NULL) { | printk(KERN_ERR "Running out of memory\n"); | break; | } | | /* access DMA memory allocated */ | tmp = virtAddr; | *tmp = 0x77; | | /* free DMA memory */ | dma_free_writecombine(NULL, | numBytes, virtAddr, physAddr); | | ...sleep here... | } | | By itself, the code will run forever with no issues. However, as we | increase our bus traffic (typically using DMA) then the *tmp = 0x77 | line will eventually cause a page fault. If we add a small delay (a | few microseconds) before the *tmp = 0x77, then we don't see a page | fault, even under heavy load. A dsb() is required after modifying the PTE entries to ensure that they will always be visible. Add this dsb().

Commit 7cfe2494 ("ARM: AMBA: Add pclk support to AMBA bus infrastructure") changed AMBA bus to handle the PCLK automatically. However, in EP93xx clock initialization is arch_initcall which is done later than AMBA device identification. This causes amba_get_enable_pclk() to fail resulting device where UARTs are not functional. So change ep93xx_clock_init() to be postcore_initcall.

The validate_event function in the ARM perf events backend has the following problems: 1.) Events that are disabled count towards the cost. 2.) Events associated with other PMUs [for example, software events or breakpoints] do not count towards the cost, but do fail validation, causing the group to fail. This patch changes validate_event so that it ignores events in the PERF_EVENT_STATE_OFF state or that are scheduled for other PMUs.

The 2.6.36-rc kernel added three new system calls: fanotify_init, fanotify_mark, and prlimit64. This patch wires them up on ARM. The only non-trivial issue here is the u64 argument to sys_fanotify_mark(), but it is the 3rd argument and thus passed in r2/r3 in both kernel and user space, so it causes no problems. Tested with a 2.6.36-rc2 EABI kernel on an ixp4xx machine.
