This reverts commit 34feb2c8. Suresh Siddha points out that this one breaks the fundamental requirement that you cannot free page table pages before the TLB caches are flushed. The quicklists do not give the same kinds of guarantees that the mmu_gather structure does, at least not in NUMA configurations.

This adds caching of pgds and puds, pmds, pte. That way we can avoid costly zeroing and initialization of special mappings in the pgd. A second quicklist is useful to separate out PGD handling. We can carry the initialized pgds over to the next process needing them. Also clean up the pgd_list handling to use regular list macros. There is no need anymore to avoid the lru field. Move the add/removal of the pgds to the pgdlist into the constructor / destructor. That way the implementation is congruent with i386.

x86_64 currently simulates a list using the index and private fields of the page struct. Seems that the code was inherited from i386. But x86_64 does not use the slab to allocate pgds and pmds etc. So the lru field is not used by the slab and therefore available. This patch uses standard list operations on page->lru to realize pgd tracking.

Move inclusion of asm/fixmap.h to where it is really used rather than where it may have been used long ago (requires a few other adjustments to includes due to previous implicit dependencies). Signed-off-by: NJan Beulich <jbeulich@novell.com> Signed-off-by: NAndi Kleen <ak@suse.de>

While the modular aspect of the respective i386 patch doesn't apply to x86-64 (as the top level page directory entry is shared between modules and the base kernel), handlers registered with register_die_notifier() are still under similar constraints for touching ioremap()ed or vmalloc()ed memory. The likelihood of this problem becoming visible is of course significantly lower, as the assigned virtual addresses would have to cross a 2**39 byte boundary. This is because the callback gets invoked (a) in the page fault path before the top level page table propagation gets carried out (hence a fault to propagate the top level page table entry/entries mapping to module's code/data would nest infinitly) and (b) in the NMI path, where nested faults must absolutely not happen, since otherwise the IRET from the nested fault re-enables NMIs, potentially resulting in nested NMI occurences.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
