Now that the only user does it on its own remove the NUMAQ support macros in io_32.h The next step would be to convert the preprocessor mess to actually readable standard inlines. Signed-off-by:

numa.c is the only user of the {in,out}*_quad functions. And it has only a few call sites. Change them to open code the magic NUMAQ port access. Signed-off-by: -

This patch eliminates numbers in LDT allocation code trying to make it clear to understand from where these numbers come. No code changed: text data bss dec hex filename 1896 0 0 1896 768 ldt.o.before 1896 0 0 1896 768 ldt.o.after md5: 6cbec8705008ddb4b704aade60bceda3 ldt.o.before.asm 6cbec8705008ddb4b704aade60bceda3 ldt.o.after.asm Signed-off-by:

Remove bogus reference to "Pentium-II erratum A13" and point to the actual canonical source of information about what requirements x86 processors have for PAE pagetable updates. Signed-off-by:

Rather than unconditionally reloading cr3, only do so if the pud we're updating is within the active pgd. This eliminates TLB flushes most of the time. The performance-critical uses of pud_clear are during execve and exit, but in those cases cr3 is referring to some other pagetable. The only other use of pud_clear is during a large (1Gbyte+) munmap, and those are sufficiently rare that a couple of cr3 reloads won't hurt. Signed-off-by:

Revert "defer cr3 reload when doing pud_clear()" since I'm going to replace it. Signed-off-by:

The constructors for PAE and non-PAE pgd_ctors are more or less identical, and can be made into the same function. Signed-off-by:

cyrix_arr_init was #if 0 all the way back to at least v2.6.12. This was the only place where arr3_protected was set to anything but zero. Eliminate this variable. Signed-off-by:

Instead of obscure numbers, print the list of missing CPU features in cleartext. To conserve space, use a host program (mkcpustr.c) to produce a compact list of mandatory features only. Signed-off-by:

Move the CPU feature string names to a separate file (common to 32 and 64 bits); additionally, make <asm/cpufeature.h> includable by host code in preparation for including the CPU feature strings in the boot code. Signed-off-by:

The volatile keyword was removed from the clflush() prototype in commit e34907ae; the comment there states: x86: remove volatile keyword from clflush. the p parameter is an explicit memory reference, and is enough to prevent gcc to being nasty here. The volatile seems completely not needed. This reflects incorrect understanding of the function of the volatile keyword there. The purpose of the volatile keyword is informing gcc that it is safe to pass a volatile pointer to this function. Signed-off-by:

After /dev/*/cpuid was introduced, Intel changed the semantics of the CPUID instruction to be sentitive to %ecx as well as %eax. This patch allows querying of %ecx-sensitive levels by placing the %ecx value in the upper 32 bits of the file position (lower 32 bits always were used for the %eax value.) Signed-off-by:

The module scx200 were renamed to scx200_32 by the merge of the 32 and 64 bit x86 arch trees. Keep the _32 prefix on the .c file as it is 32 bit specific and fix the module name in the Makefile. Signed-off-by:

The apm module were renamed to apm_32 during the merge of 32 and 64 bit x86 which is unfortunate. As apm is 32 bit specific we like to keep the _32 in the filename but the module should be named apm. Fix this in the Makefile. Reported-by:
