Subject: [PATCH 1/5] ARM: use unified assembler in macros
Date: Thu,  7 Feb 2019 10:48:25 +0100	[thread overview]
Message-ID: <5b710816f634307d6a67ffcf7e4b538818dcb2a3.1549532513.git.stefan@agner.ch> (raw)
In-Reply-To: <cover.1549532513.git.stefan@agner.ch>

Use unified assembler syntax (UAL) in macros. Divided syntax is
considered depricated. This will also allow to build the kernel
using LLVM's integrated assembler.
