This function is used in smp_send_stop(). It's like smp_call_function_mask, but always go to all online cpus, and does not take any locks. It is added to x86_64, but will soon be unified in a common file Signed-off-by: NGlauber Costa <gcosta@redhat.com> Signed-off-by: NIngo Molnar <mingo@elte.hu>

This patch creates smpcommon.c with functions that are equal between architectures. The i386-only init_gdt is ifdef'd. Note that smpcommon.o figures twice in the Makefile: this is because sub-architectures like voyager that does not use the normal smp_$(BITS) files also have to access them Signed-off-by: NGlauber Costa <gcosta@redhat.com> Signed-off-by: NIngo Molnar <mingo@elte.hu>

this patches moves prefill_possible_map() to smpboot.c Right now it is x86_64-specific, but nothing intrinsically prevents it to be used by i386 Signed-off-by: NGlauber Costa <gcosta@redhat.com> Signed-off-by: NIngo Molnar <mingo@elte.hu>

Jeremy Fitzhardinge pointed out that looking at the boot_params struct to determine if the system is running in a paravirtual environment is not reliable for the Xen case, currently. He also points out that there already exists a function to determine if the system is running in a paravirtual environment. So let's use that instead. This gets rid of the preprocessor test too.

The current tsc_init() clears the TSC feature bit if the TSC khz cannot be calculated, causing us to panic in arch/x86/kernel/cpu/bugs.c check_config(). We should simply mark it unstable. Frankly, someone should take an axe to this code. mark_tsc_unstable() not only marks it unstable, but sets tsc_enabled to 0, which seems redundant but is actually important here because means it won't be used by sched_clock() either. Perhaps a tristate enum "UNUSABLE, UNSTABLE, OK" would be clearer, and separate mark_tsc_unstable() and mark_tsc_broken() functions?

This patch is an add-on to the 64-bit ebda patch. It makes the functions reserve_ebda_region (renamed from reserve_ebda) and copy_e820_map equal to the 32-bit versions of the previous patch. Changes: Use u64 and u32 for local variables in copy_e820_map. The amount of conventional memory and the start of the EBDA are detected by reading the BIOS data area directly. Paravirtual environments do not provide this area, so we bail out early in that case. They will just have to set up a correct memory map to start with. Add a safety net for zeroed out BIOS data area.

Explicitly reserve_early the whole address range from the end of conventional memory as reported by the bios data area up to the 1Mb mark. Regard the info retrieved from the BIOS data area with a bit of paranoia, though, because some biosses forget to register the EBDA correctly.

This patch adds explicit detection of the EBDA and reservation of the rom and adapter address space 0xa0000-0x100000 to the i386 kernels. Before this patch, the EBDA size was hardcoded as 4Kb. Also, the reservation of the adapter range was done by modifying the e820 map which is now not necessary any longer, and that code is removed from copy_e820_map. The amount of conventional memory and the start of the EBDA are detected by reading the BIOS data area directly. Paravirtual environments do not provide this area, so we bail out early in that case. They will just have to set up a correct memory map to start with. Signed-off-by: NAlexander van Heukelum <heukelum@fastmail.fm> Signed-off-by: NIngo Molnar <mingo@elte.hu>
