Build Update for openssl/openssl
-------------------------------------

Build: #5654
Status: Errored

Duration: 6 hours, 39 minutes, and 57 seconds
Commit: 9c8bca1 (OpenSSL_1_0_2-stable)
Author: Andy Polyakov
Message: bn/asm/x86[_64]-mont*.pl: implement slightly alternative page-walking.

Original strategy for page-walking was adjust stack pointer and then
touch pages in order. This kind of asks for double-fault, because
if touch fails, then signal will be delivered to frame above adjusted
stack pointer. But touching pages prior adjusting stack pointer would
upset valgrind. As compromise let's adjust stack pointer in pages,
touching top of the stack. This still asks for double-fault, but at
least prevents corruption of neighbour stack if allocation is to
overstep the guard page.

Also omit predict-non-taken hints as they reportedly trigger illegal
instructions in some VM setups.
