From: Ingo Molnar Date: Wed, 28 Jan 2009 18:34:09 +0000 (+0100) Subject: x86: move mach-default/*.h files to asm/ X-Git-Tag: firefly_0821_release~13973^2~508^2~82 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=1164dd0099c0d79146a55319670f57ab7ad1d352;p=firefly-linux-kernel-4.4.55.git x86: move mach-default/*.h files to asm/ We are getting rid of subarchitecture support - move the hook files to asm/. (These are now stale and should be replaced with more explicit runtime mechanisms - but the transition is simpler this way.)
