Ingo Molnar	ebd9026d9f	stackprotector: fix multi-word cross-builds ... Stackprotector builds were failing if CROSS_COMPILER was more than a single world (such as when distcc was used) - because the check scripts used $1 instead of $*.

Tejun Heo	5d707e9c8e	stackprotector: update make rules ... Impact: no default -fno-stack-protector if stackp is enabled, cleanup Stackprotector make rules had the following problems. * cc support test and warning are scattered across makefile and kernel/panic.c. * -fno-stack-protector was always added regardless of configuration. Update such that cc support test and warning are contained in makefile and -fno-stack-protector is added iff stackp is turned off. While at it, prepare for 32bit support.

Arjan van de Ven	4f7fd4d7a7	[PATCH] Add the -fstack-protector option to the CFLAGS ... Add a feature check that checks that the gcc compiler has stack-protector support and has the bugfix for PR28281 to make this work in kernel mode. The easiest solution I could find was to have a shell script in scripts/ to do the detection; if needed we can make this fancier in the future without making the makefile too complex.
