usb: serial: ftdi_sio.c: For the FT232H FTDI_SIO_SET_BAUDRATE_REQUEST, index needs to be shifted too
the recent addition of the FT232H showed that baudrate was set wrong. See
gmane.linux.usb.general: "[ftdi_sio] FT232H support". With the old code,
the MSB of the 4 encoded fractional divider bits and more important the
clock predivider bits got lost. Adding the FT232H to the code patch were
these bits are shifted solves the problem. I verified baud rates with a
scope now.
I suspect, that the BM device probably needs these bits shifted too. But
there is no predivider bit, so this is not obvious, and a missing MSB of the
encoded fractional divider only shifts the resulting baudrate minimal.
The AM has only 3 bits of encoded fractional divider, so it is not impacted.
I have no BM device to test, so I only added a comment and left the code for
the BM untouched.

Commit a9ff4f87 "fuse: support BSD locking semantics" overlooked a
number of issues with supporing flock locks over existing POSIX
locking infrastructure:
- it's not backward compatible, passing flock(2) calls to userspace
unconditionally (if userspace sets FUSE_POSIX_LOCKS)
- it doesn't cater for the fact that flock locks are automatically
unlocked on file release
- it doesn't take into account the fact that flock exclusive locks
(write locks) don't need an fd opened for write.
The last one invalidates the original premise of the patch that flock
locks can be emulated with POSIX locks.
This patch fixes the first two issues. The last one needs to be fixed
in userspace if the filesystem assumed that a write lock will happen
only on a file operned for write (as in the case of the current fuse
library).

ARM: 7007/1: alignment: Prevent ignoring of faults with ARMv6 unaligned access model
Currently, it's possible to set the kernel to ignore alignment
faults when changing the alignment fault handling mode at runtime
via /proc/sys/alignment, even though this is undesirable on ARMv6
and above, where it can result in infinite spins where an un-fixed-
up instruction repeatedly faults.
In addition, the kernel clobbers any alignment mode specified on
the command-line if running on ARMv6 or above.
This patch factors out the necessary safety check into a couple of
new helper functions, and checks and modifies the fault handling
mode as appropriate on boot and on writes to /proc/cpu/alignment.
Prior to ARMv6, the behaviour is unchanged.
For ARMv6 and above, the behaviour changes as follows:
* Attempting to ignore faults on ARMv6 results in the mode being
forced to UM_FIXUP instead. A warning is printed if this
happened as a result of a write to /proc/cpu/alignment. The
user's UM_WARN bit (if present) is still honoured.
* An alignment= argument from the kernel command-line is now
honoured, except that the kernel will modify the specified mode
as described above. This is allows modes such as UM_SIGNAL and
UM_WARN to be active immediately from boot, which is useful for
debugging purposes.
