Routine Description:
Used to read data from the current processor's KPCR. This is a support
function for KPCR_READ_FIELD
Arguments:
Offset - Supplies the offset within the KPCR to begin the read
Length - Supplies the length of the data to read from the KPCR. Must
be one of 1, 2, 4 or 8.
Buffer - Supplies the target buffer that contains the data to read from
the KPCR.
Return value:
None
