#     Pull Kbuild updates from Masahiro Yamada:
#     
#      - Fix false-positive build warnings for ARCH=ia64 builds
#     
#      - Optimize dictionary size for module compression with xz
#     
#      - Check the compiler and linker versions in Kconfig
#     
#      - Fix misuse of extra-y
#     
#      - Support DWARF v5 debug info
#     
#      - Clamp SUBLEVEL to 255 because stable releases 4.4.x and 4.9.x
#        exceeded the limit
#     
#      - Add generic syscall{tbl,hdr}.sh for cleanups across arches
#
