Commit b5dc5d4d ("block,bfq: Disable writeback throttling") disable
wbt for bfq, because different write-throttling heuristics should not
work together.

For the same reason, wbt and iocost should not work together as well,
unless admin really want to do that, dispite that performance is
affected.

This reverts commit 72a95859.

It broke reboots on big-endian MIPS and MIPS64 malta QEMU instances,
which use the syscon driver.  Little-endian is not effected, which means
likely it's important to handle regmap_get_val_endian() in this function
after all.

Commit bfca3dd3 ("kernel/utsname_sysctl.c: print kernel arch") added
a new entry to the uts_kern_table[] array, but didn't update the
UTS_PROC_xyz enumerators of older entries, breaking anything that used
them.

Which is admittedly not many cases: it's really just the two uses of
uts_proc_notify() in kernel/sys.c.  But apparently journald-systemd
actually uses this to detect hostname changes.

If a protocol doesn't support zerocopy it will silently fall back to
copying. This type of behaviour has always been a source of troubles
so it's better to fail such requests instead.

The KVM_X86_SET_MSR_FILTER ioctls contains a pointer in the passed in
struct which means it has a different struct size depending on whether
it gets called from 32bit or 64bit code.

This patch introduces compat code that converts from the 32bit struct to
its 64bit counterpart which then gets used going forward internally.
With this applied, 32bit QEMU can successfully set MSR bitmaps when
running on 64bit kernels.

When an extended state component is not present in fpstate, but in init
state, the function copies from init_fpstate via copy_feature().

But, dynamic states are not present in init_fpstate because of all-zeros
init states. Then retrieving them from init_fpstate will explode like this:

Adjust the 'mask' to zero out the userspace buffer for the features that
are not available both from fpstate and from init_fpstate.

The dynamic features depend on the compacted XSAVE format. Ensure it is
enabled before reading XCOMP_BV in init_fpstate.

Pull selinux fix from Paul Moore:
 "A small SELinux fix for a GFP_KERNEL allocation while a spinlock is
  held.

  The patch, while still fairly small, is a bit larger than one might
  expect from a simple s/GFP_KERNEL/GFP_ATOMIC/ conversion because we
  added support for the function to be called with different gfp flags
  depending on the context, preserving GFP_KERNEL for those cases that
  can safely sleep"
