Rather than unlock/re-lock for every write access, unlock a GPIO when it is requested and re-lock it when it is freed. As a result, the GPIO helper functions no longer have to deal with unlocking and re-locking the register. In addition, only unlock a specific GPIO rather than unlocking the entire GPIO bank as before.

Drop the " gpio" suffix after the pl061 irq_chip name: this is only confusing: an irqchip name should be a single, short, simple string that looks nice in /proc/interrupts. Drop the nameing of each individual IRQ to "pl061" - I think this naming function is for naming the IRQ line, not for boilerplating them all with the name of the parent controller, which is already known from the .name field of the irq_chip.

Pull parisc updates from Helge Deller: "The three major changes in this patchset is a implementation for flexible userspace memory maps, cache-flushing fixes (again), and a long-discussed ABI change to make EWOULDBLOCK the same value as EAGAIN. parisc has been the only platform where we had EWOULDBLOCK != EAGAIN to keep HP-UX compatibility. Since we will probably never implement full HP-UX support, we prefer to drop this compatibility to make it easier for us with Linux userspace programs which mostly never checked for both values. We don't expect major fall-outs because of this change, and if we face some, we will simply rebuild the necessary applications in the debian archives" * 'parisc-3.14' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux: parisc: add flexible mmap memory layout support parisc: Make EWOULDBLOCK be equal to EAGAIN on parisc parisc: convert uapi/asm/stat.h to use native types only parisc: wire up sched_setattr and sched_getattr parisc: fix cache-flushing parisc/sti_console: prefer Linux fonts over built-in ROM fonts

HPFS needs to load 4 consecutive 512-byte sectors when accessing the directory nodes or bitmaps. We can't switch to 2048-byte block size because files are allocated in the units of 512-byte sectors. Previously, the driver would allocate a 2048-byte area using kmalloc, copy the data from four buffers to this area and eventually copy them back if they were modified. In the current implementation of the buffer cache, buffers are allocated in the pagecache. That means that 4 consecutive 512-byte buffers are stored in consecutive areas in the kernel address space. So, we don't need to allocate extra memory and copy the content of the buffers there. This patch optimizes the code to avoid copying the buffers. It checks if the four buffers are stored in contiguous memory - if they are not, it falls back to allocating a 2048-byte area and copying data there.

Previously, hpfs scanned all bitmaps each time the user asked for free space using statfs. This patch changes it so that hpfs scans the bitmaps only once, remembes the free space and on next invocation of statfs it returns the value instantly. New versions of wine are hammering on the statfs syscall very heavily, making some games unplayable when they're stored on hpfs, with load times in minutes. This should be backported to the stable kernels because it fixes user-visible problem (excessive level load times in wine).

Revert commit ef83b078 "PCI: Remove from bus_list and release resources in pci_release_dev()" that made some nasty race conditions become possible. For example, if a Thunderbolt link is unplugged and then replugged immediately, the pci_release_dev() resulting from the hot-remove code path may be racing with the hot-add code path which after that commit causes various kinds of breakage to happen (up to and including a hard crash of the whole system). Moreover, the problem that commit ef83b078 attempted to address cannot happen any more after commit 8a4c5c32 "PCI: Check parent kobject in pci_destroy_dev()", because pci_destroy_dev() will now return immediately if it has already been executed for the given device. Note, however, that the invocation of msi_remove_pci_irq_vectors() removed by commit ef83b078 from pci_free_resources() along with the other changes made by it is not added back because of subsequent code changes depending on that modification.
