* KVM: ia64: fix zero extending for mmio ld1/2/4 emulation in KVMJes Sorensen2008-06-061-1/+2
| | | | | | | | | | | Only copy in the data actually requested by the instruction emulation and zero pad the destination register first. This avoids the problem where emulated mmio access got garbled data from ld2.acq instructions in the vga console driver.

* KVM: ia64: fix GVMM module including position-dependent objectsXiantao Zhang2008-05-183-2/+3
| | | | | | | | | | | | | | | | | The GVMM module is position independent since it is relocated to the guest address space. Commit ea696f9cf ("ia64 kvm fixes for O=... builds") broke this by linking GVMM with non-PIC objects. Fix by creating two files: memset.S and memcpy.S which just include the files under arch/ia64/lib/{memset.S, memcpy.S} respectively. [akpm: don't delete files which we need] Signed-off-by: Xiantao Zhang <xiantao.zhang@intel.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Avi Kivity <avi@qumranet.com>
* rename div64_64 to div64_u64Roman Zippel2008-05-011-2/+1
| | | | | | | | | | | | | | | | | | | | | Rename div64_64 to div64_u64 to make it consistent with the other divide functions, so it clearly includes the type of the divide. Move its definition to math64.h as currently no architecture overrides the generic implementation. They can still override it of course, but the duplicated declarations are avoided.

* KVM: hlt emulation should take in-kernel APIC/PIT timers into accountMarcelo Tosatti2008-04-271-0/+5
| | | | | | | | | | | | | | | | | | Timers that fire between guest hlt and vcpu_block's add_wait_queue() are ignored, possibly resulting in hangs. Also make sure that atomic_inc and waitqueue_active tests happen in the specified order, otherwise the following race is open: CPU0 CPU1 if (waitqueue_active(wq)) add_wait_queue() if (!atomic_read(pit_timer->pending)) schedule() atomic_inc(pit_timer->pending) Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com> Signed-off-by: Avi Kivity <avi@qumranet.com>
