* Remove unnecessary casts of 'a' to char * since 'a' is already char *.millert2017-01-041-10/+10
| | | | | This is a remnant from the original 4.4BSD code that had 'a' as void * in the function args. No binary change. OK bluhm@

* remove some old option letters and also make P non-settable. It hasotto2016-10-311-24/+6
| | | | | been the default for ages, and I see no valid reason to be able to disable it. ok natano@
* Pages in the malloc cache are either reused quickly or unmappedotto2016-10-281-14/+1
| | | | | | quickly. In both cases it does not make sense to set hints on them. So remove that option, which is just a remainder of old times when malloc used to hold on to pages. ok stefan@
