Merge branch 'rc-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild
Pull kbuild fixes from Michal Marek: "Here are some regression fixes for kbuild: - modversion support for exported asm symbols (Nick Piggin). The affected architectures need separate patches adding asm-prototypes.h. - fix rebuilds of lib-ksyms.o (Nick Piggin) - -fno-PIE builds (Sebastian Siewior and Borislav Petkov). This is not a kernel regression, but one of the Debian gcc package. Nevertheless, it's quite annoying, so I think it should go into mainline and stable now" * 'rc-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild: kbuild: Steal gcc's pie from the very beginning kbuild: be more careful about matching preprocessed asm ___EXPORT_SYMBOL x86/kexec: add -fno-PIE scripts/has-stack-protector: add -fno-PIE kbuild: add -fno-PIE kbuild: modversions for EXPORT_SYMBOL() for asm kbuild: prevent lib-ksyms.o rebuilds
