net/chelsio/libcxgb: Add __percpu annotations to libcxgb_ppm.c
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: expected void const [noderef] __percpu *__vpp_verify
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.
