James Morse 60b300975e KVM: arm/arm64: Move cc/it checks under hyp's Makefile to avoid instrumentation
[ Upstream commit 623e1528d4 ]

KVM has helpers to handle the condition codes of trapped aarch32
instructions. These are marked __hyp_text and used from HYP, but they
aren't built by the 'hyp' Makefile, which has all the runes to avoid ASAN
and KCOV instrumentation.

Move this code to a new hyp/aarch32.c to avoid a hyp-panic when starting
an aarch32 guest on a host built with the ASAN/KCOV debug options.

Fixes: 021234ef37 ("KVM: arm64: Make kvm_condition_valid32() accessible from EL2")
Fixes: 8cebe750c4 ("arm64: KVM: Make kvm_skip_instr32 available to HYP")
