[PATCH 5.10 01/43] Revert "kconfig: remove kvmconfig and xenconfig shorthands"

[Greg Kroah-Hartman]

From: Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx>

This reverts commit 17a08680ab6a6c057949cb48c352933e09ea377a which is
commit 9bba03d4473df0b707224d4d2067b62d1e1e2a77 upstream.

As Pavel says at Link: https://lore.kernel.org/r/20210119182837.GA18123@xxxxxxxxxx
	I don't believe this is suitable for stable.

And he's right.  It is "after" 5.10.0, but we want to keep these targets
for all of the 5.10.y series.
