* HWPOISON: Allow schedule_on_each_cpu() from keventdAndi Kleen2009-10-191-2/+19
| | | | | | | | | | | | | Right now when calling schedule_on_each_cpu() from keventd there is a deadlock because it tries to schedule a work item on the current CPU too. This happens via lru_add_drain_all() in hwpoison. Just call the function for the current CPU in this case. This is actually faster too.

* HWPOISON: fix/proc/meminfo alignmentHugh Dickins2009-10-191-1/+1
| | | | | | | | | Given such a long name, the kB count in /proc/meminfo's HardwareCorrupted line is being shown too far right (it does align with x86_64's VmallocChunk above, but I hope nobody will ever have that much corrupted!).

* HWPOISON: fix oops on ksm pagesHugh Dickins2009-10-191-1/+2
| | | | | | | | | | Memory failure on a KSM page currently oopses on its NULL anon_vma in page_lock_anon_vma(): that may not be much worse than the consequence of ignoring it, but it is better to be consistent with how ZERO_PAGE and hugetlb pages and other awkward cases are treated. Just skip it. Signed-off-by: Hugh Dickins <hugh.dickins@tiscali.co.uk> Signed-off-by: Andi Kleen <ak@linux.intel.com>
* HWPOISON: Fix page count leak in hwpoison late kill in do_swap_pageAndi Kleen2009-10-191-1/+2
| | | | | | | | | | | When returning due to a poisoned page drop the page count. It wasn't a fatal problem because noone cares about the page count on a poisoned page (except when it wraps), but it's cleaner to fix it. Pointed out by Linus. Signed-off-by: Andi Kleen <ak@linux.intel.com>
* HWPOISON: return early on non-LRU pagesWu Fengguang2009-10-191-25/+24
| | | | | | | | | | | | | | | | | | | Right now we have some trouble with non atomic access to page flags when locking the page. To plug this hole for now, limit error recovery to LRU pages for now. This could be better fixed by defining a suitable protocol, but let's go this simple way for now This avoids unnecessary races with __set_page_locked() and __SetPageSlab*() and maybe more non-atomic page flag operations. This loses isolated pages which are currently in page reclaim, but these are relatively limited compared to the total memory.

This allows library code to get/set the current state. - For consistency define a PR_MCE_KILL_DEFAULT value Signed-off-by: Andi Kleen <ak@linux.intel.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The auto-parser for ALC662/663/272 codecs doesn't work properly when a speaker is connected to mono NID 0x17, and doesn't handle the dynamic DAC assignment properly.

It caused by incorrect prefetch abort handling. Now every prefetch abort processes as a translation fault. To fix this we have to analyze instruction fault status register to figure out reason why we've got the abort and process it accordingly. To make IFSR different from DFSR we set bit 31 which is reserved in both IFSR and DFSR. This patch also tries to protect from future hangs on unexpected exceptions. An application will be killed if unexpected exception type was received. Signed-off-by: Kirill A. Shutemov <kirill@shutemov.name> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

Currently, on iop32x, only the lower window is available for allocations, limiting the available space to 64 MB. On iop33x the full 128 MB can be allocated, but the translation value is wrong for the upper window. The patch enables the full 128 MB space on iop32x and corrects the initialization of OMWTVR1. Redundant definitions are deleted. Tested using a Thecus N2100 board with a graphics adapter in the expansion slot. Both windows are in use: 00:05.0 VGA compatible controller: XGI Technology Inc.

Since commit c34002c1 "iop: unconditionally initialize the ATU on platforms known to be 'hosts'" this configuration also requires iop3xx_init_atu=y to be specified on the kernel command line.

This causes following compilation errors when building kernel for StrongARM (ARMv4): arch/arm/kernel/entry-common.S: Assembler messages: arch/arm/kernel/entry-common.S:129: Error: selected processor does not support `bx ip' arch/arm/kernel/entry-common.S:138: Error: selected processor does not support `bx ip' Fix these errors by using 'mov pc' instead of 'bx'.
