Subject: [PATCH 1/9] AOUT: Move STACK_TOP[_MAX] to asm/processor.h [try #6]
Date: Wed, 14 Nov 2007 00:18:37 +0000	[thread overview]
Message-ID: <20071114001837.27662.46685.stgit@warthog.procyon.org.uk> (raw)
In-Reply-To: <20071114001832.27662.8437.stgit@warthog.procyon.org.uk>

Move STACK_TOP[_MAX] out of asm/a.out.h and into asm/processor.h as they're
required whether or not A.OUT format is available.
