Modified files:
sys/i386/include cpufunc.h
Log:
Rev 1.132 was backed out because of the following from BDE:
By returning garbage for the unused high bits of segment registers, we
avoid wasting time initializing the bits if the results are assigned to
32-bit variables. movl instead of movw was also intentional, to
prevent gas adding pessimal pessimal segment overrides.
See src-committers Message-ID: <20030419173421.N15436@gamplex.bde.org>, for
more details and how to optimize this farther.
