When FSGSBASE is enabled, the GSBASE handling in paranoid entry will need to retrieve the kernel GSBASE which requires that the kernel page table is active. As the CR3 switch to the kernel page tables (PTI is active) does not depend on kernel GSBASE, move the CR3 switch in front of the GSBASE handling. Comment the EBX content while at it. No functional change. [ tglx: Rewrote changelog and comments ] Signed-off-by:
