The res member of kclock is only used by mmtimer.c, but even there it contains redundant information. Remove the field and fixup mmtimer. Signed-off-by:

Richard said: "I would think that we can require k_clocks to provide the read function. This could be checked and enforced in register_posix_clock()." Add checks for clock_getres and clock_get in the register function. Suggested-by:

CLOCK_THREAD_CPUTIME_ID implements stub functions for nanosleep and nanosleep_restart, which return -EINVAL. That return value is wrong. The correct return value is -ENOTSUP. Remove the stubs and let the new dispatch code return the correct error code. Signed-off-by:

New function to find the kclock for a given clockid. Returns a pointer to clock_posix_cpu if clockid < 0. If clockid >= MAXCLOCK or if the clock_getres pointer is not set it returns NULL. For valid clocks it returns a pointer to the matching posix_clock. Signed-off-by:

The CLOCK_DISPATCH() macro is a horrible magic. We call common functions if a function pointer is not set. That's just backwards. To support dynamic file decriptor based clocks we need to cleanup that dispatch logic. Create a k_clock struct clock_posix_cpu which has all the posix-cpu-timer functions filled in. After the cleanup the functions can be made static. Signed-off-by:

Both settimeofday() and clock_settime() promise with a 'const' attribute not to alter the arguments passed in. This patch adds the missing 'const' attribute into the various kernel functions implementing these calls. Signed-off-by:

All callers of do_timer() are converted to xtime_update(). The only users of xtime_lock are in kernel/time/. Make both local to kernel/time/ and remove them from the global header files. [ tglx: Reuse tick-internal.h instead of creating another local header file. Massaged changelog ] Signed-off-by:
