Subject: [PATCH 2/7] x86/efi: Drop redundant EFI_PARAVIRT check
Date: Fri, 10 Apr 2026 09:59:52 +0200	[thread overview]
Message-ID: <20260410075950.1687350-11-ardb+git@google.com> (raw)
In-Reply-To: <20260410075950.1687350-9-ardb+git@google.com>

From: Ard Biesheuvel <ardb@kernel.org>

efi_memblock_x86_reserve_range() exits early if EFI_PARAVIRT is set, so
there is no point in checking it a second time further down.
