Subject: [PATCH 1/2] powerpc/64: drop redundant defination of spin_until_cond
Date: Fri, 11 Jun 2021 19:10:57 +0000 (UTC) [thread overview]
Message-ID: <1fff2054e5dfc00329804dbd3f2a91667c9a8aff.1623438544.git.christophe.leroy@csgroup.eu> (raw)
From: Sudeep Holla <sudeep.holla@arm.com>
linux/processor.h has exactly same defination for spin_until_cond.
Drop the redundant defination in asm/processor.h
