Subject: [PATCH 1/4] KVM: arm64: Delete duplicated label in invalid_vector
Date: Fri, 1 May 2020 11:12:01 +0100 [thread overview]
Message-ID: <20200501101204.364798-2-maz@kernel.org> (raw)
In-Reply-To: <20200501101204.364798-1-maz@kernel.org>
From: Fangrui Song <maskray@google.com>
SYM_CODE_START defines \label , so it is redundant to define \label again.
A redefinition at the same place is accepted by GNU as
(https://sourceware.org/git/?p=binutils-gdb.git;a=commit;h=159fbb6088f17a341bcaaac960623cab881b4981)
but rejected by the clang integrated assembler.
Fixes: 617a2f392c92 ("arm64: kvm: Annotate assembly using modern annoations")
