* MIPS: PowerTV: Use O(1) algorthm for phys_to_dma/dma_to_physDavid VomLehn2010-08-056-142/+529
| | | | | | | | | | | | | | | | | | | | | | | | Replace phys_to_dma()/dma_to_phys() looping algorithm with an O(1) algorithm The approach taken is inspired by the sparse memory implementation: take a certain number of high-order bits off the address them, use this as an index into a table containing an offset to the desired address and add it to the original value. There is a table for mapping physical addresses to DMA addresses and another one for the reverse mapping. The table sizes depend on how fine-grained the mappings need to be; Coarser granularity less to smaller tables. On a processor with 32-bit physical and DMA addresses, with 4 MIB granularity, memory usage is two 2048-byte arrays. Each 32-byte cache line thus covers 64 MiB of address space. Also, renames phys_to_bus() to phys_to_dma() and bus_to_phys() to dma_to_phys() to align with kernel usage.

* MIPS: BCM47xx: Really fix 128MB RAM problemHauke Mehrtens2010-08-051-8/+14
| | | | | | | | | | | | | | | | | | | The previous patch 4a86f2d27733f610e642649aca3e82e86fca9e22 (lmo) rsp. 84a6fcb368a080620d12fc4d79e07902dbee7335 (kernel.org) was wrong. The BCM47xx architecture maps the ram into a 128MB address space. It will be spaced there as often as goes into the 128MB. Detection tries to find the position where the same memory is found. When reading beyond 128MB the processor will throw an exception. If 128MB RAM is installed, it will not find a memory alias because it tries to read beyond the 128MB border. Now it just assumes 128MB installed ram if it can not find an alias.

| * ARM: 6279/1: highmem: fix SMP preemption bug in kmap_high_l1_viptGary King2010-07-301-5/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | smp_processor_id() must not be called from a preemptible context (this is checked by CONFIG_DEBUG_PREEMPT). kmap_high_l1_vipt() was doing so. This lead to a problem where the wrong per_cpu kmap_high_l1_vipt_depth could be incremented, causing a BUG_ON(*depth <= 0); in kunmap_high_l1_vipt(). The solution is to move the call to smp_processor_id() after the call to preempt_disable().

| | | | | | | | | | | | | | | | | | The ioread/iowrite accessors also need barriers as they're used in place of readl/writel et.al. in portable drivers.

| * ARM: 6273/1: Add barriers to the I/O accessors if ARM_DMA_MEM_BUFFERABLECatalin Marinas2010-07-291-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the coherent DMA buffers are mapped as Normal Non-cacheable (ARM_DMA_MEM_BUFFERABLE enabled), buffer accesses are no longer ordered with Device memory accesses causing failures in device drivers that do not use the mandatory memory barriers before starting a DMA transfer. LKML discussions led to the conclusion that such barriers have to be added to the I/O accessors: http://thread.gmane.org/gmane.linux.kernel/683509/focus=686153 http://thread.gmane.org/gmane.linux.ide/46414 http://thread.gmane.org/gmane.linux.kernel.cross-arch/5250 This patch introduces a wmb() barrier to the write*() I/O accessors to handle the situations where Normal Non-cacheable writes are still in the processor (or L2 cache controller) write buffer before a DMA transfer command is issued. For the read*() accessors, a rmb() is introduced after the I/O to avoid speculative loads where the driver polls for a DMA transfer ready bit.

| | | | | | | | | | | | | | | | | | | | | | This patch is in preparation for a subsequent patch which adds barriers to the I/O accessors. Since the mandatory barriers may do an L2 cache sync, this patch avoids a recursive call into l2x0_cache_sync() via the write*() accessors and wmb() and a call into l2x0_cache_sync() with the l2x0_lock held.

I'd missed updating the gate_vma handling in __get_user_pages(): that happens to use vm_normal_page() (nowadays failing on the zero page), yet reported success even when it failed to get a page - boom when access_process_vm() tried to copy that to its intermediate buffer. Fix this, resisting cleanups: in particular, leave it for now reporting success when not asked to get any pages - very probably safe to change, but let's not risk it without testing exposure. Why did ia64 crash with 16kB pages, but succeed with 64kB pages? Because setup_gate() pads each 64kB of its gate area with zero pages.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The etr events switch-to-local and sync-check disable the synchronous clock and schedule a work queue that tries to get the clock back into sync. If another switch-to-local or sync-check event occurs while the work queue function etr_work_fn still runs the eacr.es bit and the clock_sync_word can become inconsistent because check_sync_clock only uses the clock_sync_word to determine if the clock is in sync or not. The second pass of the etr_work_fn will reset the eacr.es bit but will leave the clock_sync_word intact. Fix this race by moving the reset of the eacr.es bit into the switch-to-local and sync-check functions and by checking the eacr.es bit as well to decide if the clock needs to be synced.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In case user space is single stepped (PER) the program check handler claims too early that IRQs are enabled on the return path. Subsequent checks will notice that the IRQ mask in the PSW and what lockdep thinks the IRQ mask should be do not correlate and therefore will print a warning to the console and disable lockdep. Fix this by doing all the work within the correct context. Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>

Thus the driver interprets it badly, resulting in non-working PC beep. This patch adds a white-list for such a case; a white-list of known devices with working PC beep.

Since the current code assumes the new behavior, the pin-detection doesn't work relialby with these h/w. This patch adds a flag for indicating the old spec, and fixes the issue by checking the pin-detection explicitly for such hardware.

Instead, add the following validation condition: task->exit_state >= 0 to permit the access if the target task is dead and therefore unable to change its own credentials. Fix __task_cred()'s comment to: (1) discard the bit that says that the caller must prevent the target task from being deleted. That shouldn't need saying. (2) Add a comment indicating the result of __task_cred() should not be passed directly to get_cred(), but rather than get_task_cred() should be used instead. Also put a note into the documentation to enforce this point there too. Signed-off-by: David Howells <dhowells@redhat.com> Acked-by: Jiri Olsa <jolsa@redhat.com> Cc: Paul E.
