2009-10-12	x86: Fix Suspend to RAM freeze on Acer Aspire 1511Lmi laptop	Jan Beulich	1	-0/+4
	Move the trampoline and accessors back out of .cpuinit.* for the case of 64-bits+ACPI_SLEEP. This solves s2ram hangs reported in: http://bugzilla.kernel.org/show_bug.cgi?id=14279 Reported-and-bisected-by: Christian Casteyde <casteyde.christian@free.fr> Signed-off-by: Jan Beulich <jbeulich@novell.com> Cc: <bugzilla-daemon@bugzilla.kernel.org> Cc: "Andrew Morton" <akpm@linux-foundation.org> Cc: "Rafael J.

2009-09-20	x86: cpuinit-annotate SMP boot trampolines properly	Jan Beulich	1	-2/+3
	Add missing annotations, and make use of include/linux/init.h's macros. Signed-off-by: Jan Beulich <jbeulich@novell.com> LKML-Reference: <4AA0E8F60200007800013703@vpn.id2.novell.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-02-13	x86: use _types.h headers in asm where available	Jeremy Fitzhardinge	1	-2/+2
	In general, the only definitions that assembly files can use are in _types.S headers (where available), so convert them. Signed-off-by: Jeremy Fitzhardinge <jeremy.fitzhardinge@citrix.com>
2009-01-29	x86: trampoline_64.S - use predefined constants with simplification	Cyrill Gorcunov	1	-10/+9
	Impact: cleanup We may use macros from processor-flags.h instead of hardcoding bits. Actually it's not direct mapping of old instructions with new ones -- BTS does change CF flag while MOV does not. But i didn't find any dependency on CF in this code.

2008-04-17	x86: move suspend wakeup code to C	Pavel Machek	1	-5/+0
	Move wakeup code to .c, so that video mode setting code can be shared between boot and wakeup. Remove nasty assembly code in 64-bit case by re-using trampoline code. Stack setup was fixed to clear high 16bits of %esp, maybe that fixes some machines. .c code sharing and morse code was done H. Peter Anvin, Sam Ravnborg reviewed kbuild related stuff, and it seems okay to him. Rafael did some cleanups. [rjw: * Made the patch stop breaking compilation on x86-32 * Added arch/x86/kernel/acpi/sleep.h * Got rid of compiler warnings in arch/x86/kernel/acpi/sleep.c * Fixed 32-bit compilation on x86-64 systems * Added include/asm-x86/trampoline.h and fixed the non-SMP compilation on 64-bit x86 * Removed arch/x86/kernel/acpi/sleep_32.c which was not used * Fixed some breakage caused by the integration of smpboot.c done under us in the meantime] Signed-off-by: Pavel Machek <pavel@suse.cz> Signed-off-by: H.

2008-04-17	x86: setup_trampoline() - fix section mismatch warning	Jacek Luczak	1	-1/+1
	this patch fixes section mismatch warnings (on x86_64 host) in setup_trampoline(), which was referencing __initdata variables trampoline_data and trampoline_end. Warning messages: WARNING: arch/x86/kernel/built-in.o(.cpuinit.text+0x2b6a): Section mismatch in reference from the function setup_trampoline() to the variable .init.data:trampoline_data The function __cpuinit setup_trampoline() references a variable __initdata trampoline_data. If trampoline_data is only used by setup_trampoline then annotate trampoline_data with a matching annotation. WARNING: arch/x86/kernel/built-in.o(.cpuinit.text+0x2b71): Section mismatch in reference from the function setup_trampoline() to the variable .init.data:trampoline_end The function __cpuinit setup_trampoline() references a variable __initdata trampoline_end. If trampoline_end is only used by setup_trampoline then annotate trampoline_end with a matching annotation. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-02-04	x86: remove misleading comments in trampoline_*.S	Pavel Machek	1	-3/+0
