Add kstrtoul() to ../boot/ to be used by facilities there too. [ bp: Massage, make _kstrtoul() static. Prepend function names with "boot_". This is a temporary workaround for build errors like: ld: arch/x86/boot/compressed/acpi.o: in function `count_immovable_mem_regions': acpi.c:(.text+0x463): undefined reference to `_kstrtoul' make[2]: *** [arch/x86/boot/compressed/Makefile:117: arch/x86/boot/compressed/vmlinux] Error 1 due to the namespace clash between x86/boot/ and kernel proper. Future reorg will get rid of the linux/linux/ namespace as much as possible so that x86/boot/ can be independent from kernel proper. ] Signed-off-by: Vamshi K Sthambamkadi <vamshi.k.sthambamkadi@gmail.com> Signed-off-by: Borislav Petkov <bp@suse.de> Link: https://lkml.kernel.org/r/1587645588-7130-2-git-send-email-vamshi.k.sthambamkadi@gmail.com
