Subject: [PATCH] [RESEND] ARM: davinci: fix sleep.S build error on ARMv4
Date: Mon, 22 Jul 2019 16:51:50 +0200
Message-ID: <20190722145211.1154785-1-arnd@arndb.de> (raw)

When building a multiplatform kernel that includes armv4 support,
the default target CPU does not support the blx instruction,
which leads to a build failure:

arch/arm/mach-davinci/sleep.S: Assembler messages:
arch/arm/mach-davinci/sleep.S:56: Error: selected processor does not support `blx ip' in ARM mode

Add a .arch statement in the sources to make this file build.
