* sparse irq_desc[] array: core kernel and x86 changesYinghai Lu2008-12-08
| | | | | | | | | | | | | | | | | | | | | Impact: new feature Problem on distro kernels: irq_desc[NR_IRQS] takes megabytes of RAM with NR_CPUS set to large values. The goal is to be able to scale up to much larger NR_IRQS value without impacting the (important) common case. To solve this, we generalize irq_desc[NR_IRQS] to an (optional) array of irq_desc pointers. When CONFIG_SPARSE_IRQ=y is used, we use kzalloc_node to get irq_desc, this also makes the IRQ descriptors NUMA-local (to the site that calls request_irq()). This gets rid of the irq_cfg[] static array on x86 as well: irq_cfg now uses desc->chip_data for x86 to store irq_cfg.

* Revert "ACPI: battery: Convert discharge energy rate to current properly"Linus Torvalds2008-12-05
| | | | | | | | | | | | | | | | | | | This reverts commit 558073dd56707864f09d563b64e7c37c021e89d2, along with the failed try to fix the regression it caused ("ACPI: Fix ACPI battery regression introduced by commit 558073"), which just made things worse. Commit aaad077638be1a25871bcae5e43952d6b63abfca (that failed "Fix ACPI battery regression") got the voltage conversion confused, and fixed the problem with Rafael's battery monitor apparently just by mistake. So revert them both, getting us back to the 2.6.27 state in this, and let's revisit it when people understand what's going on. Noted-by: Paul Martin <pm@debian.org> Requested-by: Rafael J.

When stacking devices (LVM over MD over SCSI) some of the request queue parameters are not set up correctly in some cases by default, namely max_segment_size and and seg_boundary mask. If you create MD device over SCSI, these attributes are zeroed. Problem become when there is over this mapping next device-mapper mapping - queue attributes are set in DM this way: request_queue max_segment_size seg_boundary_mask SCSI 65536 0xffffffff MD RAID1 0 0 LVM 65536 -1 (64bit) Unfortunately bio_add_page (resp. bio_phys_segments) calculates number of physical segments according to these parameters. During the generic_make_request() is segment cout recalculated and can increase bio->bi_phys_segments count over the allowed limit. (After bio_clone() in stack operation.) Thi is specially problem in CCISS driver, where it produce OOPS here BUG_ON(creq->nr_phys_segments > MAXSGENTRIES); (MAXSEGENTRIES is 31 by default.) Sometimes even this command is enough to cause oops: dd iflag=direct if=/dev/<vg>/<lv> of=/dev/null bs=128000 count=10 This command generates bios with 250 sectors, allocated in 32 4k-pages (last page uses only 1024 bytes). For LVM layer, it allocates bio with 31 segments (still OK for CCISS), unfortunatelly on lower layer it is recalculated to 32 segments and this violates CCISS restriction and triggers BUG_ON(). The patch tries to fix it by: * initializing attributes above in queue request constructor blk_queue_make_request() * make sure that blk_queue_stack_limits() inherits setting (DM uses its own function to set the limits because it blk_queue_stack_limits() was introduced later. It should probably switch to use generic stack limit function too.) * sets the default seg_boundary value in one place (blkdev.h) * use this mask as default in DM (instead of -1, which differs in 64bit) Bugs related to this: https://bugzilla.redhat.com/show_bug.cgi?id=471639 http://bugzilla.kernel.org/show_bug.cgi?id=8672 Signed-off-by: Milan Broz <mbroz@redhat.com> Reviewed-by: Alasdair G Kergon <agk@redhat.com> Cc: Neil Brown <neilb@suse.de> Cc: FUJITA Tomonori <fujita.tomonori@lab.ntt.co.jp> Cc: Tejun Heo <htejun@gmail.com> Cc: Mike Miller <mike.miller@hp.com> Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
* | iTCO_wdt: fix typo when setting TCO_EN bitLinus Torvalds2008-12-03
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | The code used '&= 0x00002000' when it tried to set the TCO_EN bit, which obviously didn't set that bit at all, but instead just reset all the other bits in the SMI_EN register. This bug seemingly caused various random behavior, with Frans Pop reporting that X.org just silently hung at startup and Rafael Wysocki reports the fan spinning with full speed. See http://lkml.org/lkml/2008/12/3/178 http://bugzilla.kernel.org/show_bug.cgi?id=12162 The problem seems to have been triggered by "[WATCHDOG] iTCO_wdt : problem with rebooting on new ICH9 based motherboards" (commit 7cd5b08be3c489df11b559fef210b81133764ad4), but the bogus code existed before that too (in the "supermicro_old_pre_stop()" function), it just apparently never showed up due to different logic. In that commit the broken code got moved around and now gets executed much more. Reported-by: Rafael J.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the "hpwdt" module is loaded (even if the /dev/watchdog device is not opened), then kdump does not work. The panic kernel either does not start at all or crash in various places. The problem is that hpwdt_pretimeout is registered with register_die_notifier() with the highest possible priority. Because it returns NOTIFY_STOP, the crash_nmi_callback which is also registered with register_die_notifier() is never executed. This causes the shutdown of other CPUs to fail. Reverting the order is no option: The crash_nmi_callback executes HLT and so never returns normally. Because of that, it must be executed as last notifier, which currently is done. So, that patch returns NOTIFY_OK to keep the crash_nmi_callback executed.

The issue prior to this though was we were unmapping a smaller amount which the prior DMA patch fixed. Signed-off-by: Bennyam Malavazi <Bennyam.Malavazi@atheros.com> Signed-off-by: Luis R.

We were pci_unmap_single()'ing less bytes than what we called for with pci_map_single() and as such we were starving the swiotlb from its 64MB amount of bounce buffers. We remain consistent and now always use sc->rxbufsize for RX. While at it we update the beacon DMA maps as well to only use the data portion of the skb, previous to this we were pci_map_single()'ing more data for beaconing than what we tell the hardware it can use, therefore pushing more iotlb abuse. Still not sure why this is so easily triggerable on MacBook Pro 3.1, it may be the hardware configuration tends to use more memory > 3GB mark for DMA.

I asked around, and he's right, there may be platforms that do not allow passing such such an address to the DMA API functions. This patch changes it by using the proper dma_sync_single_range_for_cpu API invented for this purpose. Cc: Luis R.

The init sequence is different and the interrupt mask lacks some bits present in the VSC8244. Rather than making a copy of the existing VSC234x config_intr function and change one constant, I modify it to select the interrupt mask based on which driver is calling it. This lets it be used by both drivers. Signed-off-by: Trent Piepho <tpiepho@freescale.com> Signed-off-by: David S. Miller <davem@davemloft.net>
