ARM: Make the sched_clock framework mandatory

2012-02-03T11:34:27+00:00

All sched_clock() providers have been converted to the sched_clock
framework, which also provides a jiffy based implementation for
the platforms that do not provide a counter.

It is now possible to make the sched_clock framework mandatory,
effectively preventing new platforms to add new sched_clock()
functions, which would be detrimental to the single zImage work.

ARM: remove mc146818rtc.h from time.c

2012-01-26T02:37:44+00:00

mc146818rtc.h is not needed in time.c, so remove it.

arm: convert core files from module.h to export.h

2011-10-31T23:30:49+00:00

Many of the core ARM kernel files are not modules, but just
including module.h for exporting symbols.  Now these files can
use the lighter footprint export.h for this role.

There are probably lots more, but ARM files of mach-* and plat-*
don't get coverage via a simple yesconfig build.  They will have
to be cleaned up and tested via using their respective configs.

ARM: export rtc_lock for nvram driver

2011-10-01T19:08:26+00:00

The rtc_lock is used by both the nvram and rtc drivers, so
we need to export it if at least one of the two is built,
not just for the rtc driver.

ARM: Use struct syscore_ops instead of sysdevs for PM in common code

2011-04-24T17:16:08+00:00

Convert some ARM architecture's common code to using
struct syscore_ops objects for power management instead of sysdev
classes and sysdevs.

This simplifies the code and reduces the kernel's memory footprint.
It also is necessary for removing sysdevs from the kernel entirely in
the future.

arm: Switch from do_timer() to xtime_update()

2011-01-31T13:55:43+00:00

xtime_update takes the xtime_lock itself.

ARM: sched_clock: allow init_sched_clock() to be called early

2011-01-11T16:23:04+00:00

sched_clock is supposed to be initialized early - in the recently added
init_early platform hook.  However, in doing so we end up calling
mod_timer() before the timer lists are initialized, resulting in an
oops.

Split the initialization in two - the part which the platform calls
early which starts things off.  The addition of the timer can be
delayed until after we have more of the kernel initialized - when the
normal time sources are initialized.

ARM: simplify early machine init hooks

2010-12-24T09:49:51+00:00

Rather than storing each machine init hook separately, store a
pointer to the machine description record and dereference this
instead.  This pointer is only available while the init sections
are present, which is not a problem as we only use it from init
code.

ARM: convert arm to arch_gettimeoffset()

2010-03-24T08:08:58+00:00

Convert arm to use GENERIC_TIME via the arch_getoffset() infrastructure,
reducing the amount of arch specific code we need to maintain.

The arm architecture is the last arch that need to be converted.
