Linus Torvalds 3f0d6ecdf1 Generic implementation of common syscall, interrupt and exception 
entry/exit functionality based on the recent X86 effort to ensure
 correctness of entry/exit vs. RCU and instrumentation.
 
 As this functionality and the required entry/exit sequences are not
 architecture specific, sharing them allows other architectures to benefit
 instead of copying the same code over and over again.
 
 This branch was kept standalone to allow others to work on it. The
 conversion of x86 comes in a seperate pull request which obviously is based
 on this branch.
