* [IA64] fix Kprobes reentrancyAnil S Keshavamurthy2007-05-11
| | | | | | | | | | | | | | | | | | In case of reentrance i.e when a probe handler calls a functions which inturn has a probe, we save a previous kprobe information and just single step the reentrant probe without calling the actual probe handler. During this reentracy period, if an interrupt occurs and if probe happens to trigger in the inturrupt path, then we were corrupting the previous kprobe( as we were overriding the previous kprobe info) info their by crashing the system. This patch fixes this issues by having a an array of previous kprobe info struct(with the array size of 2). This similar technique is not needed on i386 and x86_64 because by default interrupts are turn off in the break/int3 exception handler.

* [IA64] SN: validate smp_affinity mask on intr redirectJohn Keller2007-05-11
| | | | | | | | | | | | On SN, only allow one bit to be set in the smp_affinty mask when redirecting an interrupt. Currently setting multiple bits is allowed, but only the first bit is used in determining the CPU to redirect to. This has caused confusion among some customers.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add an InfiniBand driver for Mellanox ConnectX adapters. Because these adapters can also be used as ethernet NICs and Fibre Channel HBAs, the driver is split into two modules: mlx4_core: Handles low-level things like device initialization and processing firmware commands. Also controls resource allocation so that the InfiniBand, ethernet and FC functions can share a device without stepping on each other. mlx4_ib: Handles InfiniBand-specific things; plugs into the InfiniBand midlayer.

| * IB: Put rlimit accounting struct in struct ib_umemRoland Dreier2007-05-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When memory pinned with ib_umem_get() is released, ib_umem_release() needs to subtract the amount of memory being unpinned from mm->locked_vm. However, ib_umem_release() may be called with mm->mmap_sem already held for writing if the memory is being released as part of an munmap() call, so it is sometimes necessary to defer this accounting into a workqueue. However, the work struct used to defer this accounting is dynamically allocated before it is queued, so there is the possibility of failing that allocation. If the allocation fails, then ib_umem_release has no choice except to bail out and leave the process with a permanently elevated locked_vm. Fix this by allocating the structure to defer accounting as part of the original struct ib_umem, so there's no possibility of failing a later allocation if creating the struct ib_umem and pinning memory succeeds.

| * IB/uverbs: Export ib_umem_get()/ib_umem_release() to modulesRoland Dreier2007-05-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Export ib_umem_get()/ib_umem_release() and put low-level drivers in control of when to call ib_umem_get() to pin and DMA map userspace, rather than always calling it in ib_uverbs_reg_mr() before calling the low-level driver's reg_user_mr method. Also move these functions to be in the ib_core module instead of ib_uverbs, so that driver modules using them do not depend on ib_uverbs. This has a number of advantages: - It is better design from the standpoint of making generic code a library that can be used or overridden by device-specific code as the details of specific devices dictate. - Drivers that do not need to pin userspace memory regions do not need to take the performance hit of calling ib_mem_get(). For example, although I have not tried to implement it in this patch, the ipath driver should be able to avoid pinning memory and just use copy_{to,from}_user() to access userspace memory regions. - Buffers that need special mapping treatment can be identified by the low-level driver. For example, it may be possible to solve some Altix-specific memory ordering issues with mthca CQs in userspace by mapping CQ buffers with extra flags. - Drivers that need to pin and DMA map userspace memory for things other than memory regions can use ib_umem_get() directly, instead of hacks using extra parameters to their reg_phys_mr method. For example, the mlx4 driver that is pending being merged needs to pin and DMA map QP and CQ buffers, but it does not need to create a memory key for these buffers. So the cleanest solution is for mlx4 to call ib_umem_get() in the create_qp and create_cq methods. Signed-off-by: Roland Dreier <rolandd@cisco.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It is preferable to group drivers by usage (net, scsi, ATA, ...) than by bus. When reviewing drivers, the [PCI|USB|PCMCIA|...] maintainer is probably less qualified on networking issues than a networking maintainer. Also, from a practical standpoint, chips often appear on multiple buses, which is why we do not put drivers into drivers/pci/net.

Freeze and thaw didn't switch the ADMA-specific interrupts on or off, and more critically the irq_clear function didn't respect the restriction that the notifier clear registers for both ports have to be written at the same time even when only one port is being cleared. This could result in timeouts on one port when error handling (i.e. as a result of hotplug) occurred on the other port. As well, this fixes some issues in the interrupt handler: we shouldn't check any ADMA status if the port has ADMA switched off because of an ATAPI device, and it also checks to see if any ADMA interrupt has been raised even when we are in port-register mode.

However, Promise's BIOS and Linux driver both get the order right. I investigated Promise's Linux driver (v1.01.0.23), and found that it explicitly changes the mapping from logical port number to ATA engine MMIO address on the SATAII TX4 cards. It does this on all SATAII TX4 cards, without inspecting revision etc. The SATAII TX2plus cards continue to use the same mapping that was used for the first-generation chips. This patch updates sata_promise to use the new port number to ATA engine mapping on SATAII TX4 cards, which fixes the drive enumeration order problem on those cards. Tested on several 1st and 2nd generation TX2plus and TX4 chips. Signed-off-by: Mikael Pettersson <mikpe@it.uu.se> Signed-off-by: Jeff Garzik <jeff@garzik.org>

Unfortunately not completing the qc:s causes them to always time out on error, which is wrong and has nasty side-effects. This patch updates pdc_error_intr() to call ata_port_abort(), similar to ahci and sata_sil24. Doing this is important as it makes EH see the original error and not a bogus timeout.

Quoth Neil Brown: "It causes an oops when auto-detecting raid arrays, and it doesn't seem easy to fix. The array may not be 'open' when do_md_run is called, so bdev->bd_disk might be NULL, so bd_set_size can oops. This whole approach of opening an md device before it has been assembled just seems to get more and more painful. I think I'm going to have to come up with something clever to provide both backward comparability with usage expectation, and sane integration into the rest of the kernel."

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Ejecting a PCMCIA IBM Token Ring card that has not had its dev->open() called will reliably trigger an uninitialized spinlock oops when spinlock debugging is enabled. The system then hangs, occasionally softlockup oopsing. Apparently ibmtr.c:tok_interrupt() doesn't expect to be called before tok_open(), but tok_interrupt() gets called anyway when the card is ejected. So, set an already-existing flag which causes tok_interrupt() to bail out early upon card ejection. Tested by inserting and removing the PCMCIA card several times.

Add CONFIG_IDE_PROC_FS (CONFIG_SCSI_PROC_FS rip-off) config option, disabling it makes IDE driver ~5 kB smaller (on x86-32).
