move the trampoline setup code out of smpboot.c - UP kernels can have suspend support too. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-04-17x86: move suspend wakeup code to CPavel Machek
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.

2008-04-17x86: setup_trampoline() - fix section mismatch warningJacek Luczak
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.

This patch fixes mismatch warnings in smp_checks() (in arch/x86/kernel/smpboot.c): WARNING: arch/x86/kernel/built-in.o(.text+0x11922): Section mismatch in reference from the function smp_checks() to the variable .cpuinit.data:smp_b_stepping The function smp_checks() references the variable __cpuinitdata smp_b_stepping. This is often because smp_checks lacks a __cpuinitdata annotation or the annotation of smp_b_stepping is wrong.

The shutdown status flag set to "0xA", corresponds to "JMP double word request without INT init". This JMP at reboot time is at an unintended location. And results in Triple faults in our case. Though this error at reboot can be safely ignored in a VM environment, am not sure what the effect would be on a physical system. May be it will result in a triple fault and an eventual hardware reset thus masking this BUG in the kernel. This fix just makes sure that we reset that status flag after initialization is done. Fix paranoia about using BIOS quickboot mechanism. Make sure that we clear the "shutdown status flag" in the CMOS register after each CPU is brought up. This fixes a problem where the "shutdown status flag" may remain set when a CPU is brought up after booting.

2008-04-17x86: remove superfluous initialisation in boot code.Alexander van Heukelum
In arch/x86/boot/compressed/misc.c, the variable vidmem is the only variable that ends up in de data segment. It's also superfluous, because the first thing the code does is: if (RM_SCREEN_INFO.orig_video_mode == 7) { vidmem = (char *) 0xb0000; vidport = 0x3b4; } else { vidmem = (char *) 0xb8000; vidport = 0x3d4; } This patch removes the initialisation.

2008-04-17x86: MPSC should use P6 NOPsHugh Dickins
I've now noticed that the machine I call MPENTIUM4 for 32-bit kernels is called MPSC for 64-bit kernels, and in that case it still doesn't get the P6 NOPs it ought to. hpa explains that MK8 should still be excluded, so it's just a matter of including MPSC along with MPENTIUM4.
