Subject: [PATCH v3 02/17] x86/efi: Drop redundant EFI_PARAVIRT check
Date: Thu, 23 Apr 2026 17:20:27 +0200	[thread overview]
Message-ID: <20260423152024.1098465-21-ardb+git@google.com> (raw)
In-Reply-To: <20260423152024.1098465-19-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.
