bitkeeper revision 1.1733 (42ba827d4k5gz1Dasgd0gorMu-SSmQ)
The 32-bit x86 LTP exposed bugs with LDT handling with x86_64 Xen and
XenLinux:
- fill the code for arbitrary_virt_to_machine(XenLinux)
- set 64-bit value for the base address for LDT (Xen)
- fix a bug (64-bit cleanup) in map_ldt_shadow_page (Xen)
