selftests/x86/mpx: Fix incorrect bounds with old _sigfault
commit 961888b1d76d84efc66a8f5604b06ac12ac2f978 upstream.
For distributions with old userspace header files, the _sigfault
structure is different. mpx-mini-test fails with the following
error:
[root@Purley]# mpx-mini-test_64 tabletest
XSAVE is supported by HW & OS
XSAVE processor supported state mask: 0x2ff
XSAVE OS supported state mask: 0x2ff
BNDREGS: size: 64 user: 1 supervisor: 0 aligned: 0
BNDCSR: size: 64 user: 1 supervisor: 0 aligned: 0
starting mpx bounds table test
ERROR: siginfo bounds do not match shadow bounds for register 0
Fix it by using the correct offset of _lower/_upper in _sigfault.
RHEL needs this patch to work.
