* [ARM] Fix some corner cases in new mm initialisationRussell King2005-11-172-12/+16
| | | | | | | | | | | | | | Document that the VMALLOC_END address must be aligned to 2MB since it must align with a PGD boundary. Allocate the vectors page early so that the flush_cache_all() later will cause any dirty cache lines in the direct mapping will be safely written back. Move the flush_cache_all() to the second local_flush_cache_tlb() and remove the now redundant first local_flush_cache_tlb(). Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* [ARM] __ioremap doesn't use 4th argumentRussell King2005-11-173-17/+16
| | | | | | | | The "align" argument in ARMs __ioremap is unused and provides a misleading expectation that it might do something. It doesn't. Remove it. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

| | | | | | | | | | | | Patch from Nicolas Pitre If 'old' and 'oldval' are different then 'res' never gets set. In that case, if ever %0 happened to contain anything but zero (rather likely) then the code will loop forever (or until another CPU just come along and change the atomic value to match 'old' which is rather unlikely).

* | [PATCH] powerpc: Fix sparsemem with memory holes [was Re: ppc64 oops..]Paul Mackerras2005-11-162-3/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch should fix the crashes we have been seeing on 64-bit powerpc systems with a memory hole when sparsemem is enabled. I'd appreciate it if people who know more about NUMA and sparsemem than me could look over it. There were two bugs. The first was that if NUMA was enabled but there was no NUMA information for the machine, the setup_nonnuma() function was adding a single region, assuming memory was contiguous. The second was that the loops in mem_init() and show_mem() assumed that all pages within the span of a pgdat were valid (had a valid struct page). I also fixed the incorrect setting of num_physpages that Mike Kravetz pointed out. Signed-off-by: Paul Mackerras <paulus@samba.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* | [PATCH] ia64: cpu_idle performance bug fixChen, Kenneth W2005-11-161-7/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Our performance validation on 2.6.15-rc1 caught a disastrous performance regression on ia64 with netperf (-98%) and volanomark (-58%) compares to previous kernel version 2.6.14-git7. See the following chart (result group 1 & 2). http://kernel-perf.sourceforge.net/results.machine_id=26.html We have root caused it to commit 64c7c8f88559624abdbe12b5da6502e8879f8d28 This changeset broke the ia64 task resched notification. In sched.c:resched_task(), a reschedule IPI is conditioned upon TIF_POLLING_NRFLAG. However, the above changeset unconditionally set the polling thread flag for idle tasks regardless whether pal_halt_light is in use or not. As a result, resched IPI is not sent from resched_task(). And since the default behavior on ia64 is to use pal_halt_light, we end up delaying the rescheduling task until next timer tick, and thus cause the performance regression. This fixes the performance bug. I'm glad our performance suite is turning up bad performance bug like this in time.

| * | [libata ahci] command completion fixes, improved debug msgsJeff Garzik2005-11-151-10/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | - Fix a regression in command completion, which prevented the restart of the DMA engine after the device throws an error. - Pack more hardware info into the port-reset error message. - Promote "welcome to our timeout" message from debug msg to normal printk.
| * | [libata] REQUEST SENSE handling fixesJeff Garzik2005-11-143-58/+43
| | | | | | | | | | | | | | | | | | | | | | | | - Move ATAPI check-condition handling out of the timeout handler - Use multi-qc-issue feature to issue REQUEST SENSE ATAPI PACKET command upon receiving an ATAPI check-condition. This cleans things up a lot, and eliminates a nasty recursion bug.
| * | [libata] minor fixes, new helpersJeff Garzik2005-11-142-8/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - in ata_dev_identify(), don't assume that all devices are either ATA or ATAPI. In the future, this code will see port multipliers and other devices. - make a debugging printk less verbose - add new helper ata_qc_reinit() - add new helper BPRINTK() and port flag ATA_FLAG_DEBUGMSG, for fine-grained debugging use.
| * | [libata] fix bugs in ATAPI padding DMA mapping codeJeff Garzik2005-11-141-5/+26
| | | | | | | | | | | | | | | | | | | | | The ATAPI pad-to-next-32bit-boundary code modifies the scatterlist's length variable, sometimes to zero. x86-64 platform would oops if a zero-length scatterlist entry was asked to be mapped. Work around this by ensuring that we never DMA-map a zero length buffer or SG entry.
| * | [libata ahci] error handling fixesJeff Garzik2005-11-141-5/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Needed to get ATAPI working. - dump hardware error bits, if hardware signals an error - only reset hardware during timeout if a command was active - call ata_qc_complete() with a fine-grained error mask. Needed so that atapi_qc_complete() can distinguish between device errors and other errors.
