Subject: [PATCH 5/8] x86: silence build with "make -s"
Date: Wed, 19 Jul 2017 14:53:03 +0200	[thread overview]
Message-ID: <20170719125310.2487451-6-arnd@arndb.de> (raw)
In-Reply-To: <20170719125310.2487451-1-arnd@arndb.de>

Every kernel build on x86 will result in some output:

Setup is 13084 bytes (padded to 13312 bytes).
System is 4833 kB
CRC 6d35fa35
Kernel: arch/x86/boot/bzImage is ready  (#2)

This shuts it up, so that 'make -s' is truely silent as long as
everything works. Building without '-s' should produce unchanged
output.
