Merge branch 'x86/entry' into ras/core

to fixup conflicts in arch/x86/kernel/cpu/mce/core.c so MCE specific follow
up patches can be applied without creating a horrible merge conflict
afterwards.

+
+		Following are available shutdown scopes(subtypes):

+				not used by other processing units will be
+				shut down. This may result in the FPD power
+				domain being shut down provided that no other
+				processing unit uses FPD peripherals or DRAM.
+		ps_only:	The complete PS will be shut down, including the
+				RPU, PMU, etc.  Only the PL domain (FPGA)
+				remains untouched.
+		system:		The complete system/device is shut down.
