[PATCH] arch/microblaze/include/asm/entry.h: Include "linux/linkage.h" to avoid compiling issue

[Chen Gang]

"entry.h" needs 'asmlinkage', and "asm/linkage.h" does not provide it.
So need include "linux/linkage.h" to use generic one instead of.

The related error (with allmodconfig under microblaze):

    CC [M]  drivers/net/ethernet/emulex/benet/be_main.o
  In file included from ./arch/microblaze/include/asm/processor.h:17:0,
