Subject: kbuild, suspend, x86: fix rebuild of wakeup.bin
X-Git-Tag: upstream/snapshot3+hdmi~25155^2~10
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=4c6214c75a5aca5417156a47cd890b128c5f0637;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git

kbuild, suspend, x86: fix rebuild of wakeup.bin

In kernel/acpi/realmode/Makefile use the 'always'
variable to say that wakeup.bin should always
be made.

In acpi/Makefile we then do not need to specify the
requested target and we avoid the message from make:

   `arch/x86/kernel/acpi/realmode/wakeup.bin' is up to date.

Add wakeup.lds to list af targets to avoid rebuilding
wakeup.bin - from Roland McGrath.
