The BUILD_BUG_ON(IO_BITMAP_OFFSET - 1 == 0x67) in the VMX code is bogus in
two aspects:
1) This wants to be in generic x86 code simply to catch issues even when
VMX is disabled in Kconfig.
2) The IO_BITMAP_OFFSET is not the right thing to check because it makes
asssumptions about the layout of tss_struct. Nothing requires that the
I/O bitmap is placed right after x86_tss, which is the hardware mandated
tss structure. It pointlessly makes restrictions on the struct
tss_struct layout.
The proper thing to check is:
- Offset of x86_tss in tss_struct is 0
- Size of x86_tss == 0x68
Move it to the other build time TSS checks and make it do the right thing.
