* power management: implement pm_ops.valid for everybodyJohannes Berg2007-04-30
| | | | | | | | | | | | | | | | | | | | | | 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.

* rework pm_ops pm_disk_mode, kill misuseJohannes Berg2007-04-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

The requested reg resource was checked to see if it exceeded the size of the reg property, but not to see if it exceeded the size of the buffer.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 32-bit powerpc systems define a macro, PHYS_FMT, giving a printf format string fragment for displaying physical addresses, since most 32-bit powerpc platforms use 32-bit physical addresses but a few use 64-bit physical addresses. This macro is used in exactly one place, a rare error message, where we can solve the problem more simply by just unconditionally casting the address up to 64-bit quantity before formatting it. This patch does so, meaning that as we bring MMU definitions from asm-ppc over to asm-powerpc, cleaning them up in the process, we don't need to implement this ugly macro (which additionally has a very bad name for something global).

| * | [POWERPC] Cleanup and fix breakage in tlbflush.hDavid Gibson2007-04-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | BenH's commit a741e67969577163a4cfc78d7fd2753219087ef1 in powerpc.git, although (AFAICT) only intended to affect ppc64, also has side-effects which break 44x. I think 40x, 8xx and Freescale Book E are also affected, though I haven't tested them. The problem lies in unconditionally removing flush_tlb_pending() from the versions of flush_tlb_mm(), flush_tlb_range() and flush_tlb_kernel_range() used on ppc64 - which are also used the embedded platforms mentioned above. The patch below cleans up the convoluted #ifdef logic in tlbflush.h, in the process restoring the necessary flushes for the software TLB platforms. There are three sets of definitions for the flushing hooks: the software TLB versions (revised to avoid using names which appear to related to TLB batching), the 32-bit hash based versions (external functions) amd the 64-bit hash based versions (which implement batching). It also moves the declaration of update_mmu_cache() to always be in tlbflush.h (previously it was in tlbflush.h except for PPC64, where it was in pgtable.h). Booted on Ebony (440GP) and compiled for 64-bit and 32-bit multiplatform.

| * | [POWERPC] Save trap number in bad_stackOlof Johansson2007-04-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | Save the trap number in the case of getting a bad stack in an exception handler. It is sometimes useful to know what exception it was that caused this to happen. Without this, no trap number is reported.

| | | | | | | | | | | | | | | | | | | | | | | | | | | Rename MPIC_BROKEN_U3 to something a little more descriptive. Its effect is to enable support for HT irqs behind the PCI-X/HT bridge on U3/U4 (aka. CPC9x5) parts.
