The MMC layer uses the standard work queue for doing card detection.  As this
queue is shared with other crucial subsystems, the effects of a long (and
perhaps buggy) detection can cause the system to be unusable.  E.g.  the
keyboard stops working while the detection routine is running.

The solution is to add a specific mmc work queue to run the detection code in.
This is similar to how other subsystems handle detection (a full kernel
thread is the most common theme).

Some Ricoh controllers only respect a full reset when there is no card in the
slot.  As we wait for the reset to complete, we must avoid even requesting
those resets on the buggy controllers.

The cause of this problem might be an wrong assumption that the 'start'
member of resource structure for ioapic device has non-zero value if the
resources are assigned by firmware.  The 'start' member of ioapic device
seems not to be set even though the resources were actually assigned to
ioapic devices by firmware.

Not all architectures have a file named 'defconfig' (e.g.  powerpc).
However the make TAGS and make tags targets search such files for tags,
causing an error message when they don't exist.  This patch addresses the
problem by instructing xargs not to run the tags program if there are no
matching files.

- rename ____kmalloc to kmalloc_track_caller so that people have a chance
  to guess what it does just from it's name.  Add a comment describing it
  for those who don't.  Also move it after kmalloc in slab.h so people get
  less confused when they are just looking for kmalloc - move things around
  in slab.c a little to reduce the ifdef mess.

Spotted by Hugh that hugetlb page is free'ed back to global pool before
performing any TLB flush in unmap_hugepage_range().  This potentially allow
threads to abuse free-alloc race condition.

The generic tlb gather code is unsuitable to use by hugetlb, I just open
coded a page gathering list and delayed put_page until tlb flush is
performed.

Having min be a signed quantity means gcc can't turn high latency divides
into shifts.  There happen to be two such divides for GFP_ATOMIC (ie.
networking, ie.  important) allocations, one of which depends on the other.
