ext4: Add EXT4_IOC_TRIM ioctl to handle batched discard
Filesystem independent ioctl was rejected as not common enough to be in
core vfs ioctl. Since we still need to access to this functionality this
commit adds ext4 specific ioctl EXT4_IOC_TRIM to dispatch
ext4_trim_fs().
It takes fstrim_range structure as an argument. fstrim_range is definec in
the include/linux/fs.h and its definition is as follows.
struct fstrim_range {
__u64 start;
__u64 len;
__u64 minlen;
}
start - first Byte to trim
len - number of Bytes to trim from start
minlen - minimum extent length to trim, free extents shorter than this
number of Bytes will be ignored. This will be rounded up to fs
block size.
After the FITRIM is done, the number of actually discarded Bytes is stored
in fstrim_range.len to give the user better insight on how much storage
space has been really released for wear-leveling.

This reverts commit
59365d136d205cc20fe666ca7f89b1c5001b0d5a.
It turns out that this can break certain existing user land setups.
Quoth Sarah Sharp:
"On Wednesday, I updated my branch to commit
460781b from linus' tree,
and my box would not boot. klogd segfaulted, which stalled the whole
system.
At first I thought it actually hung the box, but it continued booting
after 5 minutes, and I was able to log in. It dropped back to the
text console instead of the graphical bootup display for that period
of time. dmesg surprisingly still works. I've bisected the problem
down to this commit (commit
59365d136d205cc20fe666ca7f89b1c5001b0d5a)
The box is running klogd 1.5.5ubuntu3 (from Jaunty). Yes, I know
that's old. I read the bit in the commit about changing the
permissions of kallsyms after boot, but if I can't boot that doesn't
help."
So let's just keep the old default, and encourage distributions to do
the "chmod -r /proc/kallsyms" in their bootup scripts. This is not
worth a kernel option to change default behavior, since it's so easily
done in user space.

ext4: ext4_fill_super shouldn't return 0 on corruption
At the start of ext4_fill_super, ret is set to -EINVAL, and any failure path
out of that function returns ret. However, the generic_check_addressable
clause sets ret = 0 (if it passes), which means that a subsequent failure (e.g.
a group checksum error) returns 0 even though the mount should fail. This
causes vfs_kern_mount in turn to think that the mount succeeded, leading to an
oops.

drm/i915: Do not hold mutex when faulting in user addresses
Linus Torvalds found that it was rather trivial to trigger a system
freeze:
In fact, with lockdep, I don't even need to do the sysrq-d thing: it
shows the bug as it happens. It's the X server taking the same lock
recursively.
Here's the problem:
=============================================
[ INFO: possible recursive locking detected ]
2.6.37-rc2-00012-gbdbd01a #7
---------------------------------------------
Xorg/2816 is trying to acquire lock:
(&dev->struct_mutex){+.+.+.}, at: [<
ffffffff812c626c>] i915_gem_fault+0x50/0x17e
but task is already holding lock:
(&dev->struct_mutex){+.+.+.}, at: [<
ffffffff812c403b>] i915_mutex_lock_interruptible+0x28/0x4a
other info that might help us debug this:
2 locks held by Xorg/2816:
#0: (&dev->struct_mutex){+.+.+.}, at: [<
ffffffff812c403b>] i915_mutex_lock_interruptible+0x28/0x4a
#1: (&mm->mmap_sem){++++++}, at: [<
ffffffff81022d4f>] page_fault+0x156/0x37b
This recursion was introduced by rearranging the locking to avoid the
double locking on the fast path (
4f27b5d and
fbd5a26d) and the
introduction of the prefault to encourage the fast paths (
b5e4f2b). In
order to undo the problem, we rearrange the code to perform the access
validation upfront, attempt to prefault and then fight for control of the
mutex. the best case scenario where the mutex is uncontended the
prefaulting is not wasted.

ipv6: Expose IFLA_PROTINFO timer values in msecs instead of jiffies
IFLA_PROTINFO exposes timer related per device settings in jiffies.
Change it to expose these values in msecs like the sysctl interface
does.
I did not find any users of IFLA_PROTINFO which rely on any of these
values and even if there are, they are likely already broken because
there is no way for them to reliably convert such a value to another
time format.

hardirq.h: needs sched.h if using BKL
This really isn't the right thing to do, and strictly speaking we should
have the BKL depth count in the thread info right next to the preempt

However, since that would involve a patch to all architectures, and the
BKL is finally going away, it's simply not worth the effort to do the
RightThing(tm). Just re-instate the <linux/sched.h> include that we

This appears to be due to checking the wrong permission bits in the
instruction_tlb_miss handling if the address that faulted was in vmalloc
space. We need to look at the supervisor execute (_PAGE_BAP_SX) bit and
not the user bit (_PAGE_BAP_UX/_PAGE_EXEC).
Also removed a branch level since it did not appear to be used.

powerpc/mm: Fix pgtable cache cleanup with CONFIG_PPC_SUBPAGE_PROT
commit
d28513bc7f675d28b479db666d572e078ecf182d
Author: David Gibson <david@gibson.dropbear.id.au>
subpage_protection() was changed to to take an mm rather a pgdir but it
didn't change calling site in hashpage_preload(). The change wasn't
noticed at compile time since hashpage_preload() used a void* as the
parameter to subpage_protection().
This is obviously wrong and can trigger the following crash when
CONFIG_SLAB, CONFIG_DEBUG_SLAB, CONFIG_PPC_64K_PAGES
CONFIG_PPC_SUBPAGE_PROT are enabled.
