1) Allow differently-ordered trip points 2) Change acpi_thermal_check to always call acpi_thermal_active (to allow that function to turn off active cooling if it wants 3) Properly activate active cooling devices

This just adds an if switch to irq_balance which the compiler optimises away anyway.

This patch that adds a prctl so that processes can set their floating-point exception mode on PPC and on PPC64. We need this because the FP exception mode is controlled by bits in the machine state register, which can only be accessed by the kernel, and because the exception mode setting interacts with the lazy FPU save/restore that the kernel does.

The patch allows userspace to issue printk's, via sys_syslog(). The main use of this is within hpa's klibc - initial userspace needs a way of logging information and this API allows that information to be captured into the printk ringbuffer. It ends up in /var/log/messages. Messages are truncated at 1024 characters by printk's vsprintf(). Requires CAP_SYS_ADMIN.

- I changed the sector_t thing in max_block to use davem's approach. I agree with Anton, but making it explicit doesn't hurt. - Remove a dead comment in copy_strings. Old stuff: - Remove the IO error warning in end_buffer_io_sync(). Failed READA attempts trigger it. - Emit a warning when an ext2 is mounting an ext3 filesystem. We have had quite a few problem reports related to this, mainly arising from initrd problems. And mount(8) tends to report the fstype from /etc/fstab rather than reporting what has really happened. Fixes some bogosity which I added to max_block(): - `size' doesn't need to be sector_t - `retval' should not be initialised to "~0UL" because that is 0x00000000ffffffff with 64-bit sector_t. - Allocate task_structs with GFP_KERNEL, as discussed. - Convert the EXPORT_SYMBOL for generic_file_direct_IO() to EXPORT_SYMBOL_GPL. That was only exported as a practicality for the raw driver. - Make the loop thread run balance_dirty_pages() after dirtying the backing file. So it will perform writeback of the backing file when dirty memory levels are high. Export balance_dirty_pages to GPL modules for this. This makes loop work a lot better - I suspect it broke when callers of balance_dirty_pages() started writing back only their own queue. There are many page allocation failures under heavy loop writeout. Coming from blk_queue_bounce()'s allocation from the page_pool mempool. So... - Disable page allocation warnings around the initial atomic allocation attempt in mempool_alloc() - the one where __GFP_WAIT and __GFP_IO were turned off. That one can easily fail. - Add some commentary in block_write_full_page()

get_page_state() is showing up on profiles on some big machines. It is a quite expensive function and it is being called too often. The patch replaces the hardwired RATELIMIT_PAGES with a calculated amount based on the amount of memory in the machine and the number of CPUs.

include/linux/prefetch.h does a strange thing: if the arch doesn't have the prefectch functions, this header defines no-op version of them and then defines ARCH_HAS_PREFETCH. So there's no way for mainline code to know if the architecture *really* has prefetch instructions. This information loss is unfortunate. Examples: for (i = 0; i < N; i++) prefetch(foo[i]); Problem is, if `prefetch' is a no-op, the compiler will still generate an empty busy-wait loop. Which it must do. We need to know the truth about ARCH_HAS_PREFETCH to correctly elide that loop.

This adds two new clone() flags: CLONE_SETTLS => if present then the third clone() syscall parameter is the new TLS. CLONE_SETTID => if present then the child TID is written to the address specified by the fourth clone() parameter. the new parameters are handled in a safe way, clone() returns -EFAULT or -EINVAL if there's some problem with them.

Here is a trivial bug fix for blkdev_reread_part() in 2.5.31. Without this fix, "fdisk" hangs with following messages: Calling ioctl() to re-read partition table. WARNING: Re-reading the partition table failed with error 16: Device or resource busy. The kernel still uses the old table. The new table will be used at the next reboot.

Change all iterators of devices to: - use list_for_each - check return of get_device_locked - don't break until we hold the lock if we get an error When a device's reference count hits 0, remove it from all lists, including bus and driver lists. Between the iterator algorithm and the guaranteed removal from the lists, there should never be a device in a list with a reference count of 0. So, whenever we're iterating over the lists, we'll always have a valid device. We don't decrement the refcount until the next iteration of the loop, so we're also guaranteed to get the correct next item in the list.

- teaches the shared "hcd" code to set urb->*_dma whenever the device driver didn't, by creating singleshot mappings.

- teaches the hardware-specific code to use urb->*_dma instead of creating mappings. (And tells ohci-sa1111 to init its buffer pools.) EHCI and UHCI also eliminated duplicated state; all the HCDs are now a smidgeon smaller. Sanity checked by enumerating, including through a hub, and using a USB Ethernet adapter, with each of the three host controllers. Worth noting: this removes pci_dma_sync_single() calls from UHCI. On x86 (and some others) that's a NOP, but for UHCI on other platforms (rare except maybe on IA64, as I understand) this anticipates the upcoming patch to remove interrupt automagic. (I'll likely submit that after a Linus release that catches up to your USB tree. :)

When adding to the global device list, we were adding devices just after their parent, while we wanted to add them just before. That way when we iterate over the list on suspend and shutdown, we'll hit all children before the parents. Make sure dev->driver_list and dev->bus_list are initialized when the device is registered Remove device from global and parent's list if registration failed.

This patch to 2.5.31 pushes "Networking options" and "Network device support" together for all architectures that have them. They shouldn't be split apart by Telephony, I2O, Fusion, etc.

This old __per_cpu_data define wasn't enough if an arch wants to use the gcc __thread prefix (thread local storage), which needs to go *before* the type in the definition. So we have to go for a DECLARE macro, and while we're there, separate DECLARE and DEFINE, as definitions of per-cpu data cannot live in modules. This also means that accidental direct references to per-cpu variables will be caught at compile time.

This makes introduces get_cpu_var()/put_cpu_var() which gets a per-cpu variable and disables preemption, and renames the (unsafe under preemption) "this_cpu()" macro to __get_cpu_var(). It also deletes the redundant definitions in linux/smp.h.

This moves the early ioremap call to after cpu_online_map is initialized. Note everything is wrapped in clustered_apic_mode, so should be safe.

When you reverted the stringify changes I sent last time, you missed removing a comment, which is now grossly wrong. This patch finishes the job.
