This reverts commit 1b0997f5, which in turn reverted 34ea80ec (which is thus re-instated). Quoth James Bottomley: "All it's doing is deferring the device_put() from the scsi_put_command() to after the scsi_run_queue(), which doesn't fix the sleep while atomic problem of the device release method. In both cases we still get the semaphore in atomic context problem which is caused by scsi_reap_target() doing a device_del(), which I assumed (wrongly) was valid from atomic context." who also promised to fix scsi_reap_target().

The raid5 stripe cache was recently changed from fixed size (NR_STRIPES) to variable size (conf->max_nr_stripes). However there are two places that still use the constant and as a result, reducing the size of the stripe cache can result in a deadlock. Signed-off-by:

This has been broken for months. On resume, we call acpi_pci_link_set() with interrupts off, so we get a warning when we try to do a kmalloc of non atomic memory. The actual allocation is just 2 long's (plus extra byte for some reason I can't fathom), so a simple conversion to GFP_ATOMIC is probably the safest way to fix this. The error looks like this.. Debug: sleeping function called from invalid context at mm/slab.c:2486 in_atomic():0, irqs_disabled():1 [<c0143f6c>] kmem_cache_alloc+0x40/0x56 [<c0206a2e>] acpi_pci_link_set+0x3f/0x17f [<c0206f96>] irqrouter_resume+0x1e/0x3c [<c0239bca>] __sysdev_resume+0x11/0x6b [<c0239e88>] sysdev_resume+0x34/0x52 [<c023de21>] device_power_up+0x5/0xa Signed-off-by:

Hitting BUG_ON() in __alloc_bootmem_core() when there is no free page available in the first node's memory. For the case of kdump on PPC64 (Power 4 machine), the captured kernel is used two memory regions - memory for TCE tables (tce-base and tce-size at top of RAM and reserved) and captured kernel memory region (crashk_base and crashk_size). Since we reserve the memory for the first node, we should be returning from __alloc_bootmem_core() to search for the next node (pg_dat). Currently, find_next_zero_bit() is returning the n^th bit (eidx) when there is no free page. Then, test_bit() is failed since we set 0xff only for the actual size initially (init_bootmem_core()) even though rounded up to one page for bdata->node_bootmem_map. We are hitting the BUG_ON after failing to enter second "for" loop. Signed-off-by:

I realized ZONE_DMA32 has a trivial bug at Kconfig for ia64. In include/linux/gfp.h on 2.6.15-rc5-mm1, CONFIG is define like followings. #ifdef CONFIG_DMA_IS_DMA32 #define __GFP_DMA32 ((__force gfp_t)0x01) /* ZONE_DMA is ZONE_DMA32 */ : : So, CONFIG_"ZONE"_DMA_IS_DMA32 is clearly wrong.

The bd622663 commit broke the UCB1x00 touchscreen driver since the idev structure was assumed to be into the ts structure, simply casting the former to the later in a couple places. This patch fixes those, and also cache the idev pointer between multiple calls to input_report_abs() to avoid growing the compiled code needlessly. Signed-off-by:

When multiple probes are registered at the same address and if due to some recursion (probe getting triggered within a probe handler), we skip calling pre_handlers and just increment nmissed field. The below patch make sure it walks the list for multiple probes case. Without the below patch we get incorrect results of nmissed count for multiple probe case. Signed-off-by:

For Kprobes critical path is the path from debug break exception handler till the control reaches kprobes exception code. No probes can be supported in this path as we will end up in recursion. This patch prevents this by moving the below function to safe __kprobes section onto which no probes can be inserted. Signed-off-by:

The IPMI specifcation says the generator ID is 0x20, but that is for bits 7-1. Bit 0 is set to specify it is a software event. The correct value is 0x41. Without this fix, panic events written into the System Event Log appear to come from an "unknown" generator, rather than from the kernel. Signed-off-by:
