We fix the check in 1084, which was 1084 if (addr->channel > IPMI_NUM_CHANNELS) { 1085 spin_lock_irqsave(&intf->counter_lock, flags); 1086 intf->sent_invalid_commands++; 1087 spin_unlock_irqrestore(&intf->counter_lock, flags); 1088 rv = -EINVAL; 1089 goto out_err; 1090 } addr->channel is used in 1092 if (intf->channels[addr->channel].medium Definitions involved: 221 struct ipmi_channel channels[IPMI_MAX_CHANNELS]; 134 #define IPMI_MAX_CHANNELS 8 In /linux-2.6.12-rc6/include/linux/ipmi.h 148 #define IPMI_NUM_CHANNELS 0x10 Signed-off-by: -

The check in 627 BUG_ON(index > SG_MEMPOOL_NR); with SG_MEMPOOL_NR defined in 32 #define SG_MEMPOOL_NR (sizeof(scsi_sg_pools)/sizeof(struct scsi_host_sg_pool)) was not sufficient. sgp, set in 629 sgp = scsi_sg_pools + index; is dereferenced in 630 mempool_free(sgl, sgp->pool); Signed-off-by:

Variable "c" was declared as an unsigned int, but used in: 125 for (i=0 ; (c=read(fd, buf, sizeof(buf)))>0 ; i+=c ) 126 if (write(1, buf, c) != c) 127 die("Write call failed"); (akpm: read() can return -1. If it does, we fill the disk up with garbage). Signed-off-by: -

This patch cleans up asm-ppc64/byteorder.h to enable ___arch__swab16 and ___arch__swab32 which are marked TODO currently. It removes ___arch__swab64 because ppc64 does not have short instruction combinations for swab64, the recent gcc generates enough smart code that is equivalent to hand assembled code under my tests.

In the case of buffered AIO, in the aio retry path (aio_run_iocb), when the retry method returns EIOCBRETRY the kicked iocb is added to the context run list but is never queued onto the work queue. The request therefore is never completed. This patch fixes that by adding the appropriate call to aio_queue_work in aio_run_aiocb so that subsequent retries will be handled by the aio worker thread.

As Steven Rostedt pointed out, there are 2 problems with ITIMER_REAL timers. 1. do_setitimer() does not call del_timer_sync() in case when the timer is not pending (it_real_value() returns 0). This is wrong, the timer may still be running, and it can rearm itself. 2. It calls del_timer_sync() with tsk->sighand->siglock held. This is deadlockable, because timer's handler needs this lock too. Signed-off-by:

This patch tweaks idle thread setup semantics a bit: instead of setting NEED_RESCHED in init_idle(), we do an explicit schedule() before calling into cpu_idle(). This patch, while having no negative side-effects, enables wider use of cond_resched()s. (which might happen in the stock kernel too, but it's particulary important for voluntary-preempt) Signed-off-by:

Currently we cap request allocations at q->nr_requests, but we allow a batching io context to allocate up to 32 more (default setting). This can flood the queue with request allocations, with only a few batching processes. The real fix would be to limit the number of batchers, but as that isn't currently tracked, I suggest we just cap the maximum number of allocated requests to eg 50% over the limit. This was observed in real life, users typically see this as vmstat bo numbers going off the wall with seconds of no queueing afterwards. Behaviour this bursty is not beneficial. Signed-off-by:

Patch from Tony Lindgren This patch was suggested by RMK, and adds a warning on the accuracy of timekeeping when using dynamic tick on some platforms. Depending on the timer implementation, dynamic tick may affect the accuracy of timekeeping. Currently at least OMAP is known to have accurate timekeeping with dynamic tick. Signed-off-by:

Now that we have access to the whole MCFG table, let's properly use it for all pci device accesses (as that's what it is there for, some boxes don't put all the busses into one entry.) If, for some reason, the table is incorrect, we fallback to the "old style" of mmconfig accesses, namely, we just assume the first entry in the table is the one for us, and blindly use it.

This patch is the first step in properly handling the MCFG PCI table. It defines the structures properly, and saves off the table so that the pci mmconfig code can access it. It moves the parsing of the table a little later in the boot process, but still before the information is needed. Signed-off-by: -

drivers/pci/hotplug/cpqphp_core.c calls cpqphp_event_start_thread() in one_time_init(), which is called whenever the hardware is probed. Unfortunately, cpqphp_event_stop_thread() is *always* called when the module is unloaded. If the hardware is never probed, then cpqphp_event_stop_thread() tries to manipulate a couple of uninitialized mutexes. Signed-off-by:
