[parisc-linux] Type sizes

[Matthew Wilcox]

What was the reasoning behind:

/* Note these change from narrow to wide kernels */
#ifdef __LP64__
typedef unsigned long           __kernel_size_t;
typedef long                    __kernel_ssize_t;
typedef long                    __kernel_ptrdiff_t;
typedef long                    __kernel_time_t;
#else
typedef unsigned int            __kernel_size_t;
typedef int                     __kernel_ssize_t;
typedef int                     __kernel_ptrdiff_t;
typedef int                     __kernel_time_t;
#endif

in <asm/posix_types.h> ?

on a 32-bit kernel, sizeof(long) == sizeof(int), so why can't we just use
the first set of typedefs?
