Subject: [PATCH v2 1/5] ARM: use unified assembler in macros
Date: Sun, 10 Feb 2019 00:08:58 +0100	[thread overview]
Message-ID: <8d47f3b81158fb75ce1a4013d90c00c3ea5dde66.1549753425.git.stefan@agner.ch> (raw)
In-Reply-To: <cover.1549753425.git.stefan@agner.ch>

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

Signed-off-by: Stefan Agner <stefan@agner.ch>

Changes in v2:
- Remove excessive null tokens
