Actually all those checks should go away ...

This patch implements the "USB Gadget" API using the
"Goku-S" (TC86C001) full speed usb device controller.

It's passed testing with Gadget Zero, g_ether (full
CDC Ethernet support), gadgetfs, and most interestingly
Alan Stern's "File Storage Gadget" (FSG, talking to
Linux or Windows as a usb-storage device) to give the
halt processing a good workout.  Control-OUT works.
Tested mostly on x86, with reported success on MIPS.

As well as being directly useful with that hardware,
I think this is small and simple enough to be useful
as an example of how to write a USB controller driver.
(There will be many more controller drivers than gadget
drivers, I suspect ...)

Please merge this to the next 2.6 release that takes
new drivers.  Corresponding updates for kbuild and the
various gadget drivers will be coming (not in a flood).

Thanks to Stefan Verkoyen <stefan.verkoyen@quesd.com> for the information.

Fix for oops on rmmod caused by *_remove() function marked as __devinit
(and thus discarded after module initialization - if CONFIG_MODULES=y
and CONFIG_HOTPLUG is not set).
This patch changes __devinit to __devexit and adds __devexit_p() where
pointer to such function is used.

The only exception is au1000, where au1000_remove() is called from
cleanup_au1000() function - __devinit is jest removed there.

It was also removed in 2.4.23.

Use rq->cmd[0] instead of rq->flags for storing special request flags.

Per Jens' suggestion.  Tested by Stef van der Made <svdmade@planet.nl>.

Revert wrong changes introduced in 2.4.21.

The MSI port to x86-64 added an interrupt routing bug that makes the
kernel not boot anymore on some machines.

Fix that.

sometimes nanoseconds are used, sometimes microseconds, sometimes even something else.

On ARM, it is possible to configure the desired cache policy in
the page tables.  Unfortunately, we haven't been updating the
protection_map nor PAGE_KERNEL, so this option doesn't change
the behaviour of the majority of mappings.  This cset corrects
this oversight.

I have a PROLiNK 1456VH internal Rockwell-based ISA PnP K56flex fax modem
whose EISA ID seems not to be known to 8250_pnp.c. The ID is AEI0250 as
reported in /sys/devices/pnp1/01:01/01:01.00/id and adding this into the
pnp_dev_table[] allows the device to be found and enabled properly by the
8250 serial driver.

From Daniel Tram Lux: under extreme irq load on an underpowered CPU,
the timeout loop may not make any progress, and decide that a timeout
occurred before it has actually tested the status register.

The minimal fix for now is to just have a final test _after_ the timeout
to remove the problem. The real fix would likely be to not have irqs
enabled between reading the status and the timeout. 

The resource handling left in autoconfig() is plainly wrong, since
we've already claimed the necessary resources prior to calling
autoconfig().  Therefore, we remove the superfluous code from
autoconfig().

This patch adds the PnP ID for the E-Tech CyberBULLET PC56RVP.

The memset for C stepping K8 was broken. This broke mainly CONFIG_SLAB_DEBUG
because memset(...., 0, ...) still worked correctly.

Thanks to Manfred Spraul for giving me the right cue.

At least one of them is critical. It fixes an path in the IOMMU that
I broke with the ealier "fullflush" workaround.

 - Check for ~/bin/installkernel like i386 (M. Bligh) 
 - Implement 32bit RTC_IRQ_SET correctly (Lutz Vieweg)
 - Disable some useless printks in 32bit emulation
 - Warning fixes for mixed C99 style declarations/statements.
 - Sync lAPIC power management with i386
 - Use topology sysfs like i386
 - Fix some serious bugs in the MCE handler. ECC should
   be decoded correctly now.
 - Add oops=panic option to panic on Oopses.
 - Fix hackish code in head.S
 - Add missing options in IOMMU
 - Fix _syscall6 (Olaf Hering)
 - Remove broken ACPI locking code. Port IA64 C version.
 - Make safe_smp_processor_id() more reliable
 - Read HPET in vsyscall code
 - Add workaround for BIOS that corrupt 64bit registers in HLT
 - Fix unaligned access in bitops.h
 - Remove broken ntp drift correction code for now
 - i386 merge in SCI setup
 - Fix wrong offset in callin.h (Jim Houston)
 - Minor comment fixes

 - do not allocate firmware buffer if firmware is compiled into the
   driver.  Saves 220KB vmem (Andreas Oberritter)

 - Alter hotplug firmware naming to fit in with dvb standard.
 - Use the hotplug firmware loader for 2.6 kernels instead of compiling
   the firmware into the module. 
 - Integrate frontend into ttusb_dec module and remove pseudo-i2c bits,
   move ttusb_dec header into source file.
 - Rudimentary section filter support (enough for scan).
