2009-10-16x86: Document linker script ASSERT() quirkIngo Molnar
Older binutils breaks if ASSERT() is used without a sink for the output. For example 2.14.90.0.6 is known to be broken, the link fails with: LD .tmp_vmlinux1 ld:arch/x86/kernel/vmlinux.lds:678: parse error Document this quirk in all three files that use it. See: http://marc.info/?l=linux-kbuild&m=124930110427870&w=2 See[2]: d2ba8b2 ("x86: Fix assert syntax in vmlinux.lds.S") Cc: Linus Torvalds <torvalds@linux-foundation.org> Cc: Roland McGrath <roland@redhat.com> Cc: "H.

2009-04-09x86, setup: "glove box" BIOS calls -- infrastructureH. Peter Anvin
Impact: new interfaces (not yet used) For all the platforms out there, there is an infinite number of buggy BIOSes. This adds infrastructure to treat BIOS interrupts more like toxic waste and "glove box" them -- we switch out the register set, perform the BIOS interrupt, and then restore the previous state.

2009-03-17x86, setup: move 32-bit code to .text32H. Peter Anvin
Impact: cleanup The setup code is mostly 16-bit code, but there is a small stub of 32-bit code at the end. Move the 32-bit code to a separate segment, .text32, to avoid scrambling the disassembly. Signed-off-by: H. Peter Anvin <hpa@linux.intel.com>
