2017-08-24x86/lguest: Remove lguest supportJuergen Gross1-192/+0
Lguest seems to be rather unused these days. It has seen only patches ensuring it still builds the last two years and its official state is "Odd Fixes". Remove it in order to be able to clean up the paravirt code.

2015-03-24lguest: suppress interrupts for single insn, not range.Rusty Russell1-9/+6
The last patch reduced our interrupt-suppression region to one address, so simplify the code somewhat. Also, remove the obsolete undefined instruction ranges and the comment which refers to lguest_guest.S instead of head_32.S. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

2015-03-20lguest: fix pending interrupt test.Rusty Russell1-1/+1
Denys says: TEST with zero will always set ZF. Thus, "jnz send_interrupts" never jumps. We get interrupts regularly enough that this didn't cause immediate problems. Reported-by: Denys Vlasenko <vda.linux@googlemail.com> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
