* x86: uaccess: introduce try and catch frameworkHiroshi Shimamoto2009-01-232-0/+104
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Impact: introduce new uaccess exception handling framework Introduce {get|put}_user_try and {get|put}_user_catch as new uaccess exception handling framework. {get|put}_user_try begins exception block and {get|put}_user_catch(err) ends the block and gets err if an exception occured in {get|put}_user_ex() in the block. The exception is stored thread_info->uaccess_err. The example usage of this framework is below; int func() { int err = 0; get_user_try { get_user_ex(...); get_user_ex(...); : } get_user_catch(err); return err; } Note: get_user_ex() is not clear the value when an exception occurs, it's different from the behavior of __get_user(), but I think it doesn't matter.

* x86: remove byte locksJiri Kosina2009-01-202-66/+2
| | | | | | | | | | | | | Impact: cleanup Remove byte locks implementation, which was introduced by Jeremy in 8efcbab6 ("paravirt: introduce a "lock-byte" spinlock implementation"), but turned out to be dead code that is not used by any in-kernel virtualization guest (Xen uses its own variant of spinlocks implementation and KVM is not planning to move to byte locks).
