On 32 bit, size_t is "unsigned int", not "unsigned long", causing the
following warning when comparing with PAGE_SIZE, which is always "unsigned
long":
fs/cifs/file.c: In function ‘cifs_readdata_to_iov’:
fs/cifs/file.c:2757: warning: comparison of distinct pointer types lacks a cast
Introduced by commit 7f25bba819a38ab7310024a9350655f374707e20
("cifs_iovec_read: keep iov_iter between the calls of
cifs_readdata_to_iov()"), which changed the signedness of "remaining"
and the code from min_t() to min().

PAGE_SIZE should really be size_t, but that would require lots of changes
all over the place.
