Compiling libcxgb_ppm.c results in several sparse warnings:
libcxgb_ppm.c:368:15: warning: incorrect type in assignment (different address spaces)
libcxgb_ppm.c:368:15: expected struct cxgbi_ppm_pool *pools
libcxgb_ppm.c:368:15: got void [noderef] __percpu *_res
libcxgb_ppm.c:374:48: warning: incorrect type in initializer (different address spaces)

libcxgb_ppm.c:374:48: got struct cxgbi_ppm_pool *
libcxgb_ppm.c:484:19: warning: incorrect type in assignment (different address spaces)
libcxgb_ppm.c:484:19: expected struct cxgbi_ppm_pool [noderef] __percpu *pool
libcxgb_ppm.c:484:19: got struct cxgbi_ppm_pool *[assigned] pool
libcxgb_ppm.c:511:21: warning: incorrect type in argument 1 (different address spaces)
libcxgb_ppm.c:511:21: expected void [noderef] __percpu *__pdata
libcxgb_ppm.c:511:21: got struct cxgbi_ppm_pool *[assigned] pool
Add __percpu annotation to *pools and *pool percpu pointers and to
ppm_alloc_cpu_pool() function that returns percpu pointer to fix
these warnings.
Compile tested only, but there is no difference in the resulting object file.

BITS_TO_LONGS() uses DIV_ROUND_UP() because of
this ppmax value can be greater than available
per cpu page pods.
This patch removes BITS_TO_LONGS() to fix this
issue.

Export cxgbi_ppm_release() to release
ppod manager and cxgbi_tagmask_set() to
set tag mask, they are used by cxgb3i, cxgb4i
and cxgbit.

Add common library module(libcxgb.ko) for
Chelsio drivers to remove duplicate code.
Code for iSCSI DDP Page Pod Manager is moved
from cxgb4.ko to libcxgb.ko. Earlier only cxgbit.ko
was using this code, now cxgb3i and cxgb4i will
also use common Page Pod manager code.
In future this module will have common connection
management and hardware specific code that can be
shared by multiple Chelsio drivers.
