- blk clk is enabled when an irq arrives. The clk should be enabled, but just to make sure. - All error bits are handled no matter state machine state - All irq's will run complete() except for irq's that wasn't an event. - No more looking into status registers just in case an interrupt has happend and the irq handle wasn't executed. - irq_disable/enable are now separete functions. - clk settings calculation changed to round upwards instead of downwards. - Number of address send attempts before giving up is increased to 12 from 10 since it most times take 8 tries before getting through.

Silicon Errata 1.153 has been fixed on OMAP 3630|4430 with the use of a later version of I2C IP block. The errata impacts OMAP 2420|2430|3430, enable the workaround for these based on I2C IP block revision number instead of OMAP CPU type Signed-off-by:

There are many variants of Toshiba laptops with ALC268 codec, and it seems that a few of them don't work with model=toshiba preset since they have the secondary ALC268 codec just for HDMI output. This is a regression due to the previous clean-up work to merge all Toshiba quirk entries into a single check. This patch adds the identification of such laptops to apply the standard BIOS-probing method. Unfortunately, Toshiba laptops have all the same PCI SSID, so we need to check the codec SSID to identify each device. Tested-by:

HP Compaq 6530s and 6531s internal speaker is silence or becomes silence within 1 minute after fresh boot. It is found that pin 0x1c must be set to PIN_OUT mode to make the speaker work.

If node_load[] is cleared everytime build_zonelists() is called,node_load[] will have no help to find the next node that should appear in the given node's fallback list. Because of the bug, zonelist's node_order is not calculated as expected. This bug affects on big machine, which has asynmetric node distance. [synmetric NUMA's node distance] 0 1 2 0 10 12 12 1 12 10 12 2 12 12 10 [asynmetric NUMA's node distance] 0 1 2 0 10 12 20 1 12 10 14 2 20 14 10 This (my bug) is very old but no one has reported this for a long time. Maybe because the number of asynmetric NUMA is very small and they use cpuset for customizing node memory allocation fallback.

KOSAKI Motohiro authored
The commit 2ff05b2b (oom: move oom_adj value) moveed the oom_adj value to the mm_struct. It was a very good first step for sanitize OOM. However Paul Menage reported the commit makes regression to his job scheduler. Current OOM logic can kill OOM_DISABLED process. Why? His program has the code of similar to the following. ... set_oom_adj(OOM_DISABLE); /* The job scheduler never killed by oom */ ... if (vfork() == 0) { set_oom_adj(0); /* Invoked child can be killed */ execve("foo-bar-cmd"); } .... vfork() parent and child are shared the same mm_struct. then above set_oom_adj(0) doesn't only change oom_adj for vfork() child, it's also change oom_adj for vfork() parent. Then, vfork() parent (job scheduler) lost OOM immune and it was killed. Actually, fork-setting-exec idiom is very frequently used in userland program. We must not break this assumption. Then, this patch revert commit 2ff05b2b and related commit.

This turns out to be a bug brought by an -rc1 patch ("nilfs2: simplify remaining sget() use"). In the patch, a new "put resource" function, nilfs_put_sbinfo() was introduced to delay freeing nilfs_sb_info struct. But the nilfs_put_sbinfo() mistakenly used atomic_dec_and_test() function to check the reference count, and it caused the nilfs_sb_info was freed when user mounted a snapshot twice. This bug also suggests there was unseen memory leak in usual mount /umount operations for nilfs. Signed-off-by:Ryusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>
