Merge branch 'sp/mmap'
* sp/mmap: (27 commits) Spell default packedgitlimit slightly differently Increase packedGit{Limit,WindowSize} on 64 bit systems. Update packedGit config option documentation. mmap: set FD_CLOEXEC for file descriptors we keep open for mmap() pack-objects: fix use of use_pack(). Fix random segfaults in pack-objects. Cleanup read_cache_from error handling. Replace mmap with xmmap, better handling MAP_FAILED. Release pack windows before reporting out of memory. Default core.packdGitWindowSize to 1 MiB if NO_MMAP. Test suite for sliding window mmap implementation. Create pack_report() as a debugging aid. Support unmapping windows on 'temporary' packfiles. Improve error message when packfile mmap fails. Ensure core.packedGitWindowSize cannot be less than 2 pages. Load core configuration in git-verify-pack. Fully activate the sliding window pack access. Unmap individual windows rather than entire files. Document why header parsing won't exceed a window. Loop over pack_windows when inflating/accessing data. ... Conflicts: cache.h pack-check.c
