For the explicit unplugging, we'd prefer to kick things off
immediately and not pay the penalty of the latency to switch
to kblockd. So let blk_finish_plug() do the run inline, while
the implicit-on-schedule-out unplug will punt to kblockd.

It's a bit of a mess currently. task->plug is being cleared
and reset in __blk_finish_plug(), and blk_finish_plug() is
testing for a NULL plug which cannot happen even from schedule()
anymore since it uses blk_needs_flush_plug() to determine
whether to call into this function at all.
So get rid of some of the cruft.

Scot Doyle demonstrated ip_options_compile() could be called with an skb
without an attached route, using a setup involving a bridge, netfilter,
and forged IP packets.
Let's make ip_options_compile() and ip_options_rcv_srr() a bit more
robust, instead of changing bridge/netfilter code.
With help from Hiroaki SHIMODA.

This patch fixes two issues:
- A disabled crtc does not use any lb, so return 0 for
lb size. This makes the display priority calculation
more exact.
- Only use 1/2 and whole lb partitions. Using smaller
partitions can cause underflow to one of the displays
if you have multiple large displays on the same lb.

The conventional format for boolean attributes in sysfs is numeric ("0" or
"1" followed by new-line). Any boolean attribute can then be read and
written using a generic function. Using the strings "yes [no]", "[yes]
no" (read), "yes" and "no" (write) will frustrate this.

On no-mmu arch, there is a memleak during shmem test. The cause of this
memleak is ramfs_nommu_expand_for_mapping() added page refcount to 2
which makes iput() can't free that pages.
The simple test file is like this:
int main(void)
{
int i;
key_t k = ftok("/etc", 42);
for ( i=0; i<100; ++i) {
int id = shmget(k, 10000, 0644|IPC_CREAT);
if (id == -1) {
printf("shmget error\n");
}
if(shmctl(id, IPC_RMID, NULL ) == -1) {
printf("shm rm error\n");
return -1;
}
}
printf("run ok...\n");
return 0;
}
And the result:
root:/> free

removed accidentally bug.h which broke UML's call tracer and bug

Without asm-generic/bug.h UML uses BUG() from arch/x86/ which makes use

a different stack for handling signals the call trace will be cut off.

This is an almost-revert of commit 93b43fa ("oom: give the dying task a
higher priority").
That commit dramatically improved oom killer logic when a fork-bomb
occurs. But I've found that it has nasty corner case. Now cpu cgroup has
strange default RT runtime. It's 0! That said, if a process under cpu
cgroup promote RT scheduling class, the process never run at all.
If an admin inserts a !RT process into a cpu cgroup by setting
rtruntime=0, usually it runs perfectly because a !RT task isn't affected
by the rtruntime knob. But if it promotes an RT task via an explicit
setscheduler() syscall or an OOM, the task can't run at all. In short,
the oom killer doesn't work at all if admins are using cpu cgroup and don't
touch the rtruntime knob.
Eventually, kernel may hang up when oom kill occur. I and the original
author Luis agreed to disable this logic.

all_unreclaimable check in direct reclaim has been introduced at 2.6.19
by following commit.
2006 Sep 25; commit 408d8544; oom: use unreclaimable info
And it went through strange history. firstly, following commit broke
the logic unintentionally.
2008 Apr 29; commit a41f24ea; page allocator: smarter retry of
costly-order allocations
Two years later, I've found obvious meaningless code fragment and
restored original intention by following commit.
2010 Jun 04; commit bb21c7ce; vmscan: fix do_try_to_free_pages()
return value when priority==0
But, the logic didn't works when 32bit highmem system goes hibernation
and Minchan slightly changed the algorithm and fixed it .
2010 Sep 22: commit d1908362: vmscan: check all_unreclaimable
in direct reclaim path
But, recently, Andrey Vagin found the new corner case. Look,
struct zone {
..
int all_unreclaimable;
..
unsigned long pages_scanned;
..
}
zone->all_unreclaimable and zone->pages_scanned are neigher atomic
variables nor protected by lock. Therefore zones can become a state of
zone->page_scanned=0 and zone->all_unreclaimable=1. In this case, current
all_unreclaimable() return false even though zone->all_unreclaimabe=1.
This resulted in the kernel hanging up when executing a loop of the form
1. fork
2. mmap
3. touch memory
4. read memory
5. munmmap
as described in
http://www.gossamer-threads.com/lists/linux/kernel/1348725#1348725
Is this ignorable minor issue? No. Unfortunately, x86 has very small dma
zone and it become zone->all_unreclamble=1 easily. and if it become
all_unreclaimable=1, it never restore all_unreclaimable=0. Why? if
all_unreclaimable=1, vmscan only try DEF_PRIORITY reclaim and
a-few-lru-pages>>DEF_PRIORITY always makes 0. that mean no page scan at
all!
Eventually, oom-killer never works on such systems. That said, we can't
use zone->pages_scanned for this purpose. This patch restore
all_unreclaimable() use zone->all_unreclaimable as old. and in addition,
to add oom_killer_disabled check to avoid reintroduce the issue of commit
d1908362 ("vmscan: check all_unreclaimable in direct reclaim path").

In __access_remote_vm() we need to check that we have found the right
vma, not the following vma before we try to access it. Otherwise we
might call the vma's access routine with an address which does not fall
inside the vma.
It was discovered on a current kernel but with an unreleased driver,
from memory it was strace leading to a kernel bad access, but it
obviously depends on what the access implementation does.
Looking at other access implementations I only see:
$ git grep -A 5 vm_operations|grep access
arch/powerpc/platforms/cell/spufs/file.c- .access = spufs_mem_mmap_access,
arch/x86/pci/i386.c- .access = generic_access_phys,
drivers/char/mem.c- .access = generic_access_phys
fs/sysfs/bin.c- .access = bin_access,
The spufs one looks like it might behave badly given the wrong vma, it
assumes vma->vm_file->private_data is a spu_context, and looks like it
would probably blow up pretty quickly if it wasn't.
generic_access_phys() only uses the vma to check vm_flags and get the
mm, and then walks page tables using the address. So it should bail on
the vm_flags check, or at worst let you access some other VM_IO mapping.
And bin_access() just proxies to another access implementation.

5520e89 ("brk: fix min_brk lower bound computation for COMPAT_BRK")
tried to get the whole logic of brk randomization for legacy
(libc5-based) applications finally right.
It turns out that the way to detect whether brk has actually been
randomized in the end or not introduced by that patch still doesn't work
for those binaries, as reported by Geert:
: /sbin/init from my old m68k ramdisk exists prematurely.
:
: Before the patch:
:
: | brk(0x80005c8e) = 0x80006000
:
: After the patch:
:
: | brk(0x80005c8e) = 0x80005c8e
:
: Old libc5 considers brk() to have failed if the return value is not
: identical to the requested value.
I don't like it, but currently see no better option than a bit flag in
task_struct to catch the CONFIG_COMPAT_BRK && randomize_va_space == 2
case.

The leds-regulator driver was ignoring the initial status of the
regulator; this resulted in rdev->use_count being incremented to 2 after
calling regulator_led_set_value() in the .probe method when a regulator
was already enabled at insmod time, which made it impossible to ever

The memory hotplug case involves calling to build_all_zonelists() which
in turns calls in to setup_zone_pageset(). The latter is marked
__meminit while build_all_zonelists() itself has no particular
annotation. build_all_zonelists() is only handed a non-NULL pointer in
the case of memory hotplug through an existing __meminit path, so the
setup_zone_pageset() reference is always safe.
The options as such are either to flag build_all_zonelists() as __ref (as
per __build_all_zonelists()), or to simply discard the __meminit
annotation from setup_zone_pageset().

Sometimes the i2c test in i2c_bit_add_bus fails
if this happens we fail to register the i2c adapter and
eventually fail to add the connector. If i2c fails,
add the connector to the user can at least force
it on.
Note that some distros set i2c-algo-bit.bit_test to 1 by
default which sometimes fails preventing the ddc i2c adapter
from being added. The i2c adapter works even if the bit test
fails, probably due to pre/post_xfer not getting called in
the test_bit function. I have another patch to follow
up on that.

This reverts commit 5808544690300071f09eef9ab83a0fb1f60cf1cd.
To quote Richard:
I don't think this should be mainlined. It was a
misunderstanding on my part. If you see all the other hdc
drivers in the same location, they all do the same thing (i.e.
clear the interrupt status first, then do the work) that
"glitch" I think I saw was actually two back-to-back
interrupts.
Sebastian (the original author of isp1760) explained it to me a
few days after my submission.

s3c_pm_show_resume_irqs() is used by some s3c_pm_arch_show_resume_irqs()
implementations, which get included through mach/pm-core.h. Add __maybe_unused
to silence warnings when it isn't used (e.g. on S3C64XX platforms).

The s3c_pm_check_resume_pin() is not being used and can be safely
removed to fix the build warning.
