d_invalidate() for positive dentry doesn't work in some cases
(vfsmount, nfsd, and maybe others). shrink_dcache_parent() by
d_invalidate() is pointless for vfat usage at all.
So, this kills it, and intead of it uses d_move().
To save old behavior, this returns alias simply for directory (don't
change pwd, etc..). the directory lookup shouldn't be important for
performance.

- Add comments for handling dcache of vfat.
- Separate case-sensitive case and case-insensitive to
vfat_revalidate() and vfat_ci_revalidate().
vfat_revalidate() doesn't need to drop case-insensitive negative
dentry on creation path.
- Current code is missing to set ->d_revalidate to the negative dentry
created by unlink/etc..
This sets ->d_revalidate always, and returns 1 for positive
dentry. Now, we don't need to change ->d_op dynamically anymore,
so this just uses sb->s_root->d_op to set ->d_op.
- d_find_alias() may return DCACHE_DISCONNECTED dentry. It's not
the interesting dentry there. This checks it.
- Add missing LOOKUP_PARENT check. We don't need to drop the valid
negative dentry for (LOOKUP_CREATE | LOOKUP_PARENT) lookup.
- For consistent filename on creation path, this drops negative dentry
if we can't see intent.

The atmel_serial driver is mismanaging its clock by leaving it on at all
times ... the whole point of clock management is to leave it off unless
it's actively needed, which conserves power!!
Although the kernel doesn't actually hang without my fix, it does
discard quite a lot of early console output.
The result still looks correct:
usart users= 1 on 35000000 Hz, for atmel_usart.0
usart users= 0 off 35000000 Hz, for atmel_usart.2

commit 3e680aae4e ("fb: convert
lock/unlock_kernel() into local fb mutex") introduced several deadlocks
in the fb_compat_ioctl() path, as mutex_lock() doesn't allow recursion,
unlike lock_kernel(). This broke frame buffer applications on 64-bit
systems with a 32-bit userland.
commit 120a37470c ("framebuffer compat_ioctl
deadlock") fixed one of the deadlocks.
This patch fixes the remaining deadlocks:
- Revert commit 120a37470c,
- Extract the core logic of fb_ioctl() into a new function do_fb_ioctl(),
- Change all callsites of fb_ioctl() where info->lock is already held to
call do_fb_ioctl() instead,
- Add sparse annotations to all routines that take info->lock.

pfn will then be >= end_pfn, which may be in a different zone or not

Now I use __first_valid_page() again after the loop to find a valid page

In ext3_sync_fs, we only wait for a commit to finish if we started it, but
there may be one already in progress which will not be synced.
In the case of a data=ordered umount with pending long symlinks which are
delayed due to a long list of other I/O on the backing block device, this
causes the buffer associated with the long symlinks to not be moved to the
inode dirty list in the second phase of fsync_super. Then, before they
can be dirtied again, kjournald exits, seeing the UMOUNT flag and the
dirty pages are never written to the backing block device, causing long
symlink corruption and exposing new or previously freed block data to
userspace.
This can be reproduced with a script created
by Eric Sandeen <sandeen@redhat.com>:
#!/bin/bash
umount /mnt/test2
mount /dev/sdb4 /mnt/test2
rm -f /mnt/test2/*
dd if=/dev/zero of=/mnt/test2/bigfile bs=1M count=512

/mnt/test2/link
umount /mnt/test2
mount /dev/sdb4 /mnt/test2
ls /mnt/test2/
umount /mnt/test2

When working with hugepages, hugetlbfs assumes that those hugepages are
smaller than MAX_ORDER. Specifically it assumes that the mem_map is
contigious and uses that to optimise access to the elements of the mem_map
that represent the hugepage. Gigantic pages (such as 16GB pages on
powerpc) by definition are of greater order than MAX_ORDER (larger than
MAX_ORDER_NR_PAGES in size). This means that we can no longer make use of
the buddy alloctor guarentees for the contiguity of the mem_map, which
ensures that the mem_map is at least contigious for maximmally aligned
areas of MAX_ORDER_NR_PAGES pages.
This patch adds new mem_map accessors and iterator helpers which handle
any discontiguity at MAX_ORDER_NR_PAGES boundaries. It then uses these to
implement gigantic page versions of copy_huge_page and clear_huge_page,
and to allow follow_hugetlb_page handle gigantic pages.

__scm_destroy() walks the list of file descriptors in the scm_fp_list

Those, in turn, can close sockets and invoke __scm_destroy() again.
There is nothing which limits how deeply this can occur.
The idea for how to fix this is from Linus. Basically, we do all of

objects hit by an fput(). Inside of the initial __scm_destroy() we
keep running the list until it is empty.

* 'upstream-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jgarzik/libata-dev:
libata: mask off DET when restoring SControl for detach
libata: implement ATA_HORKAGE_ATAPI_MOD16_DMA and apply it

sata_nv: fix generic, nf2/3 detection regression

libata restores SControl on detach; however, trying to restore
non-zero DET can cause undeterministic behavior including PMP device
going offline till power cycling. Mask off DET when restoring
SControl.

libata always uses PIO for ATAPI commands when the number of bytes to
transfer isn't multiple of 16 but quantum DAT72 chokes on odd bytes
PIO transfers. Implement a horkage to skip the mod16 check and apply
it to the quantum device.
This is reported by John Clark in the following thread.

Peter Moulder has pointed out that there is a slight chance that a
negative value might be passed to jiffies_to_msecs() in
ata_scsi_park_show(). This is fixed by saving the value of jiffies in a
local variable, thus also reducing code since the volatile variable
jiffies is accessed only once.
