2010-03-24genirq: Protect access to irq_desc->action in can_request_irq()Thomas Gleixner1-0/+4
can_request_irq() accesses and dereferences irq_desc->action w/o holding irq_desc->lock. So action can be freed on another CPU before it's dereferenced. Unlikely, but ... Protect it with desc->lock. Signed-off-by: Thomas Gleixner <[email protected]>

2010-03-24[S390] fix broken proc interface for sclp_asyncHans-Joachim Picht1-0/+1
This patch now allows the use of the proc interface to either activate or deactivate call home on panic. e.g. echo 1 > /proc/sys/kernel/callhome strict_strtoul() requires _either_'\n\0' _or_ '\0' termination. This was missing and therefore the interface did not recognise valid input. Signed-off-by: Hans-Joachim Picht <[email protected]> Signed-off-by: Martin Schwidefsky <[email protected]>

2010-03-24[S390] smp: fix lowcore allocationHeiko Carstens1-2/+2
The intermediate lowcore for CONFIG_SMP is allocated using a call to __alloc_bootmem() with a goal of 0. That however doesn't guarantee that the allocated piece of memory is below 2GB.

2010-03-24[S390] zcore: CPU registers are not saved under LPARMichael Holzheu4-32/+32
To save the registers for all CPUs a sigp "store status" is done that stores the registers to address absolute zero. To access storage at absolute zero, normally the address of the prefix register of the accessing CPU has to be used. This does not work when large pages are active (currently only under LPAR). In order to fix that problem, instead of memcpy memcpy_real is used, which switches to real mode where prefixing works.

2010-03-24pcmcia: use dev_pm_ops for class pcmcia_socket_classDominik Brodowski19-288/+66
Instead of requiring PCMCIA socket drivers to call various functions during their (bus) resume and suspend functions, register an own dev_pm_ops for this class. This fixes several suspend/resume bugs seen on db1xxx-ss, and probably on some other socket drivers, too. With regard to the asymmetry with only _noirq suspend, but split up resume, please see bug 14334 and commit 9905d1b411946fb3 . Signed-off-by: Dominik Brodowski <[email protected]>

The new-style dev_pm_ops provide callbacks for both IRQs enabled and disabled. However, the _noirq variants were only called for buses registered with a device, not for classes and types.

2010-03-24ALSA: cmipci: work around invalid PCM pointerClemens Ladisch1-3/+11
When the CMI8738 FRAME2 register is read, the chip sometimes (probably when wrapping around) returns an invalid value that would be outside the programmed DMA buffer. This leads to an inconsistent PCM pointer that is likely to result in an underrun. To work around this, read the register multiple times until we get a valid value; the error state seems to be very short-lived.

2010-03-23bnx2: Fix netpoll crash.Benjamin Li1-2/+4
The bnx2 driver calls netif_napi_add() for all the NAPI structs during ->probe() time but not all of them will be used if we're not in MSI-X mode. This creates a problem for netpoll since it will poll all the NAPI structs in the dev_list whether or not they are scheduled, resulting in a crash when we access structure fields not initialized for that vector. We fix it by moving the netif_napi_add() call to ->open() after the number of IRQ vectors has been determined.

nilfs_wait_on_logs has a potential to slip out before completion of all bio requests when it met an error. This synchronization fault may cause unexpected results, for instance, violative access to freed segment buffers from an end-bio callback routine.

2010-03-23time: Fix accumulation bug triggered by long delay.John Stultz1-1/+2
The logarithmic accumulation done in the timekeeping has some overflow protection that limits the max shift value. That means it will take more then shift loops to accumulate all of the cycles. This causes the shift decrement to underflow, which causes the loop to never exit. The simplest fix would be simply to do a: if (shift) shift--; However that is not optimal, as we know the cycle offset is larger then the interval << shift, the above would make shift drop to zero, then we would be spinning for quite awhile accumulating at interval chunks at a time. Instead, this patch only decreases shift if the offset is smaller then cycle_interval << shift. This makes sure we accumulate using the largest chunks possible without overflowing tick_length, and limits the number of iterations through the loop. This issue was found and reported by Sonic Zhang, who also tested the fix. Many thanks your explanation and testing!

According to the report from Andreas Beckmann (Message-ID: <[email protected]>), nilfs in 2.6.33 kernel got stuck after a disk full error. This turned out to be a regression by log writer updates merged at kernel 2.6.33. nilfs_segctor_abort_construction, which is a cleanup function for erroneous cases, was skipping writeback completion for some logs.

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.

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.
