Jason Evans 245ae6036c Support --with-lg-page values larger than actual page size. ... During over-allocation in preparation for creating aligned mappings, allocate one more page than necessary if PAGE is the actual page size, so that trimming still succeeds even if the system returns a mapping that has less than PAGE alignment. This allows compiling with e.g. 64 KiB "pages" on systems that actually use 4 KiB pages. Note that for e.g. --with-lg-page=21, it is also necessary to increase the chunk size (e.g. --with-malloc-conf=lg_chunk:22) so that there are at least two "pages" per chunk. In practice this isn't a particularly compelling configuration because so much (unusable) virtual memory is dedicated to chunk headers.		2016-04-11 02:35:00 -07:00
