    Linus Torvalds authored
    Pull Kbuild updates from Masahiro Yamada:
    
     - fix warnings in 'make clean' for ARCH=um, hexagon, h8300, unicore32
    
     - ensure to rebuild all objects when the compiler is upgraded
    
     - exclude system headers from dependency tracking and fixdep processing
    
     - fix potential bit-size mismatch between the kernel and BPF user-mode
       helper
    
     - add the new syntax 'userprogs' to build user-space programs for the
       target architecture (the same arch as the kernel)
    
     - compile user-space sample code under samples/ for the target arch
       instead of the host arch
    
     - make headers_install fail if a CONFIG option is leaked to user-space
    
     - sanitize the output format of scripts/checkstack.pl
    
     - handle ARM 'push' instruction in scripts/checkstack.pl
    
     - error out before modpost if a module name conflict is found
    
     - error out when multiple directories are passed to M= because this
       feature is broken for a long time
    
     - add CONFIG_DEBUG_INFO_COMPRESSED to support compressed debug info
    
     - a lot of cleanups of modpost
    
     - dump vmlinux symbols out into vmlinux.symvers, and reuse it in the
       second pass of modpost
    
     - do not run the second pass of modpost if nothing in modules is
       updated
    
     - install modules.builtin(.modinfo) by 'make install' as well as by
       'make modules_install' because it is useful even when
       CONFIG_MODULES=n
    
     - add new command line variables, GZIP, BZIP2, LZOP, LZMA, LZ4, and XZ
       to allow users to use alternatives such as pigz, pbzip2, etc.
