Subject: simplify numerous param.h's by including <asm-generic/param.h>?

  a brief perusal of the numerous param.h files under
arch/<arch>/include/asm shows that most of them could be replaced with
a simple

  #include <asm-generic/param.h>

as is done by, for example, the microblaze param.h file.  the only
noticeable difference in those files is the value of EXEC_PAGESIZE,
which is already conditionally set in the generic version:

  #ifndef EXEC_PAGESIZE
  #define EXEC_PAGESIZE   4096
  #endif

so, at worst, a param.h file could be replaced by:

  #define EXEC_PAGESIZE <whatever>
  #include <asm-generic/param.h>

rather than duplicating the same content over and over.  (i did this
sort of centralization once upon a time with the ioctl.h file.)

  worth doing?  not worth doing?
