Make sure to disable clocks and deregister any exported partitions
before returning on late probe errors.

Note that since commit ee895ccd ("misc: sram: fix enabled clock leak
on error path"), partitions are deliberately exported before enabling
the clock so we stick to that logic here. A follow up patch will address
this.

The Hyper-V feature and hint flags in hyperv-tlfs.h are all defined
with the string "X64" in the name.  Some of these flags are indeed
x86/x64 specific, but others are not.  For the ones that are used
in architecture independent Hyper-V driver code, or will be used in
the upcoming support for Hyper-V for ARM64, this patch removes the
"X64" from the name.

This patch changes the flags that are currently known to be
used on multiple architectures. Hyper-V for ARM64 is still a
work-in-progress and the Top Level Functional Spec (TLFS) has not
been separated into x86/x64 and ARM64 areas.  So additional flags
may need to be updated later.

This patch only changes symbol names.  There are no functional
changes.

Commit ea81fdf0 ("Tools: hv: vss: Skip freezing filesystems backed by
loop") added skip for filesystems backed by loop device. However, it seems
the detection of such cases is incomplete.

It was found that with 'devicemapper' storage driver docker creates the
following chain:

NAME					MAJ:MIN
loop0					7:0
..docker-8:4-8473394-pool		253:0
  ..docker-8:4-8473394-eac...		253:1

so when we're looking at the mounted device we see major '253' and not '7'.

Solve the issue by walking /sys/dev/block/*/slaves chain and checking if
there's a loop device somewhere.

Other than that, don't skip mountpoints silently when stat() fails. In case
e.g. SELinux is failing stat we don't want to skip freezing everything
without letting user know about the failure.

In architecture independent code for manipulating Hyper-V synthetic timers
and synthetic interrupts, pass in an ordinal number identifying the timer
or interrupt, rather than an actual MSR register address.  Then in
x86/x64 specific code, map the ordinal number to the appropriate MSR.
This change facilitates the introduction of an ARM64 version of Hyper-V,
which uses the same synthetic timers and interrupts, but a different
mechanism for accessing them.
