Each board sets the total number of IRQs that it's interested in via the machvec. Previously we cared about the off vs on-chip IRQ range, but any code relying on that is long dead. Set NR_IRQS to something sensible given the vector range, and allow boards to cap it if they really care. Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

Wire up GENERIC_BUG for SH. This moves off of the special bug frame and on to the generic struct bug_entry. Roughly the same semantics are retained, and we can kill off some of the verbose BUG() reporting code. Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

SH7780 has a speculative execution mode where it can speculatively perform an instruction fetch for subroutine returns, this allows it to be enabled. There are some various pitfalls associated with this mode, so it's left as depending on CONFIG_EXPERIMENTAL and not enabled by default. Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

The kgdb thread support is woefully out of date (it predates the pidhash), and needs a complete rewrite before it's useful again. Just rip it out entirely. Updating the unified kgdb stub is a more worthwhile endeavour for anyone that happens to be interested in this, at present it's just limping along. Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

Let's allow page-alignment in general for per-cpu data (wanted by Xen, and Ingo suggested KVM as well). Because larger alignments can use more room, we increase the max per-cpu memory to 64k rather than 32k: it's getting a little tight.

Almost all users of pm_ops only support mem sleep, don't check in .valid and don't reject any others in .prepare so users can be confused if they check /sys/power/state, especially when new states are added (these would then result in s-t-r although they're supposed to be something different). This patch implements a generic pm_valid_only_mem function that is then exported for users and puts it to use in almost all existing pm_ops.

This patch series cleans up some misconceptions about pm_ops. Some users of the pm_ops structure attempt to use it to stop the user from entering suspend to disk, this, however, is not possible since the user can always use "shutdown" in /sys/power/disk and then the pm_ops are never invoked. Also, platforms that don't support suspend to disk simply should not allow configuring SOFTWARE_SUSPEND (read the help text on it, it only selects suspend to disk and nothing else, all the other stuff depends on PM). The pm_ops structure is actually intended to provide a way to enter platform-defined sleep states (currently supported states are "standby" and "mem" (suspend to ram)) and additionally (if SOFTWARE_SUSPEND is configured) allows a platform to support a platform specific way to enter low-power mode once everything has been saved to disk. This is currently only used by ACPI (S4). This patch: The pm_ops.pm_disk_mode is used in totally bogus ways since nobody really seems to understand what it actually does. This patch clarifies the pm_disk_mode description. It also removes all the arm and sh users that think they can veto suspend to disk via pm_ops; not so since the user can always do echo shutdown > /sys/power/disk, they need to find a better way involving Kconfig or such. ACPI is the only user left with a non-zero pm_disk_mode. The patch also sets the default mode to shutdown again, but when a new pm_ops is registered its pm_disk_mode is selected as default, that way the default stays for ACPI where it is apparently required.

When a SH7751R system includes a card that has wide range space like a graphics card, the pci-pci bridge controller can't set the correct address range. For example, when *lower_limit is 0xfd000000 and bar_size is 0x4000000, in the following code at arch/sh/drivers/pci/pci-auto.c, 0x0 is set in bar_value. pciauto_setup_bars() { ... bar_value = ((*lower_limit - 1) & ~(bar_size - 1)) + bar_size; ... *lower_limit = bar_value + bar_size; } As a result, 0x4000000 is set in *lower_limit, but this value is wrong. The following patch avoids this problem by checking the range of the value and refusing to update the BAR if the calculated value ends up being bogus.

When I run a preemptive kernel-2.6.20 for SH7780, a created kthread(pdflush) can not exit by do_exit() in kernel_thread_helper. I think that the created kthread should have a room for 'struct pt_regs' space on the stack top, because __switch_to() will refer to the space as follows using 'regs = task_pt_regs(prev)' and next condition may be true.

This patch does the following: - remove the make_ipr_irq stuff from dma-sh.c and replace it with a simple channel<->irq mapping table. - add DMTEx_IRQ constants for sh4 cpus - fix sh7751 DMAE irq number The SH7780 uses the same IRQs for DMA as other SH4 types, so I put the constants on top of the dma.h file.
