New Revision: 303699
URL: https://svnweb.freebsd.org/changeset/base/303699
Log:
mprotect(): Change prototype to comply to POSIX.
Our mprotect() function seems to take a "const void *" address to the
pages whose permissions need to be adjusted. POSIX uses "void *". Simply
stick to the POSIX one to prevent us from writing unportable code.
PR: 211423 (exp-run)
Tested by: antoine@ (Thanks!)
