2011-07-11PM: Reintroduce dropped call to check_wakeup_irqsColin Cross
Patch 2e711c04dbbf7a7732a3f7073b1fc285d12b369d (PM: Remove sysdev suspend, resume and shutdown operations) deleted sysdev_suspend(), which was being relied on to call check_wakeup_irqs() in suspend. If check_wakeup_irqs() is not called, wake interrupts that are pending when suspend is entered may be lost. It also breaks IRQCHIP_MASK_ON_SUSPEND, which is handled in check_wakeup_irqs(). This patch adds a call to check_wakeup_irqs() in syscore_suspend(), similar to what was deleted in sysdev_suspend(). Signed-off-by: Colin Cross <ccross@android.com> Signed-off-by: Rafael J.

2011-07-11neigh: Store hash shift instead of mask.David S. Miller
And mask the hash function result by simply shifting down the "->hash_shift" most significant bits. Currently which bits we use is arbitrary since jhash produces entropy evenly across the whole hash function result. But soon we'll be using universal hashing functions, and in those cases more entropy exists in the higher bits than the lower bits, because they use multiplies. Signed-off-by: David S.

This driver handles the variants pca9530-pca9533, so it chose the name "pca953x". However, there is a gpio driver which decided on the same name. As a result, those two can't be loaded at the same time. Add a subsystem prefix to make the driver name unique. Device matching will not suffer, because both are I2C drivers which match using a i2c_device_id-table which is not altered.

2011-07-08mm/nommu.c: fix remap_pfn_range()Bob Liu
remap_pfn_range() means map physical address pfn<<PAGE_SHIFT to user addr. For nommu arch it's implemented by vma->vm_start = pfn << PAGE_SHIFT which is wrong acroding the original meaning of this function. And some driver developer using remap_pfn_range() with correct parameter will get unexpected result because vm_start is changed. It should be implementd like addr = pfn << PAGE_SHIFT but which is meanless on nommu arch, this patch just make it simply return. Parameter name and setting of vma->vm_flags also be fixed.

2011-07-08w1: ds1wm: add a reset recovery parameterJean-François Dagenais
This fixes a regression in 3.0 reported by Paul Parsons regarding the removal of the msleep(1) in the ds1wm_reset() function: : The linux-3.0-rc4 DS1WM 1-wire driver is logging "bus error, retrying" : error messages on an HP iPAQ hx4700 PDA (XScale-PXA270): : : <snip> : Driver for 1-wire Dallas network protocol. : DS1WM w1 busmaster driver - (c) 2004 Szabolcs Gyurko : 1-Wire driver for the DS2760 battery monitor chip - (c) 2004-2005, Szabolcs Gyurko : ds1wm ds1wm: pass: 1 bus error, retrying : ds1wm ds1wm: pass: 2 bus error, retrying : ds1wm ds1wm: pass: 3 bus error, retrying : ds1wm ds1wm: pass: 4 bus error, retrying : ds1wm ds1wm: pass: 5 bus error, retrying : ... : : The visible result is that the battery charging LED is erratic; sometimes : it works, mostly it doesn't. : : The linux-2.6.39 DS1WM 1-wire driver worked OK. I haven't tried 3.0-rc1, : 3.0-rc2, or 3.0-rc3. This sleep should not be required on normal circuitry provided the pull-ups on the bus are correctly adapted to the slaves. Unfortunately, this is not always the case. The sleep is restored but as a parameter to the probe function in the pdata.

2011-07-08memcg: fix numa scan information update to be triggered by memory eventKAMEZAWA Hiroyuki
commit 889976dbcb12 ("memcg: reclaim memory from nodes in round-robin order") adds an numa node round-robin for memcg. But the information is updated once per 10sec. This patch changes the update trigger from jiffies to memcg's event count. After this patch, numa scan information will be updated when we see 1024 events of pagein/pageout under a memcg.

2011-07-08memcg: fix reclaimable lru check in memcgKAMEZAWA Hiroyuki
Now, in mem_cgroup_hierarchical_reclaim(), mem_cgroup_local_usage() is used for checking whether the memcg contains reclaimable pages or not. If no pages in it, the routine skips it. But, mem_cgroup_local_usage() contains Unevictable pages and cannot handle "noswap" condition correctly. This doesn't work on a swapless system. This patch adds test_mem_cgroup_reclaimable() and replaces mem_cgroup_local_usage(). test_mem_cgroup_reclaimable() see LRU counter and returns correct answer to the caller. And this new function has "noswap" argument and can see only FILE LRU if necessary.

2011-07-08mm: __tlb_remove_page() check the correct batchShaohua Li
__tlb_remove_page() switches to a new batch page, but still checks space in the old batch. This check always fails, and causes a forced tlb flush.
