2008-10-10[S390] introduce dirty bit for kvm live migrationFlorian Funke
This patch defines a dirty bit in the PGSTE that can be used to implement dirty pages logging for KVM's live migration. The bit is set in the ptep_rcp_copy function, which is called to save dirty and referenced information from the storage key in the PGSTE. The bit can be tested and reset by KVM using the kvm_s390_test_and_clear_page_dirty function that is introduced by this patch.

Instead of making init a two pass sequence, to satisfy the Intel's TLB Application note (developer.intel.com/design/processor/applnots/317080.pdf Section 6 page 26), we preserve the original page permissions when fragmenting the large mappings and don't touch the existing memory mapping (which satisfies Xen's requirements). Only open issue is: on a native linux kernel, we will go back to mapping the first 0-1GB kernel identity mapping as executable (because of the static mapping setup in head_64.S). We can fix this in a different patch if needed. Signed-off-by: Suresh Siddha <suresh.b.siddha@intel.com> Acked-by: Jeremy Fitzhardinge <jeremy@goop.org> Signed-off-by: Ingo Molnar <mingo@elte.hu>

2008-10-10x86: track memtype for RAM in page structSuresh Siddha
Track the memtype for RAM pages in page struct instead of using the memtype list. This avoids the explosion in the number of entries in memtype list (of the order of 20,000 with AGP) and makes the PAT tracking simpler. We are using PG_arch_1 bit in page->flags. We still use the memtype list for non RAM pages.

2008-10-10x86, cpa: srlz cpa(), global flush tlb after splitting big page and before ↵Suresh Siddha
doing cpa Do a global flush tlb after splitting the large page and before we do the actual change page attribute in the PTE. With out this, we violate the TLB application note, which says "The TLBs may contain both ordinary and large-page translations for a 4-KByte range of linear addresses. This may occur if software modifies the paging structures so that the page size used for the address range changes. If the two translations differ with respect to page frame or attributes (e.g., permissions), processor behavior is undefined and may be implementation-specific." And also serialize cpa() (for !DEBUG_PAGEALLOC which uses large identity mappings) using cpa_lock. So that we don't allow any other cpu, with stale large tlb entries change the page attribute in parallel to some other cpu splitting a large page entry along with changing the attribute.

No alias checking needed for setting present/not-present mapping. Otherwise, we may need to break large pages for 64-bit kernel text mappings (this adds to complexity if we want to do this from atomic context especially, for ex: with CONFIG_DEBUG_PAGEALLOC).

Don't use large pages for kernel identity mapping with DEBUG_PAGEALLOC. This will remove the need to split the large page for the allocated kernel page in the interrupt context. This will simplify cpa code(as we don't do the split any more from the interrupt context). cpa code simplication in the subsequent patches.

2008-10-10x86, cpa: make the kernel physical mapping initialization a two pass sequenceSuresh Siddha
In the first pass, kernel physical mapping will be setup using large or small pages but uses the same PTE attributes as that of the early PTE attributes setup by early boot code in head_[32|64].S After flushing TLB's, we go through the second pass, which setups the direct mapped PTE's with the appropriate attributes (like NX, GLOBAL etc) which are runtime detectable. This two pass mechanism conforms to the TLB app note which says: "Software should not write to a paging-structure entry in a way that would change, for any linear address, both the page size and either the page frame or attributes."
