* work around linux bug in mprotectRich Felker2011-06-291-1/+5
| | | | | | | | | | | per POSIX: The mprotect() function shall change the access protections to be that specified by prot for those whole pages containing any part of the address space of the process starting at address addr and continuing for len bytes. on the other hand, linux mprotect fails with EINVAL if the base address and/or length is not page-aligned, so we have to align them before making the syscall.
* fix missing include in posix_madvise.c (compile error)Rich Felker2011-04-201-0/+1

* cleaning up syscalls in preparation for x86_64 portRich Felker2011-02-131-0/+4
| | | | | | | | | - hide all the legacy xxxxxx32 name cruft in syscall.h so the actual source files can be clean and uniform across all archs. - cleanup llseek/lseek and mmap2/mmap handling for 32/64 bit systems - alternate implementation for nice if the target lacks nice syscall
* initial check-in, version 0.5.0 v0.5.0Rich Felker2011-02-1211-0/+107
