Subject: [RFC][PATCH v4 12/32] objtool: mcount: Replace MIPS offset types
Date: Tue, 2 Jun 2020 12:50:05 -0700	[thread overview]
Message-ID: <0d0d88eefe95c90a4fa0bb08cccb15303d2a089d.1591125127.git.mhelsley@vmware.com> (raw)
In-Reply-To: <cover.1591125127.git.mhelsley@vmware.com>

Replace MIPS is_fake_mcount code using Elf_Addr with
unsigned long for the offsets. This is consistent with the way
that objtool more generally treats offsets and removes the
last use of the Elf_Addr wrapper.
