BugLink: https://launchpad.net/bugs/1818552 The a.out core dump handler is broken and will be removed in 5.1 with upstream commit 08300f44 ("a.out: remove core dumping support"). Additionally, all a.out support will be deprecated in 5.1 with upstream commit eac61655 ("x86: Deprecate a.out support") and completely removed in a future release. Disable it in Ubuntu since it is risky to leave enabled and there are likely no users that depend on it. Signed-off-by:

BugLink: https://bugs.launchpad.net/bugs/1703742 The current configuration is set to always use transparent hugepages by default. There exists plenty of anecdotal evidence that this is less than perfect a choice and in some scenarios it leads to some performance issues. My own investigations with stress-ng stream and malloc tests show that the current default impacts performance. I ran various test scenarios on different MADVISE configurations, each result below is based on the average of 5 runs on an i7-3770 CPU @ 3.4GHz with 8GB memory, 8MB L3 cache, 256K L2 cache, 32K/32K L1 cache. All the above results are from an average of 5 rounds of tests. malloc allocation stressor: malloc always madvise size (MB) ops/sec ops/sec 32 1254.43 2422.49 64 2100.36 4300.28 128 3768.57 7215.38 256 7940.73 14893.85 512 17618.62 26861.29 1024 32777.17 48029.37 Clearly madvise is more performent. stream bandwidth/compute stressor: stream always madvise NOHUGEPAGE size (MB) MB/sec MB/sec 1 17713.54 18439.69 2 12460.34 13015.46 4 12195.81 12694.51 8 12085.11 12674.26 16 12054.09 12649.00 32 12082.42 12409.65 64 12262.88 12084.85 128 12235.25 11788.49 256 11808.69 11283.69 512 11970.01 12434.82 For small allocations, always is less performant. Large allocations can enable the more performant transparent huge pages with madvise(2) if we disable always as default. Other stress-ng memory allocation/writing/freeing and madvise operations showed little significant differences. I have also experimented with boot testing Ubuntu with kernels configured with different MADVISE configs and found there is little noticeable difference in performance, so I believe that there is little scope for any kitten killer performance regressions with this change. This change will by default not use transparent huge pages unless madvise(2) is used to instruct the kernel to do so on a memory mapping. According to the madvise(2) manual, this only takes effect on private anonymous mappings with MADV_HUGEPAGE. Signed-off-by:
