2018-01-31iotests: Make 200 run on tmpfsMax Reitz
200 currently fails on tmpfs because it sets cache=none. However, without that (and aio=native), the test still works now and it fails before Jeff's series (on fc7dbc119e0852a70dc9fa68bb41a318e49e4cd6). So we can probably remove the aio=native safely, and replace cache=none by cache=$CACHEMODE.

2018-01-31block/ssh: fix possible segmentation fault when .desc is not null-terminatedMurilo Opsfelder Araujo
This patch prevents a possible segmentation fault when .desc members are checked against NULL. The ssh_runtime_opts was added by commit 8a6a80896d6af03b8ee0c17cdf37219eca2588a7 ("block/ssh: Use QemuOpts for runtime options"). This fix was inspired by http://lists.nongnu.org/archive/html/qemu-devel/2018-01/msg00883.html.

2018-01-31target/hppa: Only use EXCP_DTLB_MISSRichard Henderson
Unknown why this works, but if we return EXCP_ITLB_MISS we will triple-fault the first userland instruction fetch. Is it something to do with having a combined I/DTLB? Signed-off-by: Richard Henderson <richard.henderson@linaro.org>

2018-01-30ipmi: disable IRQ and ATN on an external disconnectCorey Minyard

2018-01-30ipmi: Fix macro issuesCorey Minyard
Macro parameters should almost always have () around them when used. llvm reported an error on this. Remove redundant parenthesis and put parenthesis around the entire macros with assignments in case they are used in an expression. The macros were doing ((v) & 1) for a binary input, but that only works if v == 0 or if v & 1. Changed to !!(v) so they work for all values. Remove some unused macros. Reported in https://bugs.launchpad.net/bugs/1651167 An audit of these changes found no semantic changes; this is just cleanups for proper style and to avoid a compiler warning.

2018-01-30ipmi: Don't set the timestamp on add events that don't have itCorey Minyard
According to the spec, from section "32.3 OEM SEL Record - Type E0h-FFh", event types from 0x0e to 0xff do not have a timestamp. So don't set it when adding those types. This required putting the timestamp in a temporary buffer, since it's still required to set the last addition time.
