Resetting the adapter causes the ServeRAID driver to exceed the max time allowed by the softlock watchdog. Resetting the hardware can easily require 30 or more seconds. To avoid the "BUG: soft lockup detected on CPU#0!" result, this patch adds a touch_nmi_watchdog() to the driver's MDELAY macro.

I wanted to add some BUG checks to scsi_prep_fn to make sure no one sends us a non-sg command, but this function is a horrible mess. So I decided to detangle the function and document what the valid cases are. While doing that I found that REQ_TYPE_SPECIAL commands aren't used by the SCSI layer anymore and we can get rid of the code handling them. The new structure of scsi_prep_fn is: (1) check if we're allowed to send this command (2) big switch on cmd_type. For the two valid types call into a function to set the command up, else error (3) code to handle error cases Because FS and BLOCK_PC commands are handled entirely separate after the patch this introduces a tiny amount of code duplication. This improves readabiulity though and will help to avoid the bidi command overhead for FS commands so it's a good thing. I've tested this on both sata and mptsas.

scsi_send_eh_cmnd is the last user of non-sg commands currently. This patch switches it to a one-element SG list. Also updates the kerneldoc comment for scsi_send_eh_cmnd to reflect reality while we're at it. Test on my mptsas card, but this should get testing with as many drivers as possible.

This patch adds an external function, sas_abort_task, to enable LLDDs to abort sas_tasks.

Since it often takes around 20-30 seconds to scan a scsi bus, it's highly advantageous to do this in parallel with other things. The bulk of this patch is ensuring that devices don't change numbering, and that all devices are discovered prior to trying to start init. For those who build SCSI as modules, there's a new scsi_wait_scan module that will ensure all bus scans are finished. This patch only handles drivers which call scsi_scan_host. Fibre Channel, SAS, SATA, USB and Firewire all need additional work. Signed-off-by: NMatthew Wilcox <matthew@wil.cx> Signed-off-by: NJames Bottomley <James.Bottomley@SteelEye.com>

- Eliminate casts to/from void* - Eliminate checks for conditions that never occur. These typically fall into two classes: 1) Checking for 'dev_id == NULL', then it is never called with NULL as an argument. 2) Checking for invalid irq number, when the only caller (the system) guarantees the irq handler is called with the proper 'irq' number argument.

由 David Howells 提交于
Maintain a per-CPU global "struct pt_regs *" variable which can be used instead of passing regs around manually through all ~1800 interrupt handlers in the Linux kernel. The regs pointer is used in few places, but it potentially costs both stack space and code to pass it around. On the FRV arch, removing the regs parameter from all the genirq function results in a 20% speed up of the IRQ exit path (ie: from leaving timer_interrupt() to leaving do_IRQ()). Where appropriate, an arch may override the generic storage facility and do something different with the variable. On FRV, for instance, the address is maintained in GR28 at all times inside the kernel as part of general exception handling. Having looked over the code, it appears that the parameter may be handed down through up to twenty or so layers of functions. Consider a USB character device attached to a USB hub, attached to a USB controller that posts its interrupts through a cascaded auxiliary interrupt controller. A character device driver may want to pass regs to the sysrq handler through the input layer which adds another few layers of parameter passing. I've build this code with allyesconfig for x86_64 and i386. I've runtested the main part of the code on FRV and i386, though I can't test most of the drivers. I've also done partial conversion for powerpc and MIPS - these at least compile with minimal configurations. This will affect all archs. Mostly the changes should be relatively easy. Take do_IRQ(), store the regs pointer at the beginning, saving the old one: struct pt_regs *old_regs = set_irq_regs(regs); And put the old one back at the end: set_irq_regs(old_regs); Don't pass regs through to generic_handle_irq() or __do_IRQ(). In timer_interrupt(), this sort of change will be necessary: - update_process_times(user_mode(regs)); - profile_tick(CPU_PROFILING, regs); + update_process_times(user_mode(get_irq_regs())); + profile_tick(CPU_PROFILING); I'd like to move update_process_times()'s use of get_irq_regs() into itself, except that i386, alone of the archs, uses something other than user_mode(). Some notes on the interrupt handling in the drivers: (*) input_dev() is now gone entirely. The regs pointer is no longer stored in the input_dev struct. (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does something different depending on whether it's been supplied with a regs pointer or not. (*) Various IRQ handler function pointers have been moved to type irq_handler_t.
