Subject: [PATCH v7 19/28] x86/asm: kill the last GLOBAL user and remove the macro
Date: Wed, 30 Jan 2019 13:47:02 +0100 [thread overview]
Message-ID: <20190130124711.12463-20-jslaby@suse.cz> (raw)
In-Reply-To: <20190130124711.12463-1-jslaby@suse.cz>
Convert the remaining 32bit users and remove GLOBAL macro finally. In
particular, this means to use SYM_ENTRY for the singlestepping hack
region.
Exclude the global definition of GLOBAL from x86 too.
