* KVM: fix the handling of dirty bitmaps to avoid overflowsTakuya Yoshikawa2010-04-26
| | | | | | | | | | | | | | | | | (Cherry-picked from commit 87bf6e7de1134f48681fd2ce4b7c1ec45458cb6d) Int is not long enough to store the size of a dirty bitmap. This patch fixes this problem with the introduction of a wrapper function to calculate the sizes of dirty bitmaps. Note: in mark_page_dirty(), we have to consider the fact that __set_bit() takes the offset as int, not long.

* powerpc/kvm: Sync guest visible MMU stateAlexander Graf2009-12-08
| | | | | | | | | | | | | Currently userspace has no chance to find out which virtual address space we're in and resolve addresses. While that is a big problem for migration, it's also unpleasent when debugging, as gdb and the monitor don't work on virtual addresses. This patch exports enough of the MMU segment state to userspace to make debugging work and thus also includes the groundwork for migration.

* Add book3s.cAlexander Graf2009-11-05
This adds the book3s core handling file. Here everything that is generic to desktop PowerPC cores is handled, including interrupt injections, MSR settings, etc. It basically takes over the same role as booke.c for embedded PowerPCs.
