sparc: drop use of extern for prototypes in arch/sparc/include/asm

2014-05-19T02:01:29+00:00

Drop extern for all prototypes and adjust alignment of parameters
as required after the removal.
In a few rare cases adjust linelength to conform to maximum 80 chars,
and likewise in a few rare cases adjust alignment of parameters
to static functions.

sparc32: fix sparse warnings in time_32.c

2014-05-19T02:01:27+00:00

Fix following warnings:
time_32.c:63:1: warning: symbol 'rtc_lock' was not declared. Should it be static?
time_32.c:357:13: warning: symbol 'time_init' was not declared. Should it be static?
time_32.c:148:16: warning: dereference of noderef expression

Add extern definition of rtc_lock in mc146818rtc.h.
time_init() is called from init/main.c - add prototype to kernel.h.
Use proper u32 __iomem * for master_l10_counter.
Fix all users.

sparc32: fix sparse warnings in sun4m_irq.c and sun4d_irq.c

2014-04-29T05:12:25+00:00

Fix following warnings:

sun4m_irq.c:308:6: warning: symbol 'sun4m_nmi' was not declared. Should it be static?
sun4m_irq.c:396:28: warning: incorrect type in assignment (different address spaces)
sun4m_irq.c:396:28:    expected unsigned int volatile *extern [addressable] [toplevel] master_l10_counter
sun4d_irq.c:469:28: warning: incorrect type in assignment (different address spaces)
sun4d_irq.c:469:28:    expected unsigned int volatile *extern [addressable] [toplevel] master_l10_counter

master_l10_counter is a pointer to __iomem - add annotations.

sparc32: generic clockevent support

2012-04-15T17:28:50+00:00

The kernel uses l14 timers as clockevents. l10 timer is used
as clocksource if platform master_l10_counter isn't constantly
zero. The clocksource is continuous, so it's possible to use
high resolution timers. l10 timer is also used as clockevent
on UP configurations.

This realization is for sun4m, sun4d, sun4c, microsparc-IIep
and LEON platforms. The appropriate LEON changes was made by
Konrad Eisele.

In case of sun4m's oneshot mode, profile irq is zeroed in
smp4m_percpu_timer_interrupt(). It is maybe
needless (double, triple etc overflow does nothing).

sun4d is able to have oneshot mode too, but I haven't
any way to test it. So code of its percpu timer handler
is made as much equal to the current code as possible.

The patch is tested on sun4m box in SMP mode by me,
and tested by Konrad on leon in up mode (leon smp
is broken atm - due to other reasons).
