2009-03-19x86: with the last user gone, remove set_pte_presentJeremy Fitzhardinge
Impact: cleanup set_pte_present() is no longer used, directly or indirectly, so remove it.

2009-02-24x86: update populate_extra_pte() and add populate_extra_pmd()Tejun Heo
Impact: minor change to populate_extra_pte() and addition of pmd flavor Update populate_extra_pte() to return pointer to the pte_t for the specified address and add populate_extra_pmd() which only populates till the pmd and returns pointer to the pmd entry for the address. For 64bit, pud/pmd/pte fill functions are separated out from set_pte_vaddr[_pud]() and used for set_pte_vaddr[_pud]() and populate_extra_{pte|pmd}(). Signed-off-by: Tejun Heo <tj@kernel.org>
2009-02-20x86: convert to the new dynamic percpu allocatorTejun Heo
Impact: use new dynamic allocator, unified access to static/dynamic percpu memory Convert to the new dynamic percpu allocator. * implement populate_extra_pte() for both 32 and 64 * update setup_per_cpu_areas() to use pcpu_setup_static() * define __addr_to_pcpu_ptr() and __pcpu_ptr_to_addr() * define config HAVE_DYNAMIC_PER_CPU_AREA Signed-off-by: Tejun Heo <tj@kernel.org>

2009-02-06x86: make pgd/pud/pmd/pte_none consistentJeremy Fitzhardinge
The _none test is done differently for every level of the pagetable. Standardize them by: 1: Use the native_X_val to extract the raw entry, with no need to go via paravirt_ops, diff -r 1d0646d0d319 arch/x86/include/asm/pgtable.h, and 2: Compare with 0 rather than using a boolean !, since they are actually values and not booleans.

2009-02-04x86: don't apply __supported_pte_mask to non-present ptesJeremy Fitzhardinge
On an x86 system which doesn't support global mappings, __supported_pte_mask has _PAGE_GLOBAL clear, to make sure it never appears in the PTE. pfn_pte() and so on will enforce it with: static inline pte_t pfn_pte(unsigned long page_nr, pgprot_t pgprot) { return __pte((((phys_addr_t)page_nr << PAGE_SHIFT) | pgprot_val(pgprot)) & __supported_pte_mask); } However, we overload _PAGE_GLOBAL with _PAGE_PROTNONE on non-present ptes to distinguish them from swap entries. However, applying __supported_pte_mask indiscriminately will clear the bit and corrupt the pte. I guess the best fix is to only apply __supported_pte_mask to present ptes. This seems like the right solution to me, as it means we can completely ignore the issue of overlaps between the present pte bits and the non-present pte-as-swap entry use of the bits. __supported_pte_mask contains the set of flags we support on the current hardware. We also use bits in the pte for things like logically present ptes with no permissions, and swap entries for swapped out pages. We should only apply __supported_pte_mask to present ptes, because otherwise we may destroy other information being stored in the ptes.

2009-01-22x86: add pte_set_flags/clear_flags for pte flag manipulationJeremy Fitzhardinge
It's not necessary to deconstruct and reconstruct a pte every time its flags are being updated. Introduce pte_set_flags and pte_clear_flags to set and clear flags in a pte. This allows the flag manipulation code to be inlined, and avoids calls via paravirt-ops. Signed-off-by: Jeremy Fitzhardinge <jeremy.fitzhardinge@citrix.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
