* module: Don't report discarded init pages as kernel text.Rusty Russell2008-01-29
| | | | | | | | | | | | Current code could cause a bug in symbol_put_addr() if an arch used kmalloc module text: we might think the symbol belongs to the core kernel. The downside is that this might make backtraces through (discarded) init functions harder to read on some archs, but we already have that issue for modules and noone has complained.

| * [WATCHDOG] wdt: fix lockingAlan Cox2008-01-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The audit of _p usage shows various drivers assume inb_p is somehow atomic. Of course it isn't and the delay can be split from the I/O cycle causing a timing violation on chips that matter (eg this one) With the proposed use of udelay() for some _p delays this will cease to be a mostly theoretical bug (as the delay stall is unsplittable) and wants fixing. Lots of other drivers need fixing this way too. Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: Wim Van Sebroeck <wim@iguana.be> Signed-off-by: Andrew Morton <akpm@linux-foundation.org>

| * | sh: add spi header and r2d platform data V3Magnus Damm2008-01-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds the header file asm/spi.h and board specific code for the r2d board. The header file contains a structure that should be used to point out a single spi bus. The board specific code for r2d is updated with such a structure for the new spi_sh_sci driver. The structure contains a chip select callback plus information about the R9701 rtc chip which is attached to the spi bus.

| * | sh: update r7780rp interrupt codeMagnus Damm2008-01-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch updates the board specific irq code for r7780rp. The new code is very similar to the other highlander implementations, with the exception that the r7780rp handles pci interrupts using IRL. To simplify the pci code and use the same interrupt numbers as r7780mp and r7785rp we hook in to the cpu specific pci vectors. The pci interrupts and the push switch all work well with and without this patch. CF and AX88796 are not ok though and the source of the problem is unknown at this point. The AX88796 does for not detect it's proper mac address (IPL gets it right) and the kernel hangs on CF access. As a workaround this patch removes the CF and the AX88796 from the platform datain case of r7780rp. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now with the voyagergx cruft gone and the dreamcast using declared coherent memory for pci there are no users of the consistent alloc and free functions pointers in the machine vector.

This driver implements Sega's Packet Interface (SPI) - at least partially. It will also read disks in SEGA's propreitary GD format. Unlike previous drivers (which were never in mainline) this uses DMA and not PIO to read disks. It is a new driver, not a refactoring of old drivers.

The sm501fb driver should leave the pins FPEN and VBIASEN alone, and this patch instructs the driver to do so by not setting flags flags for these pins. This patch works best together with the patch posted to the linux-fbdev-devel list "sm501fb: control panel pin usage with platform data flags", but this patch can be merged independently.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch removes interrupt priority tables from the intc code.

The previous version matched the ARM, this version matches the PPC.

Additionally this reworks the use of the register banks, allowing for consolidation between the MMU and nommu implementations.
