This should fix a suspend/resume issues that appear with OHCI on some PPC hardware. The PCI layer should doesn't have the hooks needed for such ASIC-specific hooks (in this case, software clock gating), so this moves the code to do that into hcd-pci.c ... where it can be done after the relevant PCI PM state transition (to/from D3).

Moving the PCI-specific parts of the EHCI driver into their own file created a few issues ... notably on resume paths which (like swsusp) require re-initializing the controller. This patch: - Splits the EHCI startup code into run-once HCD setup code and separate "init the hardware" reinit code. (That reinit code is a superset of the "early usb handoff" code.) - Then it makes the PCI init code run both, and the resume code only run the reinit code. - It also removes needless pci wrappers around EHCI start/stop methods. - Removes a byteswap issue that would be seen on big-endian hardware. The HCD glue still doesn't actually provide a good way to do all this run-one init stuff in one place though. Signed-off-by:

This cleans up the recent updates to EHCI PCI support: - Gets rid of checks for "is this a PCI device", they're no longer needed since this is now all PCI-only code. - Reduce log spamming: MWI is only interesting in the atypical case that it can actually be used. - Whitespace cleanup, as appropriate for a new file with no other pending patches. So other than that minor logging change, no functional updates. Signed-off-by: -

This fixes some bugs in EHCI suspend/resume that joined us over the past few releases (as usbcore, PCI, pmcore, and other components evolved): - Removes suspend and resume recursion from the EHCI driver, getting rid of the USB_SUSPEND special casing. - Updates the wakeup mechanism to work again; there's a newish usbcore call it needs to use. - Provide simpler tests for "do we need to restart from scratch", to address another case where PCI Vaux was lost. (In this case it was restoring a swsusp snapshot, but there could be others.) Un-exports a symbol that was temporarily exported. A notable change from previous version is that this doesn't move the spinlock init, so there's still a resume/reinit path bug. Signed-off-by: -

When attempting to hotadd a PCI card with a bridge on it, I saw the kernel reporting resource collision errors even when there were really no collisions. The problem is that the code doesn't skip over "invalid" resources with their resource type flag not set. Others have reported similar problems at boot time and for non-bridge PCI card hotplug too, where the code flags a resource collision for disabled ROMs. This patch fixes both problems. Signed-off-by:

Per the PCI Express spec, the power-fault-detected bit in the slot status register can be set anytime hardware detects a power fault, regardless of whether the slot has a device populated in it or not. This bit is sticky and must be explicitly cleared. This patch is needed to allow hot-add after such a power fault has been detected. Signed-off-by:

Fix a bug where setting the low fan speed limits will not work if no data was ever read through the sysfs interface and the fan clock dividers have not been explicitely set yet either. The reason is that data->fan_div[nr] may currently be used before it is initialized from the chip register values. The fix is to explicitely initialize data->fan_div[nr] before using it. Bug reported, and fix tested, by Nicolas Mailhot. Signed-off-by:

Commit 7d24f0b8 fixed bugs in the ppc64 SLB miss handler with respect to hugepage handling, and in the process tweaked the semantics of the hugepage address masks in mm_context_t. Unfortunately, it left out a couple of necessary changes to go with that change. First, the in_hugepage_area() macro was not updated to match, second prepare_hugepage_range() was not updated to correctly handle hugepages regions which straddled the 4GB point. The latter appears only to cause process-hangs when attempting to map such a region, but the former can cause oopses if a get_user_pages() is triggered at the wrong point. This patch addresses both bugs. Signed-off-by:

If unregister_console() is inadvertently called while no consoles are registered, it will crash trying to dereference NULL pointer. It is necessary to fix that because register_console() provides no indication that it actually registered the console passed in. In fact, it may well decide not to register it based on various things... (akpm: It'd be better to make register_console() return something and fix the callers. All 106 of them...) Signed-off-by:

When non-leader thread does exec, de_thread adds old leader to the init's ->children list in EXIT_ZOMBIE state and drops tasklist_lock. This means that release_task(leader) in de_thread() is racy vs do_wait() from init task. I think de_thread() should set old leader's state to EXIT_DEAD instead. Signed-off-by:

Fix a bug in kprobes that can cause an Oops or even a crash when a return probe is installed on one of the following functions: sys_execve, do_execve, load_*_binary, flush_old_exec, or flush_thread. The fix is to remove the call to kprobe_flush_task() in flush_thread(). This fix has been tested on all architectures for which the return-probes feature has been implemented (i386, x86_64, ppc64, ia64). Please apply. BACKGROUND Up to now, we have called kprobe_flush_task() under two situations: when a task exits, and when it execs. Flushing kretprobe_instances on exit is correct because (a) do_exit() doesn't return, and (b) one or more return-probed functions may be active when a task calls do_exit(). Neither is the case for sys_execve() and its callees. Initially, the mistaken call to kprobe_flush_task() on exec was harmless because we put the "real" return address of each active probed function back in the stack, just to be safe, when we recycled its kretprobe_instance. When support for ppc64 and ia64 was added, this safety measure couldn't be employed, and was eventually dropped even for i386 and x86_64. sys_execve() and its callees were informally blacklisted for return probes until this fix was developed.

Update comments (only) on page_table_lock and mmap_sem in arch/powerpc.

The follow_page changes in get_futex_key have left it with two almost identical blocks, when handling the rare case of a futex in a nonlinear vma. get_user_pages will itself do that follow_page, and its additional find_extend_vma is hardly any overhead since the vma is already cached. Let's just delete the follow_page block and let get_user_pages do it. Signed-off-by:

Closer attention to the arithmetic shows that neither ppc64 nor sparc really uses one page for multiple page tables: how on earth could they, while pte_alloc_one returns just a struct page pointer, with no offset? Well, arm26 manages it by returning a pte_t pointer cast to a struct page pointer, harumph, then compensating in its pmd_populate. But arm26 is never SMP, so it's not a problem for split ptlock either. And the PA-RISC situation has been recently improved: CONFIG_PA20 works without the 16-byte alignment which inflated its spinlock_t. But the current union of spinlock_t with private does make the 7xxx struct page significantly larger, even without debug, so disable its split ptlock. Signed-off-by:

There was some confusion about the different zone usage, this should fix up the resulting mess in the GFP zonemask handling. The different zone usage is still confusing (it's very easy to mix up the individual zone numbers with the GFP zone _list_ numbers), so we might want to clean up some of this in the future, but in the meantime this should fix the actual problems.
