This is a port of libata's pata_cs5536.c (written by Martin K. Petersen) to IDE subsystem. Changes done while at it: * Reprogram PIO/MWDMA timings if needed before and after DMA transfer (chipset uses shared PIO/MWDMA timings). * Fix cable detection to report 80-wires cable if BIOS set it for any device on a port (IDE core will do drive-side cable detection later). * Don't disable UDMA while programming PIO timings. * Simplify PCI/MSR support. Pros of having IDE host driver in addition to libata's one: * IDE is much lighter than SCSI+libata, the host driver itself is also a bit smaller: text data bss dec hex filename 1261 496 4 1761 6e1 drivers/ata/pata_cs5536.o 1242 128 4 1374 55e drivers/ide/cs5536.o * This allows use of IDE features which are unavailable under libata. v2: * Fixes per review from Sergei: - simplify dependency check in Kconfig - use IDE_DRV_MASK also for ->drive_data - disable UDMA when programming MWDMA - program new DTC timings only when necessary - fix printk() level in cs5536_init_one() * Fix patch description according to comments from Alan and Sergei. v3: * Smarter masking of UDMA bits per Sergei's suggestion.

This essentially reverts commit 8edb08ca. It downgraded our mmap semaphore to a read-lock while mlocking pages, in order to allow other threads (and external accesses like "ps" et al) to walk the vma lists and take page faults etc. Which is a nice idea, but the implementation does not work. Because we cannot upgrade the lock back to a write lock without releasing the mmap semaphore, the code had to release the lock entirely and then re-take it as a writelock. However, that meant that the caller possibly lost the vma chain that it was following, since now another thread could come in and mmap/munmap the range. The code tried to work around that by just looking up the vma again and erroring out if that happened, but quite frankly, that was just a buggy hack that doesn't actually protect against anything (the other thread could just have replaced the vma with another one instead of totally unmapping it). The only way to downgrade to a read map _reliably_ is to do it at the end, which is likely the right thing to do: do all the 'vma' operations with the write-lock held, then downgrade to a read after completing them all, and then do the "populate the newly mlocked regions" while holding just the read lock. And then just drop the read-lock and return to user space. The (perhaps somewhat simpler) alternative is to just make all the callers of mlock_vma_pages_range() know that the mmap lock got dropped, and just re-grab the mmap semaphore if it needs to mlock more than one vma region. So we can do this "downgrade mmap sem while populating mlocked regions" thing right, but the way it was done here was absolutely not correct. Thus the revert, in the expectation that we will do it all correctly some day.

Fix an off-by-two memory error in console selection. The loop below goes from sel_start to sel_end (inclusive), so it writes one more character. This one more character was added to the allocated size (+1), but it was not multiplied by an UTF-8 multiplier. This patch fixes a memory corruption when UTF-8 console is used and the user selects a few characters, all of them 3-byte in UTF-8 (for example a frame line). When memory redzones are enabled, a redzone corruption is reported. When they are not enabled, trashing of random memory occurs.

The mmap_region() code would temporarily set the VM_ACCOUNT flag for anonymous shared mappings just to inform shmem_zero_setup() that it should enable accounting for the resulting shm object. It would then clear the flag after calling ->mmap (for the /dev/zero case) or doing shmem_zero_setup() (for the MAP_ANON case). This just resulted in vma merge issues, but also made for just unnecessary confusion. Use the already-existing VM_NORESERVE flag for this instead, and let shmem_{zero|file}_setup() just figure it out from that. This also happens to make it obvious that the new DRI2 GEM layer uses a non-reserving backing store for its object allocation - which is quite possibly not intentional. But since I didn't want to change semantics in this patch, I left it alone, and just updated the caller to use the new flag semantics. Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

As the mmap handler gets called under mmap_sem, and we may grab mmap_sem elsewhere under the socket lock to access user data, we should avoid grabbing the socket lock in the mmap handler.

Impact: fix CPU hotplug hang on Power6 testbox On architectures that support offlining all cpus (at least powerpc/pseries), hot-unpluging the tick_do_timer_cpu can result in a system hang. This comes from the fact that if the cpu going down happens to be the cpu doing the tick, then as the tick_do_timer_cpu handover happens after the cpu is dead (via the CPU_DEAD notification), we're left without ticks, jiffies are frozen and any task relying on timers (msleep, ...) is stuck. That's particularly the case for the cpu looping in __cpu_die() waiting for the dying cpu to be dead. This patch addresses this by having the tick_do_timer_cpu handover happen earlier during the CPU_DYING notification. For this, a new clockevent notification type is introduced (CLOCK_EVT_NOTIFY_CPU_DYING) which is triggered in hrtimer_cpu_notify().
