2008-01-30x86 32-bit boot: rename bt_ioremap() to early_ioremap()Huang, Ying
This patch renames bt_ioremap to early_ioremap, which is used in x86_64. This makes it easier to merge i386 and x86_64 usage. [ mingo@elte.hu: fix ] Signed-off-by: Huang Ying <ying.huang@intel.com> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2008-01-30x86: replace boot_ioremap() with enhanced bt_ioremap() - remove boot_ioremap()Huang, Ying
This patch replaces boot_ioremap invokation with bt_ioremap and removes the boot_ioremap implementation. Signed-off-by: Huang Ying <ying.huang@intel.com> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2008-01-30i386 boot: replace boot_ioremap with enhanced bt_ioremap - enhance bt_ioremapHuang, Ying
This patch makes it possible for bt_ioremap() to be used before paging_init(), via providing an early implementation of set_fixmap() that can be used before paging_init(). This way boot_ioremap() can be replaced by bt_ioremap().

2008-01-30x86: set strong uncacheable where UC is really desiredSiddha, Suresh B
Also use _PAGE_PWT for all the mappings which need uncache mapping. Instead of existing PAT2 which is UC- (and can be overwritten by MTRRs), we now use PAT3 which is strong uncacheable. This makes it consistent with pgprot_noncached() Signed-off-by: Suresh Siddha <suresh.b.siddha@intel.com> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

2008-01-30x86: c_p_a(), add simple self test at bootAndi Kleen
Since change_page_attr() is tricky code it is good to have some regression test code. This patch maps and unmaps some random pages in the direct mapping at boot and then dumps the state and does some simple sanity checks. Add it with a CONFIG option.

2008-01-30x86: clean up pte_execAndi Kleen

2008-01-30x86: allocate and initialize unshared pmdsJeremy Fitzhardinge
If SHARED_KERNEL_PMD is false, then we need to allocate and initialize the kernel pmd. We can easily piggy-back this onto the existing pmd prepopulation code.

2008-01-30x86: preallocate pmds at pgd creation timeJeremy Fitzhardinge
In PAE mode, an update to the pgd requires a cr3 reload to make sure the processor notices the changes. Since this also has the side-effect of flushing the tlb, its an expensive operation which we want to avoid where possible. This patch mitigates the cost of installing the initial set of pmds on process creation by preallocating them when the pgd is allocated. This avoids up to three tlb flushes during exec, as it creates the new process address space while the pagetable is in active use. The pmds will be freed as part of the normal pagetable teardown in free_pgtables, which is called in munmap and process exit. However, free_pgtables will only free parts of the pagetable which actually contain mappings, so stray pmds may still be attached to the pgd at pgd_free time. We must mop them up to prevent a memory leak. Signed-off-by: Jeremy Fitzhardinge <jeremy@xensource.com> Cc: Andi Kleen <ak@suse.de> Cc: Linus Torvalds <torvalds@linux-foundation.org> Cc: H.

2008-01-30xen: deal with pmd being allocated/freedJeremy Fitzhardinge

2008-01-30x86: demacro asm-x86/pgalloc_32.hJeremy Fitzhardinge
Convert macros into inline functions, for better type-checking. This patch required a little bit of fiddling with headers in order to make __(pte|pmd)_free_tlb inline rather than macros. asm-generic/tlb.h includes asm/pgalloc.h, though it doesn't directly use any pgalloc definitions. I removed this include to avoid an include cycle, but it may cause secondary compile failures by things depending on the indirect inclusion; arch/x86/mm/hugetlbpage.c was one such place; there may be others.

2008-01-30x86: force enable HPET on (some?) ICH9 boardsAlistair John Strachan
Some consumer ICH9 boards (such as the Abit IP35 Pro) do not provide a BIOS option for enabling the HPET. The same ICH workaround used for 6,7,8 can be applied to 9. Here I enable the only PCI id that was visible on my system. I have confirmed the HPETs work both from userspace and as a clocksource for the running kernel (2.6.24 here) after applying this patch.

2008-01-30x86: fix usage of .section .sched.text in assembler codeSam Ravnborg
Without this patch the linker will generate a section named .sched.text.1 which is unexpected. This is because the gcc generated section has "ax" but the assembler usage of .sched.text lacks the "ax" specifier.
