Subject: [PATCH v1 12/26] KVM: arm64: Add PVM_ prefix to avoid name collisions
Date: Fri, 29 May 2026 17:55:45 +0200	[thread overview]
Message-ID: <20260529155601.2927240-13-seiden@linux.ibm.com> (raw)
In-Reply-To: <20260529155601.2927240-1-seiden@linux.ibm.com>

Rename ID_UNALLOCATED to PVM_ID_UNALLOCATED and read_id_reg to
pvm_read_id_reg to prevent future name collisions with other subsystems.
While at it, fix whitespace issues in the macro invocations
