[PATCH] hvf: Fix segment selector format


From: Jessica Clarke
Subject: [PATCH] hvf: Fix segment selector format
Date: Mon, 16 Nov 2020 20:04:14 +0000

The Requested Privilege Level field is 2 bits, the Table Indicator field
is 1 bit and the Index field is the remaining 15 bits, with TI=0 meaning
GDT and TI=1 meaning LDT.
