Subject: [PATCH v9 19/22] KVM: arm64: pkvm: Consolidate include files
Date: Wed, 13 Oct 2021 13:03:43 +0100	[thread overview]
Message-ID: <20211013120346.2926621-9-maz@kernel.org> (raw)
In-Reply-To: <20211013120346.2926621-1-maz@kernel.org>

kvm_fixed_config.h is pkvm specific, and would be better placed
near its users. At the same time, include/nvhe/sys_regs.h is now
almost empty.

Merge the two into arch/arm64/kvm/hyp/include/nvhe/fixed_config.h.
