X-Git-Tag: omap-for-v3.17/fixes-against-rc2~268^2~2^2
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=c7fb93ec51d462ec3540a729ba446663c26a0505;p=pandora-kernel.git

x86/efi: Include a .bss section within the PE/COFF headers

The PE/COFF headers currently describe only the initialised-data
portions of the image, and result in no space being allocated for the
uninitialised-data portions.  Consequently, the EFI boot stub will end
up overwriting unexpected areas of memory, with unpredictable results.

Fix by including a .bss section in the PE/COFF headers (functionally
equivalent to the init_size field in the bzImage header).
