H. Peter Anvin	1371270188	x86, realmode: Move kernel/realmode.c to realmode/init.c ... Keep all the realmode code together, including initialization (only the rm/ subdirectory is actually built as real-mode code, anyway.) Signed-off-by: H.

Jarkko Sakkinen	c5403aed04	x86, realmode: build fix: remove duplicate build ... Real-mode binary was built twice. This patch fixes the issue by making realmode.relocs as target for realmode.bin. [ hpa: removed the direct dependency on realmode.relocs in arch/x86/realmode/Makefile ] Signed-off-by: Jarkko Sakkinen <jarkko.sakkinen@intel.com> Link: http://lkml.kernel.org/r/1336595106-21135-1-git-send-email-jarkko.sakkinen@intel.com Cc: Sam Ravnborg <sam@ravnborg.org> Cc: Michal Marek <mmarek@suse.cz> Signed-off-by: H.

Jarkko Sakkinen	b3266bd6ff	x86, realmode: realmode.bin infrastructure ... Create realmode.bin and realmode.relocs files. Piggy pack them into relocatable object that will be included into .init.data section of the main kernel image. The first file includes binary image of the real-mode code. The latter file includes all relocations. The layout of the binary image is specified in realmode.lds.S. The makefile generates pa_ prefixed symbols for each exported global. These are used in 32-bit code and in realmode header to define symbols that need to be relocated.
