For anyone wants to contribute to 9legacy. Very big changes from Geoff: * Porting [regfree | https://collyer.net/magic/man2html/2/regexp] and make all programs to use it. There are a hundred instances of regfree in Geoff's tree right now, mostly in the compilers :) * [change ulong to uintptr | https://9legacy.org/9legacy/patch/uintptr.diff]. 9legacy programs is currently restricted to 4gb of ram, and the 9k kernel seems to have a limitation of 2.4gb, lol! These patches should be backported from 9 to 9k (of 9legacy) * [9-proc-procflushseg | https://9legacy.org/9legacy/patch/9-proc-procflushseg.diff] Done: * [9-proc-rebalance | https://9legacy.org/9legacy/patch/9-proc-rebalance.diff] * [9-proc-pexit | https://9legacy.org/9legacy/patch/9-proc-pexit.diff] * [9-sysproc-close-on-exec | https://9legacy.org/9legacy/patch/9-sysproc-close-on-exec.diff] * [9-routewrite-cmdbuf | https://9legacy.org/9legacy/patch/9-routewrite-cmdbuf.diff] * [9-devtls-maxtlsdevs | https://9legacy.org/9legacy/patch/9-devtls-maxtlsdevs.diff] * [9-devtls-leak | https://9legacy.org/9legacy/patch/9-devtls-leak.diff] * [9-devtls-zero-length-records | https://9legacy.org/9legacy/patch/9-devtls-zero-length-records.diff]
