Being exported, AT_CLKTCK is returned by sysconf(_SC_CLK_TCK), glibc falls back to the hard-coded CLK_TCK value when aux entry is not present. Glibc versions prior to 2.2.1 always use hard-coded CLK_TCK value. For older applications/libc's which depends on hard-coded CLK_TCK value user should set compat.linux.osrelease less than 2.4.0. linux_times() shall use the value that is exported to user space.

Most of the code is modelled after what Linux does. This is because robust futexes are mostly userspace thing which we cannot alter. Two syscalls maintain pointer to userspace list and when process exits a routine walks this list waking up processes sleeping on futexes from that list. r183871: Make robust futexes work on linux32/amd64. Use PTRIN to read user-mode pointers. Change types used in the structures definitions to properly-sized architecture-specific types. r185002: In the robust futexes list head, futex_offset shall be signed, and glibc actually supplies negative offsets. Change l_ulong to l_long.

It never should have been committed in the first place, let alone migrated to linux emulation. r189362: Add AT_PLATFORM, AT_HWCAP and AT_CLKTCK auxiliary vector entries which are used by glibc. This silents the message "2.4+ kernel w/o ELF notes?" from some programs at start, among them are top and pkill. Do the assignment of the vector entries in elf_linux_fixup() as it is done in glibc. Fix some minor style issues.

Check that only MREMAP_FIXED and MREMAP_MAYMOVE flags are specified. Check for the page alignment of the addr argument. 2007-08-28T12:26:35Z Konstantin Belousov kib@FreeBSD.org 2007-08-28T12:26:35Z urn:sha1:b6e645c90f37e74056544503883f1cf02d290116 with Linux 2.6 emulation. This shall be reimplemented once FreeBSD gets native scheduler affinity syscalls.

Eliminate caller-side jail exception checking (also now-unused); jail privilege exception code now goes solely in kern_jail.c. We can't yet eliminate suser() due to some cases in the KAME code where a privilege check is performed and then used in many different deferred paths. Do, however, move those prototypes to priv.h.
