The declaration for pfn_is_nosave is only available in
kernel/power/power.h. Since this function can be override in arch,
expose it globally. Having a prototype will make sure to avoid warning
(sometime treated as error with W=1) such as:
arch/powerpc/kernel/suspend.c:18:5: error: no previous pr
'perf kvm record' uses 'cycles'(if the user did not specify any event) as
the default event to profile the guest.
This will not provide any proper samples from the guest incase of
powerpc architecture, since in powerpc the PMUs are controlled by
the guest rather than the host.
Patch adds a functio
Use 'trace_imc/trace_cycles' as the default event for 'perf kvm record'

This wires up the close_range() syscall into all arches at once.

Put xmon into read-only mode for lockdown=integrity and completely

locked_vm accounting is done roughly the same way in five places, so
unify them in a helper. Standardize the debug prints, which vary
slightly, but include the helper's caller to disambiguate between
callsites.
Error codes stay the same, so user-visible behavior does too. The one
exception is th
