Subject: [PATCH 7/8] ARM: asm: cleanup 32-bit entry points
Date: Mon, 24 Oct 2022 08:57:15 +0200 [thread overview]
Message-ID: <20221024065716.1215046-8-a.fatoum@pengutronix.de> (raw)
In-Reply-To: <20221024065716.1215046-1-a.fatoum@pengutronix.de>
The experiment of using a common definition between ARM32 and ARM64
for ENTRY_FUNCTION_WITHSTACK was not fruitful and ARM64 no longer
uses __ARM_SETUP_STACK. Thus remove the definition and open code it for
ARM32. No functional change.
