include/linux/generic-radix-tree.h: replace kernel.h with the necessary inclusions
...
When kernel.h is used in the headers it adds a lot into dependency hell,
especially when there are circular dependencies are involved.
Replace kernel.h inclusion with the list of what is really being used.
[akpm@linux-foundation.org: include math.h for round_up()]

lib/generic-radix-tree.c: remove unneeded __rcu
...
struct __genradix is defined as having its member 'root'
annotated as __rcu. But in the corresponding API RCU is not used.
Sparse reports this type mismatch as:
lib/generic-radix-tree.c:56:35: warning: incorrect type in initializer (different address spaces)
lib/generic-radix-tree.c:56:35: expected struct genradix_root *r
lib/generic-radix-tree.c:56:35: got struct genradix_root [noderef] <asn:4> *__val
with 6 other ones.
So, correct root's type by removing this unneeded __rcu.

include/linux/generic-radix-tree.h: fix kerneldoc comment
...
The DOC comment block section in include/linux/generic-radix-tree.h
contained a spurious colon, causing this warning in the documentation
build:
include/linux/generic-radix-tree.h:1: warning: no structured comments found
Remove the colon and make the docs build happy.

generic radix trees
...
Very simple radix tree implementation that supports storing arbitrary
size entries, up to PAGE_SIZE - upcoming patches will convert existing
flex_array users to genradixes. The new genradix code has a much
simpler API and implementation, and doesn't have a hard limit on the
number of elements like flex_array does.
