um/time: Migrate to new 'set-state' interface

2015-08-10T09:41:06+00:00

Migrate um driver to the new 'set-state' interface provided by
clockevents core, the earlier 'set-mode' interface is marked obsolete
now.

This also enables us to implement callbacks for new states of clockevent
devices, for example: ONESHOT_STOPPED.

um: pass siginfo to guest process

2012-08-01T22:49:17+00:00

UML guest processes now get correct siginfo_t for SIGTRAP, SIGFPE,
SIGILL and SIGBUS. Specifically, si_addr and si_code are now correct
where previously they were si_addr = NULL and si_code = 128.

um: irq: Remove IRQF_DISABLED

2012-03-24T23:29:52+00:00

Since commit [e58aa3d2: genirq: Run irq handlers with interrupts disabled],
We run all interrupt handlers with interrupts disabled
and we even check and yell when an interrupt handler
returns with interrupts enabled (see commit [b738a50a:
genirq: Warn when handler enables interrupts]).

So now this flag is a NOOP and can be removed.

clocksource: um: Convert to clocksource_register_hz/khz

2011-11-22T03:01:03+00:00

This converts the um clocksource to use clocksource_register_hz/khz

This is untested, so any assistance in testing would be appreciated!

um: Fix read_persistent_clock fallout

2010-08-03T18:36:07+00:00

commit 9f31f57(um: Convert to use read_persistent_clock) moved the
code, but not the variable.

um: Convert to use read_persistent_clock

2010-07-27T10:40:55+00:00

This patch converts the um arch to use read_persistent_clock().
This allows it to avoid accessing xtime and wall_to_monotonic
directly.

clocksource: pass clocksource to read() callback

2009-04-21T20:41:47+00:00

Pass clocksource pointer to the read() callback for clocksources.  This
allows us to share the callback between multiple instances.

cpumask: convert struct clock_event_device to cpumask pointers.

2008-12-13T10:50:26+00:00

Impact: change calling convention of existing clock_event APIs

struct clock_event_timer's cpumask field gets changed to take pointer,
as does the ->broadcast function.

Another single-patch change.  For safety, we BUG_ON() in
clockevents_register_device() if it's not set.

UML: make several more things static

2008-07-24T17:47:24+00:00

- Make some variables and functions static, since they don't need to be
  global.

- Remove an unused function - arch/um/kernel/time.c::sched_clock().

- Clean the style a bit as complained by checkpatch.pl.
