From: Ingo Molnar Date: Wed, 3 Jun 2015 08:00:13 +0000 (+0200) Subject: x86/kconfig: Reorganize arch feature Kconfig select's X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=6471b825c41e6fc3cd41caa18d15142d0e121e76;p=linux-beck.git x86/kconfig: Reorganize arch feature Kconfig select's Peter Zijstra noticed that in arch/x86/Kconfig there are a lot of X86_{32,64} clauses in the X86 symbol, plus there are a number of similar selects in the X86_32 and X86_64 config definitions as well - which all overlap in an inconsistent mess. So: - move all select's from X86_32 and X86_64 to the X64 config option - sort their names, so that duplications are easier to spot - align their if clauses, so that they are easier to identify at a glance - and so that weirdnesses stand out more No change in functionality: 105 insertions(+) 105 deletions(-) Originally-from: Peter Zijlstra Cc: Andrew Morton Cc: H.
