Chad Dupuis e05fe29248 qla2xxx: Honor FCP_RSP retry delay timer field.
Parse the retry delay timer field from the FCP response data and if:

- It is not zero
- The SCSI status is busy or queue full

return SCSI_MLQUEUE_TARGET_BUSY for the number of milliseconds specified
in the retry delay timer field.

gurinder.shergill@hp.com 364398324c [SCSI] qla2xxx: Fix for locking issue between driver ISR and mailbox routines
The driver uses ha->mbx_cmd_flags variable to pass information between
its ISR and mailbox routines, however, it does so without the protection of
any locks.  Under certain conditions, this can lead to multiple mailbox
command completions being signaled, which, in turn, leads to a false
mailbox timeout error for the subsequently issued mailbox command.

The issue occurs frequently but intermittenly with the Qlogic 8GFC mezz
card during card initialization, resulting in card initialization failure.

Arun Easi e02587d777 [SCSI] qla2xxx: T10 DIF - Fix incorrect error reporting.
This fix:
    - Disables app tag peeking; correct tag check will be added when the
      SCSI API is available.
    - Always derive ref_tag from scsi_get_lba()
    - Removes incorrect swap of FCP_LUN in FCP_CMND
    - Moves app-tag error check before ref-tag check. The reason being,
      currently there is no interface in SCSI to retrieve the app-tag
      for protection I/Os, so driver puts zero for app-tag in the
      firmware interface, but requests not to validate it, but when a
      ref-tag error is detected by firmware, it would put
      expected/actual tags for all the protection tags (guard/app/ref).
      As driver checks for app tag error first, a ref-tag error is
      incorrectly flagged as app-tag error.
    - Convert HBA specific checks to capability based.

Which shows that lockdep is detecting the driver's
interrupt-handler is run in both process and interrupt context
with irqs-enabled in the former case.

During init-time and error-recovery (after a RISC reset), the
driver disables interrupts and 'polls' for completions by calling
qla2x00_poll():

	static inline void
	qla2x00_poll(scsi_qla_host_t *ha)
	{
		ha->isp_ops->intr_handler(0, ha);
	}

which in-turn calls the ISP registered interrupt handler.  This
patch corrects it by disabling local interrupts during polling.

David Howells 7d12e780e0 IRQ: Maintain regs pointer globally rather than passing to IRQ handlers
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.

Linus Torvalds 1da177e4c3 Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
