Subject: [PATCH v1 2/2] kexec_core: Drop redundant pm_restore_gfp_mask() call

From: Rafael J. Wysocki <rafael.j.wysocki@...el.com>

Drop the direct pm_restore_gfp_mask() call from the KEXEC_JUMP flow in
kernel_kexec() because it is redundant.  Namely, dpm_resume_end()
called beforehand in the same code path invokes that function and
it is sufficient to invoke it once.
