x86/hyperv: Hide unused label

2017-03-01T09:51:40+00:00

This new 32-bit warning just showed up:

arch/x86/hyperv/hv_init.c: In function 'hyperv_init':
arch/x86/hyperv/hv_init.c:167:1: error: label 'register_msr_cs' defined but not used [-Werror=unused-label]

The easiest solution is to move the label up into the existing #ifdef that
has the goto.

drivers: hv: Turn off write permission on the hypercall page

2017-02-10T14:48:00+00:00

The hypercall page only needs to be executable but currently it is setup to
be writable as well. Fix the issue.

hv: export current Hyper-V clocksource

2017-02-10T14:40:19+00:00

As a preparation to implementing Hyper-V PTP device supporting
.getcrosststamp we need to export a reference to the current Hyper-V
clocksource in use (MSR or TSC page).

Drivers: hv: restore TSC page cleanup before kexec

2017-01-31T10:05:58+00:00

We need to cleanup the TSC page before doing kexec/kdump or the new kernel
may crash if it tries to use it.

Drivers: hv: restore hypervcall page cleanup before kexec

2017-01-31T10:05:58+00:00

We need to cleanup the hypercall page before doing kexec/kdump or the new
kernel may crash if it tries to use it. Reuse the now-empty hv_cleanup
function renaming it to hyperv_cleanup and moving to the arch specific
code.
