[Qemu-devel] [PATCH 16/35] Add qemu_ram_remap

From: Huang Ying qemu_ram_remap() unmaps the specified RAM pages, then re-maps these pages again. This is used by KVM HWPoison support to clear HWPoisoned page tables across guest rebooting, so that a new page may be allocated later to recover the memory error. [ Jan: style fixlets, WIN32 fix ]

[Qemu-devel] [PATCH 19/35] x86: Unbreak TCG support for hardware breakpoints

From: Jan Kiszka Commit 83f338f73e broke x86 hardware breakpoint emulation by moving the debug exception handling out of cpu_exec. Fix this by moving all TCG related bits back, only leaving the generic guest debugging parts in cpus.c. Signed-off-by: Jan Kiszka CC: TeLeMan Signed-off-by: Marcel
