OMAP3: hwmod data: add DSS DISPC RFBI DSI VENC
Hwmod needs database of all IPs in a system. This patch generates the hwmod
database for Display Sub System applicable for OMAP3430 and
OMAP36xx. DSS is also considered as an IP as DISPC, RFBI and named as dss_core.
For all the IP modules in DSS, same clock is needed for enabling. Hwmod sees
DSS IPs as independent IPs, so same clock has to be repeated for .main_clk in
each IP.
This patch defines separate hwmod databases for OMAP3430ES1 and (OMAP3430ES2 and
OMAP36xx) as OMAP3430ES1 does not have IDLEST bit to poll on for dss IP, and also
the firewall regions are different between 3430es1 and later.

arm: omap4: 4430sdp: drop ehci support
Most revisions of the OMAP4 Blaze/SDP platform do not have
the EHCI signals routed by default. The pads are routed
for the alternate HSI functionality instead, and explicit
board modifications are needed to route the signals to
the USB PHY on the board.
Also, turning on the PHY connected to the EHCI port causes
a board reboot during bootup due to an unintended short
on the rails - this affects many initial revisions of the
board, and needs a minor board mod to fix (or as a
workaround, one should not attempt to power on the
USB PHY).
Given that these boards need explicit board mods to even

TI816X: Update common omap platform files
This patch updates the common platform files with TI816X support.
The approach taken in this patch is to add TI816X as part of OMAP3 variant where
the cpu class is considered as OMAP34XX and the type is TI816X. This means, both
cpu_is_omap34xx() and cpu_is_ti816x() checks return success on TI816X.
A kernel config option CONFIG_SOC_OMAPTI816X is added under OMAP3 to include
support for TI816X build.

pci: use security_capable() when checking capablities during config space read
This reintroduces commit
47970b1b which was subsequently reverted
as
f00eaeea. The original change was broken and caused X startup
failures and generally made privileged processes incapable of reading
device dependent config space. The normal capable() interface returns
true on success, but the LSM interface returns 0 on success. This thinko
is now fixed in this patch, and has been confirmed to work properly.
So, once again...Eric Paris noted that commit de139a3 ("pci: check caps
from sysfs file open to read device dependent config space") caused the
capability check to bypass security modules and potentially auditing.
Rectify this by calling security_capable() when checking the open file's
capabilities for config space reads.

btrfs: prevent heap corruption in btrfs_ioctl_space_info()
Commit
bf5fc093c5b625e4259203f1cee7ca73488a5620 refactored
btrfs_ioctl_space_info() and introduced several security issues.
space_args.space_slots is an unsigned 64-bit type controlled by a
possibly unprivileged caller. The comparison as a signed int type
allows providing values that are treated as negative and cause the
subsequent allocation size calculation to wrap, or be truncated to 0.
By providing a size that's truncated to 0, kmalloc() will return
ZERO_SIZE_PTR. It's also possible to provide a value smaller than the
slot count. The subsequent loop ignores the allocation size when
copying data in, resulting in a heap overflow or write to ZERO_SIZE_PTR.
The fix changes the slot count type and comparison typecast to u64,
which prevents truncation or signedness errors, and also ensures that we
don't copy more data than we've allocated in the subsequent loop. Note
that zero-size allocations are no longer possible since there is already
an explicit check for space_args.space_slots being 0 and truncation of
this value is no longer an issue.

Btrfs: don't release pages when we can't clear the uptodate bits
Btrfs tracks uptodate state in an rbtree as well as in the
page bits. This is supposed to enable us to use block sizes other than
the page size, but there are a few parts still missing before that
completely works.
But, our readpage routine trusts this additional range based tracking
of uptodateness, much in the same way the buffer head up to date bits
are trusted for the other filesystems.
The problem is that sometimes we need to allocate memory in order to
split records in the rbtree, even when we are just clearing bits. This
can be difficult when our clearing function is called GFP_ATOMIC, which
can happen in the releasepage path.
So, what happens today looks like this:
releasepage called with GFP_ATOMIC
btrfs_releasepage calls clear_extent_bit
clear_extent_bit fails to allocate ram, leaving the up to date bit set
btrfs_releasepage returns success
The end result is the page being gone, but btrfs thinking the range is
up to date. Later on if someone tries to read that same page, the
btrfs readpage code will return immediately thinking the page is already
up to date.
This commit fixes things to fail the releasepage when we can't clear the
extent state bits. It covers both data pages and metadata tree blocks.

Btrfs: fix page->private races
There is a race where btrfs_releasepage can drop the
page->private contents just as alloc_extent_buffer is setting
up pages for metadata. Because of how the Btrfs page flags work,
this results in us skipping the crc on the page during IO.
This patch sovles the race by waiting until after the extent buffer
is inserted into the radix tree before it sets page private.

nfsd4: acquire only one lease per file
Instead of acquiring one lease each time another client opens a file,
nfsd can acquire just one lease to represent all of them, and reference
count it to determine when to release it.
This fixes a regression introduced by
c45821d263a8a5109d69a9e8942b8d65bcd5f31a "locks: eliminate fl_mylease
callback": after that patch, only the struct file * is used to determine
who owns a given lease. But since we recently converted the server to
share a single struct file per open, if we acquire multiple leases on
the same file from nfsd, it then becomes impossible on unlocking a lease
to determine which of those leases (all of whom share the same struct
file *) we meant to remove.

NFSD: memory corruption due to writing beyond the stat array
If nfsd fails to find an exported via NFS file in the readahead cache, it
should increment corresponding nfsdstats counter (ra_depth[10]), but due to a
bug it may instead write to ra_depth[11], corrupting the following field.
In a kernel with NFSDv4 compiled in the corruption takes the form of an
increment of a counter of the number of NFSv4 operation 0's received; since
there is no operation 0, this is harmless.
In a kernel with NFSDv4 disabled it corrupts whatever happens to be in the
memory beyond nfsdstats.
