timers: Remove stale struct tvec_base forward declaration

2018-04-17T15:18:04+00:00

struct tvec_base is a leftover of the original timer wheel implementation
and not longer used. Remove the forward declaration.

timers: Reinitialize per cpu bases on hotplug

2017-12-29T22:13:09+00:00

The timer wheel bases are not (re)initialized on CPU hotplug. That leaves
them with a potentially stale clk and next_expiry valuem, which can cause
trouble then the CPU is plugged.

Add a prepare callback which forwards the clock, sets next_expiry to far in
the future and reset the control flags to a known state.

Set base->must_forward_clk so the first timer which is queued will try to
forward the clock to current jiffies.

treewide: Remove TIMER_FUNC_TYPE and TIMER_DATA_TYPE casts

2017-11-22T00:35:54+00:00

With all callbacks converted, and the timer callback prototype
switched over, the TIMER_FUNC_TYPE cast is no longer needed,
so remove it. Conversion was done with the following scripts:

    perl -pi -e 's|\(TIMER_FUNC_TYPE\)||g' \
        $(git grep TIMER_FUNC_TYPE | cut -d: -f1 | sort -u)

    perl -pi -e 's|\(TIMER_DATA_TYPE\)||g' \
        $(git grep TIMER_DATA_TYPE | cut -d: -f1 | sort -u)

The now unused macros are also dropped from include/linux/timer.h.

timer: Remove redundant __setup_timer*() macros

2017-11-21T23:57:15+00:00

With __init_timer*() now matching __setup_timer*(), remove the redundant
internal interface, clean up the resulting definitions and add more
documentation.

timer: Pass function down to initialization routines

2017-11-21T23:57:14+00:00

In preparation for removing more macros, pass the function down to the
initialization routines instead of doing it in macros.

can be removed.

timer: Switch callback prototype to take struct timer_list * argument

2017-11-21T23:57:13+00:00

Since all callbacks have been converted, we can switch the core
prototype to "struct timer_list *" now too.

timer: Pass timer_list pointer to callbacks unconditionally

2017-11-21T23:57:12+00:00

Now that all timer callbacks are already taking their struct timer_list
pointer as the callback argument, just do this unconditionally and remove
the .data field.
