x86/asm/entry/32, selftests: Add a selftest for kernel entries from VM86 mode
Test a couple of special cases in 32-bit kernels for entries
from vm86 mode. This will OOPS both old kernels due to a bug
and and 4.1-rc5 due to a regression I introduced, and it should
make sure that the SYSENTER-from-vm86-mode hack in the kernel
keeps working.
