PCI: tegra: Make sure the PCIe PLL is really reset

Depending on the prior state of the controller, the PLL reset may not be
pulsed.  Clear the register bit and set it after a small delay to ensure
that the PLL is really reset.

PCI: tegra: Add Tegra124 support

The PCIe controller on Tegra124 has two root ports that can be used in a
x4/x1 or x2/x1 configuration and can run at PCIe 2.0 link speeds (up to
5 GT/s).  The PHY programming has been moved into a separate controller, so
the driver now needs to request an external PHY referenced using the device
tree.

ALSA: hda - Replace strnicmp with strncasecmp

The kernel used to contain two functions for length-delimited,
case-insensitive string comparison, strnicmp with correct semantics
and a slightly buggy strncasecmp. The latter is the POSIX name, so
strnicmp was renamed to strncasecmp, and strnicmp made into a wrapper
for the new strncasecmp to avoid breaking existing users.

To allow the compat wrapper strnicmp to be removed at some point in
the future, and to avoid the extra indirection cost, do
s/strnicmp/strncasecmp/g.

udf: Fix race between write(2) and close(2)

Currently write(2) updating i_size and close(2) of the file can race in
such a way that udf_truncate_tail_extent() called from
udf_file_release() sees old i_size but already new extents added by the
running write call. This results in complaints like:
  UDF-fs: warning (device vdb2): udf_truncate_tail_extent: Too long extent
    after EOF in inode 877: i_size: 0 lbcount: 1073739776 extent 0+1073739776
  UDF-fs: error (device vdb2): udf_truncate_tail_extent: Extent after EOF
    in inode 877

Fix the problem by grabbing i_mutex in udf_file_release() to be sure
i_size is consistent with current state of extent list. Also avoid
truncating tail extent unnecessarily when the file is still open for
writing.

ext3: Don't use MAXQUOTAS value

MAXQUOTAS value defines maximum number of quota types VFS supports. This
isn't necessarily the number of types ext3 supports and with addition of
project quotas these two numbers stop matching. So make ext3 use its
