8eb891fc80 Revert "USB: EHCI cpufreq fix"
This reverts commit 196705c9bb.  It was
reported to cause a regression by Daniel Exner, and Arjan van de Ven
points out that we actually already have infrastructure in place for
setting limits on acceptable DMA latency that would be the much more
correct fix for the problem with some Broadcom EHCI controllers.

Fixed up trivial conflicts due to the changes to support big-endian host
controller descriptors in drivers/usb/host/{ehci-sched.c,ehci.h}.

a947522697 USB: "sparse" cleanups for usb gadgets
This removes complaints about the gadget stack which are generated by
the currrent "sparse":  it doesn't like the fact that zero is the null
pointer.  (Last I checked, C guarantees that's correct ...)

bc71e479cd usb-serial: Fix edgeport regression on non-EPiC devices
Fix serious regression on non-EPiC edgeport usb-serial devices. Baud
rate and MCR/LCR registers are not being written on these models due
to apparent copy-n-paste errors introduced with EPiC support.

1060bce7b7 USB: more pxa2xx_udc dead code removal
Remove some more dead code from the pxa2xx_udc driver:  support
for a no-longer-undocumented hardware "test mode".  Newer chips
made this the default, evidently as the best workaround for deep
silicon bugs.  The interest was that this seemed to be the only
way to kick in the (documented!) double buffering capability.

a12b8db020 USB: fix scatterlist PIO case (IOMMU)
Update the scatterlist logic so that PIO options are also disabled
when an IOMMU may have coalesced pages during dma_map_sg() ... it's
not just HIGHMEM that can make trouble supporting both PIO and DMA
based host controller drivers.

There also seems to be a cross-arch issue here, with 64bit powerpc
not using an IOMMU define ... and its IOMMU_VMERGE config can always
be overridden on the kernel command line.  So this is better, but
still imperfect.

Coverity is right. The check for NULL is wrongly done and the error
return is lost.

20c2df83d2 mm: Remove slab destructors from kmem_cache_create().
Slab destructors were no longer supported after Christoph's
c59def9f22 change. They've been
BUGs for both slab and slub, and slob never supported them
either.

This rips out support for the dtor pointer from kmem_cache_create()
completely and fixes up every single callsite in the kernel (there were
about 224, not including the slab allocator definitions themselves,
or the documentation references).
