Subject: [PATCH RFC/RFT 1/3] efi/libstub: Export efi_low_alloc_above() to other units
Date: Wed,  9 Sep 2020 18:16:21 +0300	[thread overview]
Message-ID: <20200909151623.16153-2-ardb@kernel.org> (raw)
In-Reply-To: <20200909151623.16153-1-ardb@kernel.org>

Permit arm32-stub.c to access efi_low_alloc_above() in a subsequent
patch by giving it external linkage and declaring it in efistub.h.
