05e9ebbefb [SCSI] megaraid_sas: intercept cmd timeout and throttle io
eh_timed_out call back (megasas_reset_timer) is used to throttle io
to the adapter when it is called the first time for a scmd.
The MEGASAS_FW_BUSY flag is set and can_queue reduced to 16.
The can_queue is restored from completion routine in following
two conditions : 5 seconds has elapsed and
the # of outstanding cmds in FW is < 17.

e8edc6e03a Detach sched.h from mm.h
First thing mm.h does is including sched.h solely for can_do_mlock() inline
function which has "current" dereference inside. By dealing with can_do_mlock()
mm.h can be detached from sched.h which is good. See below, why.

This patch
a) removes unconditional inclusion of sched.h from mm.h
b) makes can_do_mlock() normal function in mm/mlock.c
c) exports can_do_mlock() to not break compilation
d) adds sched.h inclusions back to files that were getting it indirectly.
e) adds less bloated headers to some files (asm/signal.h, jiffies.h) that were
   getting them indirectly

Net result is:
a) mm.h users would get less code to open, read, preprocess, parse, ... if
   they don't need sched.h
b) sched.h stops being dependency for significant number of files:
   on x86_64 allmodconfig touching sched.h results in recompile of 4083 files,
   after patch it's only 3744 (-8.3%).

	all arm defconfigs, all mips defconfigs, all powerpc defconfigs,
	alpha alpha-up

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.

f5ebbeb57e [SCSI] megaraid: Use the proper type to hold the irq number.
When testing on a Unisys machine it was discovered that the megaraid driver
would not initialize as it was requesting irq 162 instead of irq 1442 it
was assigned.  The problem was the irq number had been truncated by being
stored in an unsigned char.

This patches fixes that problem and the driver now appears to work.

The ioctl interface appears fundamentally broken as it exports the irq
number to user space in an unsigned char.

Without this patch, the driver used to blindly claim 64-bit DMA

e5b3a65fd7 [SCSI] megaraid_sas: fix extended timeout handling
Replace the eh_timed_out method usage with setting sdev->timeout in
slave_configure.  Also only use the extended timeout for raid volumes,
physical devices shouldn't need it.

147aab6aa2 [SCSI] megaraid_sas: fix physical disk handling
This patch hides the devices completely from the midlayer instead.
It requires the patch to handle the slave_configure failure I posted
earlier.

1341c93922 [SCSI] megaraid_sas: new template defined to represent each type of controllers
This patch defines a new template to represent each type of
controllers (identified by the processor used). The template has
members that is set with appropriate values during driver
initialisation. This change is done to support new controllers with
minimal change to existing code. In future, for a new controller
support, a template will be declared and its members initialised
appropriately.
