2009-09-24cpumask: remove dangerous CPU_MASK_ALL_PTR, &CPU_MASK_ALL.: mipsRusty Russell
(Thanks to Al Viro for reminding me of this, via Ingo) CPU_MASK_ALL is the (deprecated) "all bits set" cpumask, defined as so: #define CPU_MASK_ALL (cpumask_t) { { ... } } Taking the address of such a temporary is questionable at best, unfortunately 321a8e9d (cpumask: add CPU_MASK_ALL_PTR macro) added CPU_MASK_ALL_PTR: #define CPU_MASK_ALL_PTR (&CPU_MASK_ALL) Which formalizes this practice. One day gcc could bite us over this usage (though we seem to have gotten away with it so far). So replace everywhere which used &CPU_MASK_ALL or CPU_MASK_ALL_PTR with the modern "cpu_all_mask" (a real struct cpumask *), and remove CPU_MASK_ALL_PTR altogether.

2009-09-17MIPS: Alchemy: get rid of allow_au1k_waitManuel Lauss
Eliminate the 'allow_au1k_wait' variable. MIPS kernel installs the Alchemy-specific wait code before timer initialization; if the C0 timer must be used for timekeeping the wait function is set to NULL which means no wait implementation is available. As a sideeffect, the 'wait instruction available' output in /proc/cpuinfo now correctly indicates whether 'wait' is usable. Run-tested on DB1200.

2009-02-27MIPS: Alchemy: In plat_time_init() t reaches -1, tested: 0Roel Kluin
With a postfix decrement t reaches -1 rather than 0, so the fall-back will not occur. Signed-off-by: Roel Kluin <roel.kluin@gmail.com> Cc: mano@roarinelk.homelinux.net Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

In Linus' current -git the cpumask member is now a pointer. Signed-off-by: Manuel Lauss <mano@roarinelk.homelinux.net> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2009-01-11MIPS: Alchemy: move calc_clock function.Manuel Lauss
Now that nothing in time.c depends on calc_clock, it can be moved to clocks.c where it belongs. While at it, give it a better non-generic name and call it as soon as possible in plat_mem_init.

2009-01-11MIPS: Alchemy: RTC counter clocksource / clockevent support.Manuel Lauss
Add support for the 32 kHz counter1 (RTC) as clocksource / clockevent device. As a nice side effect, this also enables use of the 'wait' instruction for runtime idle power savings. If the counters aren't enabled/working properly, fall back on the cp0 counter clock code. Signed-off-by: Manuel Lauss <mano@roarinelk.homelinux.net> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2009-01-11MIPS: Alchemy: remove cpu_table.Manuel Lauss
Remove the cpu_table: - move detection of whether c0_config[OD] is read-only and should be set to fix various chip errata to au1000 headers. - move detection of write-only sys_cpupll to au1000 headers. - remove the BCLK switching code: Activation of this features should be left to the boards using the chips since it also affects external devices tied to BCLK, and only the board designers know whether it is safe to enable.
