From: William Breathitt Gray Date: Sun, 1 May 2016 21:50:29 +0000 (-0400) Subject: isa: Decouple X86_32 dependency from the ISA Kconfig option X-Git-Tag: v4.7-rc1~91^2~12 X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=8ac0fba2da41620f4931a1007c71b0d4723eb02a;p=linux.git isa: Decouple X86_32 dependency from the ISA Kconfig option The introduction of the ISA_BUS option blocks the compilation of ISA drivers on non-x86 platforms. The ISA_BUS configuration option should not be necessary if the X86_32 dependency can be decoupled from the ISA configuration option. This patch both removes the ISA_BUS configuration option entirely and removes the X86_32 dependency from the ISA configuration option.
