[PATCH v2 0/2] Fine grain sysregs allowed to trap for nested virtualization

[Miguel Luis]

The current HCR_EL2 description includes _EL1 registers that are not affected
by NV. Let's exclude them from those ranges to implement a more fine grained
approach.

Changes v1 -> v2
 patch 1:
	fix indentation
 patch 2:
	improve commit message (Marc)
	fix indentation (Marc)
	follow kernel comment format (Marc)
	describe LRs in ranges (Marc)
	include AMEVCNTVOFF0<n>_EL2 and AMEVCNTVOFF1<n>_EL2
 patch 3:
	drop. Excluded IMPDEF range is trapped by HCR_EL2.TIDCP

v1: https://lore.kernel.org/kvmarm/20230913185209.32282-1-miguel.luis@xxxxxxxxxx/
