In order to work around old LILO versions providing an invalid ss register, the current setup code always sets up a new stack, immediately following .bss and the heap. But this breaks LOADLIN. This rewrite of the workaround checks for an invalid stack (ss!=ds) first, and leaves ss:sp alone otherwise (apart from aligning esp). [hpa note: LOADLIN has a number of arbitrary hard-coded limits that are being pushed up against. Without some major revision of LOADLIN itself it will not be sustainable keeping it alive. This gives it another brief lease on life, however. This patch also helps the cmdline truncation problem with old versions of SYSLINUX.] Signed-off-by: Jens Rottmann <JRottmann at LiPPERT-AT. de> Signed-off-by: H. Peter Anvin <hpa@zytor.com> |
