In kernel 2.6.16, if a mounted storage device is removed, an oops happens
because ub supplies an interface device (and kobject) to the block layer,
but neglects to pin it. And apparently, the block layer expects its users
to pin device structures.

The code in ub was broken this way for years. But the bug was exposed only
by 2.6.16 when it started to call block_uevent on close, which traverses
device structures (kobjects actually).

The choose_configuration() routine contains code the determine the
device's power source, so that configurations requiring external power
can be ruled out if the device is running on bus power.  Unfortunately
it turns out that some devices have errors in their config descriptors
and other devices don't like the GET_DEVICE_STATUS request.

Since that information wasn't used for anything else, this patch (as673)
removes the code, leaving only a comment.  It fixes bugzilla entry
#6448.

This fixes a small regression in USB controller power usage for many
OHCI controllers, notably including every non-PCI version of OHCI:  on
those systems, the runtime autosuspend mechanism is no longer enabled.

The change moves to saner defaults.  All root hubs are expected to handle
remote wakeup (and hence autosuspend), although drivers for buggy silicon
may override that default.

The maximum possible bandwidth for a speedtouch modem is about 7Mbaud.
You can only get this by using isochronous urbs (enable_isoc=1) and
altsetting 3.  With the current default altsetting of 2, the modem
maxes out at about 4Mbaud.  So change the default altsetting to 3
when using isochronous urbs.  It would be nice to base the altsetting
on the detected line speed, but that's hard given the current design.

Based on analysis&patch from Robert Hentosch

Observed on a Dell PE6850 with 16GB

The problem occurs very early on, when the kernel allocates space for the
temporary memory map called bootmap. The bootmap overlaps the EBDA region.
EBDA region is not historically reserved in the e820 mapping. When the
bootmap is freed it marks the EBDA region as usable.

If you notice in setup.c there is already code to work around the EBDA
in reserve_ebda_region(), this check however occurs after the bootmap
is allocated and doesn't prevent the bootmap from using this range.

AK: I redid the original patch. Thanks also to Jan Beulich for
spotting some mistakes.

Playing with NMI watchdog on x86_64, I discovered that it didn't
do what I expected.  It always panic-ed, even when it didn't
happen from interrupt context.  This patch solves that
problem for me.  Also, in this case, do_exit() will be called
with interrupts disabled, I believe.  Would it be wise to also
call local_irq_enable() after nmi_exit()?
[Yes I added it -AK]

Currently, on x86_64, any NMI watchdog timeout will cause a panic
because the irq count will always be set to be in an interrupt
when do_exit() is called from die_nmi().  If we add nmi_exit() to
the die_nmi() call (since the nmi will never exit "normally")
it seems to solve this problem.  The following small program
can be used to trigger the NMI watchdog to reproduce this:
  main ()
  {
        iopl(3);
        for (;;) asm("cli");
  }

I noticed this when poking around in this area.

The oops_begin() function in x86_64 would only conditionally claim
the die_lock if the call is nested, but oops_end() would always
release the spinlock. This patch adds a nest count for the die lock
so that the release of the lock is only done on the final oops_end().

The patch addresses a problem with ACPI SCI interrupt entry, which gets
re-used, and the IRQ is assigned to another unrelated device.  The patch
corrects the code such that SCI IRQ is skipped and duplicate entry is
avoided.  Second issue came up with VIA chipset, the problem was caused by
original patch assigning IRQs starting 16 and up.  The VIA chipset uses
4-bit IRQ register for internal interrupt routing, and therefore cannot
handle IRQ numbers assigned to its devices.  The patch corrects this
problem by allowing PCI IRQs below 16.

It is insane to be giving lease_init() the task of freeing the lock it is
