Merge branch 'kbuild' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild
Pull kbuild changes from Michal Marek: - Alias generation in modpost is cross-compile safe. - kernel/timeconst.h is now generated using a bc script instead of perl. - scripts/link-vmlinux.sh now works with an alternative $KCONFIG_CONFIG. - destination-y for exported headers is supported in Kbuild files again. - depmod is called with -P $CONFIG_SYMBOL_PREFIX on architectures that need it. - CONFIG_DEBUG_INFO_REDUCED disables var-tracking - scripts/setlocalversion works with too much translated locales ;) * 'kbuild' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild: kbuild: Fix reading of .config in link-vmlinux.sh kbuild: Unset language specific variables in setlocalversion script Kbuild: Disable var tracking with CONFIG_DEBUG_INFO_REDUCED depmod: pass -P $CONFIG_SYMBOL_PREFIX kbuild: Fix destination-y for installed headers scripts/link-vmlinux.sh: source variables from KCONFIG_CONFIG kernel: Replace timeconst.pl with a bc script mod/file2alias: make modalias generation safe for cross compiling
