* [MIPS] txx9: Make gpio_txx9 entirely spinlock-safeAtsushi Nemoto2008-07-151-4/+6
| | | | | | | | | TXx9 GPIO set/get routines are spinlock-safe. This patch make gpio_direction_{input,output} routines also spinlock-safe so that they can be used during early board setup. Signed-off-by: Atsushi Nemoto <anemo@mba.ocn.ne.jp> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

| | | | | | | | | | | | | | The following routines allocate_irqno() free_irqno() seem not to be used outside of the core kernel code, hence exporting these functions is pointless.

* [MIPS] fix sparse warning about setup_early_printk()Dmitri Vorobiev2008-07-152-5/+3
| | | | | | | | | | | | | | | | | | | This patch fixes the following sparse warning: <<<<<<<< arch/mips/kernel/early_printk.c:35:13: warning: symbol 'setup_early_printk' was not declared. Should it be static? <<<<<<<< The fix is to define a prototype of the setup_early_printk() function and to include the appropriate header into arch/mips/kernel/early_printk.c.

| | | | | | | | | | | | | | | | | | The txx9_tmr_init() will not clear a timer counter register in a certain case. The counter register is cleared on 1->0 transition of TCE bit if CRE=1.

* | remove div_long_long_remRoman Zippel2008-05-012-4/+6
|/ | | | | | | | | | | | | | | | | | | | | | x86 is the only arch right now, which provides an optimized for div_long_long_rem and it has the downside that one has to be very careful that the divide doesn't overflow. The API is a little akward, as the arguments for the unsigned divide are signed. The signed version also doesn't handle a negative divisor and produces worse code on 64bit archs. There is little incentive to keep this API alive, so this converts the few users to the new API.
