This patchset enables masking the reception of write_ctrlreg events depending
on the value of certain bits in that register.
The most representative example is filtering out events when the CR4.PGE
bit is being flipped (global TLB flushes)

* fix coding style
* use ARRAY_SIZE and named indexes for x86 ctrl register resolution
