2010-03-23libata-sff: fix spurious IRQ handlingTejun Heo1-7/+36
Commit 27943620cbd960f710a385ff4a538e14ed3f1922 introduced spurious IRQ handling but it has a race condition where valid completion can be lost while trying to clear spurious IRQ leading to occassional command timeouts. This patch improves SFF interrupt handler such that 1. Once BMDMA HSM is stopped, the condition is never considered spurious. As there's no way to resume stopped BMDMA HSM, if device status doesn't agree with BMDMA status, the only way out is aborting the command (otherwise, it will just end up timing out). 2. ap->ops->sff_check_status() can be safely called to clear spurious device IRQ as it atomically returns completion status but BMDMA IRQ status can't be cleared in safe way if command is in flight. After a spurious IRQ, call ap->ops->sff_irq_clear() only if the respective device is idle and retry completion if sff_check_status() indicates command completion. Please note that ata_piix uses bmdma_status for sff_irq_check() and #2 won't weaken spurious IRQ handling even with in-flight command because if bmdma_status indicates IRQ pending but device status is not on spurious check, the next IRQ handler invocation will abort the command due to #1. This fixes bko#15537. https://bugzilla.kernel.org/show_bug.cgi?id=15537 Signed-off-by: Tejun Heo <[email protected]> Cc: Andrew Benton <[email protected]> Cc: Petr Uzel <[email protected]> Cc: Rafael J.

2010-03-23sh: Replace unsafe manipulation of MMUCRMatt Fleming2-7/+16
Setting the TI in MMUCR causes all the TLB bits in MMUCR to be cleared. Unfortunately, the TLB wired bits are also cleared when setting the TI bit, causing any wired TLB entries to become unwired. Use local_flush_tlb_all() which implements TLB flushing in a safer manner by using the memory-mapped TLB registers. As each CPU has its own PMB the modifications in pmb_init() only affect the local CPU, so only flush the local CPU's TLB.

The follwing commit breaks SH-Mobile on non-ARM platforms: "8a77b8d serial: sh-sci: Support ARM-based SH-Mobile CPUs." The commit assumed that CONFIG_ARCH_SHMOBILE only was set on ARM platforms, but it turns out that this kconfig is also set by all SH-based SoCs. Sh7724 and other older SH-Mobile SoCs are all broken without this fix. This patch converts the "defined(CONFIG_ARCH_SHMOBILE)" into one "defined()" per SoC model - similar to existing SH code.

2010-03-22netfilter: xt_recent: fix regression in rules using a zero hit_countPatrick McHardy1-1/+1
Commit 8ccb92ad (netfilter: xt_recent: fix false match) fixed supposedly false matches in rules using a zero hit_count. As it turns out there is nothing false about these matches and people are actually using entries with a hit_count of zero to make rules dependant on addresses inserted manually through /proc. Since this slipped past the eyes of three reviewers, instead of reverting the commit in question, this patch explicitly checks for a hit_count of zero to make the intentions more clear.

2010-03-22ppc64 sys_ipc breakage in 2.6.34-rc2Anton Blanchard1-1/+1
I chased down a fail on ppc64 on 2.6.34-rc2 where an application that uses shared memory was getting a SEGV. Commit baed7fc9b580bd3fb8252ff1d9b36eaf1f86b670 ("Add generic sys_ipc wrapper") changed the second argument from an unsigned long to an int. When we call shmget the system call wrappers for sys_ipc will sign extend second (ie the size) which truncates it. It took a while to track down because the call succeeds and strace shows the untruncated size :) The patch below changes second from an int to an unsigned long which fixes shmget on ppc64 (and I assume s390, sparc64 and mips64). Signed-off-by: Anton Blanchard <[email protected]> -- I assume the function prototypes for the other IPC methods would cause us to sign or zero extend second where appropriate (avoiding any security issues). Come to think of it, the syscall wrappers for each method should do that for us as well. Signed-off-by: Linus Torvalds <[email protected]>
2010-03-22x86 / perf: Fix suspend to RAM on HP nx6325Rafael J. Wysocki1-3/+5
Commit 3f6da3905398826d85731247e7fbcf53400c18bd (perf: Rework and fix the arch CPU-hotplug hooks) broke suspend to RAM on my HP nx6325 (and most likely on other AMD-based boxes too) by allowing amd_pmu_cpu_offline() to be executed for CPUs that are going offline as part of the suspend process.

2010-03-22NFS: don't try to decode GETATTR if DELEGRETURN returned errorJeff Layton1-0/+2
The reply parsing code attempts to decode the GETATTR response even if the DELEGRETURN portion of the compound returned an error. The GETATTR response won't actually exist if that's the case and we're asking the parser to read past the end of the response. This bug is fairly benign. The parser catches this without reading past the end of the response and decode_getfattr returns -EIO. Earlier kernels however had decode_op_hdr using the READ_BUF macro, and this bug would make this printk pop any time the client got an error from a delegreturn: kernel: decode_op_hdr: reply buffer overflowed in line XXXX More recent kernels seem to have replaced this printk with a dprintk.
