85958b465c x86: unify pgd ctor/dtor
All pagetables need fundamentally the same setup and destruction, so
just use the same code for everything.

68db065c84 x86: unify KERNEL_PGD_PTRS
Make KERNEL_PGD_PTRS common, as previously it was only being defined
for 32-bit.

There are a couple of follow-on changes from this:
 - KERNEL_PGD_PTRS was being defined in terms of USER_PGD_PTRS.  The
   definition of USER_PGD_PTRS doesn't really make much sense on x86-64,
   since it can have two different user address-space configurations.
   I renamed USER_PGD_PTRS to KERNEL_PGD_BOUNDARY, which is meaningful
   for all of 32/32, 32/64 and 64/64 process configurations.

 - USER_PTRS_PER_PGD was also defined and was being used for similar
   purposes.  Converting its users to KERNEL_PGD_BOUNDARY left it
   completely unused, and so I removed it.

934b7024f0 Fix cardbus resource allocation
Commit 884525655d ("PCI: clean up resource
alignment management") didn't set the alignment information for the
cardbus window resources, causing their subsequent allocations to fail
miserably with a message like

  yenta_cardbus 0000:15:00.0: device not available because of BAR 7 [100:1ff] collisions
  yenta_cardbus: probe of 0000:15:00.0 failed with error -16

or similar.

This fixes it and clarifies the code a bit too (we used to have to use
the insane PCI bridge alignment logic that put the alignment in the
"start" field, this makes it use the slightly easier-to-understand
size-based alignment, and allows us to set the resource start to zero
until it gets allocated).

1ec7f1ddbe [PATCH] get rid of __exit_files(), __exit_fs() and __put_fs_struct()
The only reason to have separated __...() for those was to keep them inlined

d4ce220d49 i2c-bfin-twi: Just let i2c-bfin-twi driver depends on BLACKFIN
Simply use "depends on BLACKFIN" (which is technically correct) and just
document which machines have the device.

74d362e0b3 i2c-bfin-twi: Add missing pin mux operation
Blackfin TWI controller hardware pin should be requested from GPIO port controller
Before BF54x, there is no need to do this. But as long as BF54x and BF52x
are supported by this generic driver, the missing pin mux operation should be
added.
