| |
2.6.27-stable review patch. If anyone has any objections, please let us know.
------------------ From: Linus Torvalds <torvalds@linux-foundation.org>
commit d0115552cdb0b4d4146975889fee2e9355515c4b upstream.
Sam Ravnborg says: "We have several architectures that plays strange games with $(CC) and $(CROSS_COMPILE).
So we need to postpone any use of $(call cc-option..) until we have included the arch specific Makefile so we try with the correct $(CC) version."
