DEBUG_PAGEALLOC was not possible on 64-bit due to its early-bootup hardcoded reliance on PSE pages, and the unrobustness of the runtime splitup of large pages. The splitup ended in recursive calls to alloc_pages() when a page for a pte split was requested. Avoid the recursion with a preallocated page pool, which is used to split up large mappings and gets refilled in the return path of kernel_map_pages after the split has been done. The size of the page pool is adjusted to the available memory. This part just implements the page pool and the initialization w/o using it yet. Signed-off-by:

Beginning from commit 4138cc34, ioremap_nocache() sets the _PAGE_PWT flag. Lguest doesn't accept a guest pte with a _PWT flag and reports a "bad page table entry" in that case. Accept guest _PAGE_PWT page table entries. Signed-off-by:

In arch/x86/boot/printf.c gets rid of unused tail of digits: const char *digits = "0123456789abcdefghijklmnopqrstuvwxyz"; (we are using 0-9a-f only) Uses smaller/faster lowercasing (by ORing with 0x20) if we know that we work on numbers/digits. Makes strtoul smaller, and also we are getting rid of static const char small_digits[] = "0123456789abcdefx"; static const char large_digits[] = "0123456789ABCDEFX"; since this works equally well: static const char digits[16] = "0123456789ABCDEF"; Size savings: $ size vmlinux.org vmlinux text data bss dec hex filename 877320 112252 90112 1079684 107984 vmlinux.org 877048 112252 90112 1079412 107874 vmlinux It may be also a tiny bit faster because code has less branches now, but I doubt it is measurable.

Specifically the boot time page tables in a CONFIG_X86_PAE=y enabled kernel are in PAE format. early_ioremap is updated to use the standard page table accessors. Clear any mappings beyond max_low_pfn from the boot page tables in native_pagetable_setup_start because the initial mappings can extend beyond the range of physical memory and into the vmalloc area.

Add function definition and extern variables to asm-x86/acpi.h. All of these are used in bus.c in ifdef(CONFIG_X86) sections, so are only added to the x86 include headers. boot.c already includes acpi.h so no changes are needed there.

Each AMD Geode MFGPT timer interrupt output is paired with another timer; esentially the interrupt goes if either timer fires. This is okay, but the handlers need to be aware of this. Make sure in the timer tick handler that our timer really did expire. Signed-off-by:

We *really* don't want to be reading MFGPTx_SETUP and writing back those values. What we want to be doing is clearing CMP1 and CMP2 unconditionally; otherwise, we have races where CMP1 and/or CMP2 fire after we've read MFGPTx_SETUP. They can also fire between when we've written ~CNTEN to the register, and when the new register values get copied to the timer's version of the register. By clearing both fields, we're okay.

There isn't much value to always detecting the MFGPT timers on Geode platforms; detection is only needed when something wants to use the timers. Move the detection code so that it gets called the first time a timer is allocated. Signed-off-by:

We had planned to use the 'owner' field for allowing re-allocation of MFGPTs; however, doing it by module owner name isn't flexible enough. So, drop this for now. If it turns out that we need timers in modules, we'll need to come up with a scheme that matches the write-once fields of the MFGPTx_SETUP register, and drops ponies from the sky. Signed-off-by:

The GEODE MFGPT code assumed that 32kHz was 32000 Hz while the boards run on a 32.768 kHz digital watch crystal. In practise, it will not change the timer's frequency as the skew was only 2.4%, but it should provide more accurate intervals. Signed-off-by:

mm_cgroup() is exclusively used to test whether an mm's mem_cgroup pointer is pointing to a specific cgroup. Instead of returning the pointer, we can just do the test itself in a new macro: vm_match_cgroup(mm, cgroup) returns non-zero if the mm's mem_cgroup points to cgroup. Otherwise it returns zero.
