remove mca-pentium

2008-02-19T15:18:28+00:00

This patch removes the mca-pentium boot option that was a noop.

besides the source code cleanup factor, this saves some text as well:

      text    data     bss     dec     hex filename

aout: move STACK_TOP[_MAX] to asm/processor.h

2008-02-08T17:22:29+00:00

Move STACK_TOP[_MAX] out of asm/a.out.h and into asm/processor.h as they're
required whether or not A.OUT format is available.

x86: add framework to disable CPUID bits on the command line

2008-01-30T12:33:20+00:00

There are already various options to disable specific cpuid bits
on the command line. They all use their own variable. Add a generic
mask to make this easier in the future.

x86: change size of APICIDs from u8 to u16

2008-01-30T12:33:10+00:00

Change the size of APICIDs from u8 to u16.  This partially
supports the new x2apic mode that will be present on future
processor chips. (Chips actually support 32-bit APICIDs, but that
change is more intrusive. Supporting 16-bit is sufficient for now).

Signed-off-by: Jack Steiner 

I've included just the partial change from u8 to u16 apicids.  The
remaining x2apic changes will be in a separate patch.

In addition, the fake_node_to_pxm_map[] and fake_apicid_to_node[]
tables have been moved from local data to the __initdata section
reducing stack pressure when MAX_NUMNODES and MAX_LOCAL_APIC are
increased in size.

x86: page.h: make pte_t a union to always include

2008-01-30T12:32:57+00:00

Make sure pte_t, whatever its definition, has a pte element with type
pteval_t.  This allows common code to access it without needing to be
specifically parameterised on what pagetable mode we're compiling for.
For 32-bit, this means that pte_t becomes a union with "pte" and "{
pte_low, pte_high }" (PAE) or just "pte_low" (non-PAE).

x86: move nop declarations into separate include file

2008-01-30T12:32:38+00:00

Moving things out of processor.h is always a good thing.

Also needed to avoid include loop in later patch.

operation in x86_64.

x86: finish processor.h integration

2008-01-30T12:31:57+00:00

What's left in processor_32.h and processor_64.h cannot be cleanly
integrated. However, it's just a couple of definitions. They are moved
to processor.h around ifdefs, and the original files are deleted. Note that
there's much less headers included in the final version.
