pkey_set() and pkey_get() were syscalls present in older versions
of the protection keys patches.  They were fully excised from the
x86 code, but some cruft was left in the generic syscall code.  The
C++ comments were intended to help to make it more glaring to me to
fix them before actually submitting them.  That technique worked,
but later than I would have liked.

I test-compiled this for arm64.

There are two separate issues that can lead to corrupted free space
trees.

1. The free space tree bitmaps had an endianness issue on big-endian
   systems which is fixed by an earlier patch in this series.
2. btrfs-progs before v4.7.3 modified filesystems without updating the
   free space tree.

To catch both of these issues at once, we need to force the free space
tree to be rebuilt. To do so, add a FREE_SPACE_TREE_VALID compat_ro bit.
If the bit isn't set, we know that it was either produced by a broken
big-endian kernel or may have been corrupted by btrfs-progs.

This also provides us with a way to add rudimentary read-write support
for the free space tree to btrfs-progs: it can just clear this bit and
have the kernel rebuild the free space tree.

This patch adds a simple device driver to expose the iBT interface on
Aspeed SOCs (AST2400 and AST2500) as a character device. Such SOCs are
commonly used as BMCs (BaseBoard Management Controllers) and this
driver implements the BMC side of the BT interface.

The BT (Block Transfer) interface is used to perform in-band IPMI
communication between a host and its BMC. Entire messages are buffered
before sending a notification to the other end, host or BMC, that
there is data to be read. Usually, the host emits requests and the BMC
responses but the specification provides a mean for the BMC to send
SMS Attention (BMC-to-Host attention or System Management Software
attention) messages.

For this purpose, the driver introduces a specific ioctl on the
device: 'BT_BMC_IOCTL_SMS_ATN' that can be used by the system running
on the BMC to signal the host of such an event.

The device name defaults to '/dev/ipmi-bt-host'
