2008-04-28[MIPS] unexport null_perf_irq() and make it staticDmitri Vorobiev
This patch unexports the null_perf_irq() symbol, and simultaneously makes this function static. Signed-off-by: Dmitri Vorobiev <dmitri.vorobiev@gmail.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2008-04-28[MIPS] unexport rtc_mips_set_time()Dmitri Vorobiev
No users for the rtc_mips_set_time() routine exist outside of the core kernel code. Therefore, EXPORT_SYMBOL(rtc_mips_set_time) is useless, and this patch removes it. Signed-off-by: Dmitri Vorobiev <dmitri.vorobiev@gmail.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

2008-04-28[MIPS] unexport copy_to_user_page()Dmitri Vorobiev

Since the commit 91a2fcc88634663e9e13dcdfad0e4a860e64aeee ([MIPS] Consolidate all variants of MIPS cp0 timer interrupt handlers) removed the Alchemy specific timer handler, 'r4k_offset' and 'r4k_cur' variables became practically useless, so get rid of them at last, renaming cal_r4off() function into calc_clock() and making it return CPU frequency.

Defer the unmasking of the count/compare interrupt (IRQ5) till the clockevent driver initialization: - only enable the cascaded IRQs 0 thru 4 in arch_init_irq(); kill the ALLINTS macro -- this change is blessed by AMD as I saw it in their own patch; :-) - do not force IRQ5 enabled in plat_time_init() if PM is enabled and there's no 32 KHz crystal.

2008-04-28[MIPS] Reimplement clear_page/copy_pageThiemo Seufer
Fold the SB-1 specific implementation of clear_page/copy_page in the generic version, and rewrite that one in tlbex style. The immediate benefits: - It converts the compile-time workaround for SB-1 pass 1 prefetches to a more efficient run-time check. - It allows adjustment of loop unfolling, which helps to reduce the number of redundant cdex cache ops. - It fixes some esoteric cornercases (the cache line length calculations can go wrong, and support for 64k pages without prefetch instructions will overflow the addiu immediate). - Somewhat better guesses of "good" prefetch values.

The header files for the Pb1200/DBAu1200 boards have wrong definition for the IDE interface's decoded range length -- it should be 512 bytes according to what the IDE driver does. In addition, the IDE platform device claims 1 byte too many for its memory resource -- fix the platform code and the IDE driver in accordance.

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...
