Instead of having board code poke directly into the MPP configuration registers, and separately calling orion5x_gpio_set_valid_pins() to indicate which MPP pins can be used as GPIO pins, introduce a helper function for configuring the roles of each of the MPP pins, and have that helper function handle gpio validity internally.

It makes no sense to do PCIe WA window setup in the individual board support files while the decision whether or not to use the PCIe WA access method is made in a different place, in the PCIe support code. This patch moves the configuration of a PCIe WA window from the individual Orion board support files to the central Orion PCIe support code.

This patch moves initialisation of EHCI/I2C/UART platform devices from the common orion5x_init() into the board support code. The rationale behind this is that only the board support code knows whether certain peripherals have been brought out on the board, and not initialising peripherals that haven't been brought out is desirable for example: - to reduce user confusion (e.g. seeing both 'eth0' and 'eth1' appear while there is only one ethernet port on the board); and - to allow for future power savings (peripherals that have not been brought out can be clock gated off entirely).

Make it clear that Orion top-level IRQs are level-triggered. This means that we don't need an ->ack() handler, or at least, we don't need the ->ack() handler (or the acking part of the ->mask_ack() handler) to actually do anything. Given that, we might as well point our ->mask_ack() handler at the ->mask() handler instead of providing a dummy ->ack() handler, since providing a ->mask_ack() handler on level IRQ sources will prevent ->ack() from ever being called.

The DRAM base address and size fields in the CPU's MBUS bridge have 64KiB granularity, instead of the currently used 16MiB. Since all of the currently supported MBUS peripherals support 64KiB granularity as well, this patch changes the Orion address map code to stop rounding base addresses down and sizes up to multiples of 16MiB.

Currently, Orion window setup uses hardcoded window indexes for each of the boot/cs0/cs1/cs2/PCIe WA windows. The static window allocation used can clash if board support code will ever attempt to configure both a dev2 and a PCIe WA window, as both of those use CPU mbus window #7 at present. This patch keeps track of the last used window, and opens subsequently requested windows sequentially, starting from 4. (Windows 0-3 are used as MEM/IO windows for the PCI/PCIe buses.)

The implementation for memory copy functions on ARM had a (disabled) provision for aligning the source pointer before loading registers with data. Turns out that aligning the _destination_ pointer is much more useful, as the read side is already sufficiently helped with the use of preload. So this changes the definition of the CALGN() macro to target the destination pointer instead, and turns it on for Feroceon processors where the gain is very noticeable.

The inline assembly in drivers/watchdog/hpwdt.c was incredibly broken, and included all the function prologue and epilogue stuff, even though it was itself then inside a C function where the compiler would add its own prologue and epilogue on top of it all. This then just _happened_ to work if you had exactly the right compiler version and exactly the right compiler flags, so that gcc just happened to not create any prologue at all (the gcc-generated epilogue wouldn't matter, since it would never be reached). But the more proper way to fix it is to simply not do this. Move the inline asm to the top level, with no surrounding function at all (the better alternative would be to remove the prologue and make it actually use proper description of the arguments to the inline asm, but that's a bigger change than the one I'm willing to make right now).

The driver expected a *virtual* address in the IDE platform device's memory resource and didn't request the memory region for the register block.

KAMEZAWA Hiroyuki and Oleg Nesterov point out that since the commit 557ed1fa ("remove ZERO_PAGE") removed the ZERO_PAGE from the VM mappings, any users of get_user_pages() will generally now populate the VM with real empty pages needlessly. We used to get the ZERO_PAGE when we did the "handle_mm_fault()", but since fault handling no longer uses ZERO_PAGE for new anonymous pages, we now need to handle that special case in follow_page() instead. In particular, the removal of ZERO_PAGE effectively removed the core file writing optimization where we would skip writing pages that had not been populated at all, and increased memory pressure a lot by allocating all those useless newly zeroed pages. This reinstates the optimization by making the unmapped PTE case the same as for a non-existent page table, which already did this correctly. While at it, this also fixes the XIP case for follow_page(), where the caller could not differentiate between the case of a page that simply could not be used (because it had no "struct page" associated with it) and a page that just wasn't mapped. We do that by simply returning an error pointer for pages that could not be turned into a "struct page *". The error is arbitrarily picked to be EFAULT, since that was what get_user_pages() already used for the equivalent IO-mapped page case. [ Also removed an impossible test for pte_offset_map_lock() failing: that's not how that function works ] Acked-by: NOleg Nesterov <oleg@tv-sign.ru> Acked-by: NNick Piggin <npiggin@suse.de> Cc: KAMEZAWA Hiroyuki <kamezawa.hiroyu@jp.fujitsu.com> Cc: Hugh Dickins <hugh@veritas.com> Cc: Andrew Morton <akpm@linux-foundation.org> Cc: Ingo Molnar <mingo@elte.hu> Cc: Roland McGrath <roland@redhat.com> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

This patch corrects the incorrect value of per process run-queue wait time reported by delay statistics. The anomaly was due to the following reason. When a process leaves the CPU and immediately starts waiting for CPU on the runqueue (which means it remains in the TASK_RUNNABLE state), the time of re-entry into the run-queue is never recorded. Due to this, the waiting time on the runqueue from this point of re-entry upto the next time it hits the CPU is not accounted for. This is solved by recording the time of re-entry of a process leaving the CPU in the sched_info_depart() function IF the process will go back to waiting on the run-queue. This IF condition is verified by checking whether the process is still in the TASK_RUNNABLE state. The patch was tested on 2.6.26-rc6 using two simple CPU hog programs. The values noted prior to the fix did not account for the time spent on the runqueue waiting. After the fix, the correct values were reported back to user space.
