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.

Eliminate the sharing of IRQ names among the differenct Alchemy variants. IRQ numbers need no longer be hidden behind a CONFIG_SOC_AU1XXX symbol: step 1 in my quest to make the Alchemy code less reliant on a hardcoded subtype. This patch also renames the GPIO irq number constants. It's really an interrupt line, NOT a GPIO number! Code which relied on certain irq numbers to have the same name across all supported cpu subtypes is changed to determine current cpu subtype at runtime; in some places this isn't possible so a "compat" symbol is used. Run-tested on DB1200. Signed-off-by: NManuel Lauss <manuel.lauss@gmail.com> Signed-off-by: NRalf Baechle <ralf@linux-mips.org>

(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.

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.

Work around the CPU clock miscalculation on Au1000DA/HA/HB due the sys_cpupll register being write-only, i.e. actually do what the comment before cal_r4off() function advertised for years but the code failed at. This is achieved by just giving user a chance to define the clock explicitly in the board config. via CONFIG_SOC_AU1000_FREQUENCY option, defaulting to 396 MHz if the option is not given... The patch is based on the AMD's big unpublished patch, the issue seems to be an undocumented errata (or feature :-)...

Since we already moved to GENERIC_TIME, we should implement alternatives of old do_gettimeoffset routines to get sub-jiffies resolution from gettimeofday(). This patch includes: * MIPS clocksource support (based on works by Manish Lachwani). * remove unused gettimeoffset routines and related codes. * remove unised 64bit do_div64_32(). * simplify mips_hpt_init. (no argument needed, __init tag) * simplify c0_hpt_timer_init. (no need to write to c0_count) * remove some hpt_init routines. * mips_hpt_mask variable to specify bitmask of hpt value. * convert jmr3927_do_gettimeoffset to jmr3927_hpt_read. * convert ip27_do_gettimeoffset to ip27_hpt_read. * convert bcm1480_do_gettimeoffset to bcm1480_hpt_read. * simplify sb1250 hpt functions.

Pass ticks to do_timer() and update_times(), and adjust x86_64 and s390 timer interrupt handler with this change. Currently update_times() calculates ticks by "jiffies - wall_jiffies", but callers of do_timer() should know how many ticks to update. Passing ticks get rid of this redundant calculation. Also there are another redundancy pointed out by Martin Schwidefsky. This cleanup make a barrier added by 5aee405c needless. So this patch removes it. As a bonus, this cleanup make wall_jiffies can be removed easily, since now wall_jiffies is always synced with jiffies. (This patch does not really remove wall_jiffies. It would be another cleanup patch) Signed-off-by: NAtsushi Nemoto <anemo@mba.ocn.ne.jp> Cc: Martin Schwidefsky <schwidefsky@de.ibm.com> Cc: "Eric W.
