Subject: [PATCH v2 2/2] tracing: enable syscall optimization for MIPS
Date: Fri, 15 Nov 2019 23:44:49 +0000 [thread overview]
Message-ID: <20191115234314.21599-2-hnaveed@wavecomp.com> (raw)
In-Reply-To: <20191022174551.2fcc85fd@gandalf.local.home>
Since MIPS architecture has a sparse syscall array, select the
HAVE_SPARSE_SYSCALL_NR to save space.
