Subject: [PATCH v8 3/5] arm64: replace -pg with CC_FLAGS_FTRACE in mm/kasan Makefile
Date: Fri,  8 Feb 2019 16:10:14 +0100 (CET)	[thread overview]
Message-ID: <20190208151014.CD48668DDC@newverein.lst.de> (raw)
In-Reply-To: <20190208150826.44EBC68DD2@newverein.lst.de>

  In preparation for arm64 supporting ftrace built on other compiler
  options, let's have makefiles remove the $(CC_FLAGS_FTRACE)
  flags, whatever these may be, rather than assuming '-pg'.

  There should be no functional change as a result of this patch.
