2008-01-24Driver core: change sysdev classes to use dynamic kobject namesKay Sievers2-2/+2
All kobjects require a dynamically allocated name now. We no longer need to keep track if the name is statically assigned, we can just unconditionally free() all kobject names on cleanup. Signed-off-by: Kay Sievers <kay.sievers@vrfy.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2008-01-24Kobject: convert arch/* from kobject_unregister() to kobject_put()Greg Kroah-Hartman1-1/+1
There is no need for kobject_unregister() anymore, thanks to Kay's kobject cleanup changes, so replace all instances of it with kobject_put(). Cc: Kay Sievers <kay.sievers@vrfy.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2008-01-24Kobject: change arch/sh/kernel/cpu/sh4/sq.c to use kobject_init_and_addGreg Kroah-Hartman1-5/+6
Stop using kobject_register, as this way we can control the sending of the uevent properly, after everything is properly initialized. Cc: Kay Sievers <kay.sievers@vrfy.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2007-11-30sh: Support PCI IO access of SH7780 base boards.Nobuhiro Iwamatsu2-4/+4
The IO access of PCI is not supported in R7780RP and the MS7780SE board now. The support of the IO access mode of e100 and a lot of IDE chips becomes possible by fixing the code. Signed-off-by: Nobuhiro Iwamatsu <iwamatsu@nigauri.org> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-11-30sh: Fix PCI IO space base address of SH7780.Nobuhiro Iwamatsu1-1/+1
PCI IO space base address of SH7780 was wrong. Change from 0xFE400000 to 0xFE200000. Signed-off-by: Nobuhiro Iwamatsu <iwamatsu@nigauri.org> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-11-23sh: include ax88796 in the defconfig for r7785rpMagnus Damm1-5/+5

2007-11-23sh: include ax88796 in the defconfig for r7780mpMagnus Damm1-198/+89

2007-11-23sh: fix R2D-1 CF supportMagnus Damm1-0/+2
This patch fixes CF support for R2D-1 boards. Both R2D-1 and R2D-PLUS are equipped with CF IRQs, but the R2D-1 FPGA version seem to deliver IRQ spikes with certain CF cards during libata probing. This patch enables polling for R2D-1 as a workaround for this broken FGPA logic. R2D-1 CF support was recently introduced by commit: 43f4b8c7578b928892b6f01d374346ae14e5eb70.

2007-11-19sh: lockless UTLB miss fast-path.Paul Mundt1-18/+7
With the refactored update_mmu_cache() introduced in older kernels, there's no longer any need to take the page_table_lock in this path, so simply drop it completely. Without this, performance degradation is seen on SMP on heavily threaded workloads that don't use the split ptlock, and ultimately we have no reason to contend for the lock in the first place. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-11-19sh: Kill off UTLB flush in fast-path.Paul Mundt1-8/+0
The __do_page_fault() fast-path contains a UTLB flush in order to force an ITLB reload, this isn't needed in practice as the ITLB is auto-reloaded from the UTLB anyways, which is already displaced by the manual 'ldtlb' in the update_mmu_cache() path. This provides a measurable speed up in the TLB miss fast-path. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2007-11-08sh: Kill off broken snapgear ds1302 code.Paul Mundt3-326/+2
This will force the snapgear boards to use the on-chip SH RTC instead, until the rtc-ds1302 driver is merged. The current code is broken and hasn't built in some time, so just kill it off and get the board working again. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
