History
Stanislav Sedov b2d758545b - Add support to atomically set/clear individual bits of a MSR register 
via cpuctl(4) driver.  Two new CPUCTL_MSRSBIT and CPUCTL_MSRCBIT ioctl(2)
  calls treat the data field of the argument struct passed as a mask
  and set/clear bits of the MSR register according to the mask value.
- Allow user to perform atomic bitwise AND and OR operaions on MSR registers
  via cpucontrol(8) utility.  Two new operations ("&=" and "|=") have been
  added.  The first one applies bitwise AND operaion between the current
  contents of the MSR register and the mask, and the second performs bitwise
  OR.  The argument can be optionally prefixed with "~" inversion operator.
  This allows one to mimic the "clear bit" behavior by using the command
  like this:
      cpucontrol -m 0x10&=~0x02		# clear the second bit of TSC MSR

  Inversion operator support in all modes (assignment, OR, AND).
