linux-next: build failure after merge of the vfs tree

[Stephen Rothwell]

Hi Al,

After merging the vfs tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:

net/sunrpc/auth_gss/svcauth_gss.c: In function 'write_gssp':
net/sunrpc/auth_gss/svcauth_gss.c:1329:9: error: implicit declaration of function 'PDE' [-Werror=implicit-function-declaration]
net/sunrpc/auth_gss/svcauth_gss.c:1329:53: error: invalid type argument of '->' (have 'int')
net/sunrpc/auth_gss/svcauth_gss.c: In function 'read_gssp':
net/sunrpc/auth_gss/svcauth_gss.c:1357:53: error: invalid type argument of '->' (have 'int')

Caused by commit 030d794bf498 ("SUNRPC: Use gssproxy upcall for server
RPCGSS authentication") from the nfsd tree interacting with commit
c3f2cb25be4f ("proc: Make the PROC_I() and PDE() macros internal to
procfs") from the vfs tree.

I applied the following merge fix patch (there may be a better way).
