  1. lm32: Slightly optimize the syscall handling 

    We can get rid of the null-pointer check in the syscall handler if we make sure
that every syscall table entry is initialized.

  2. lib: Add a generic sys_call_table 

    Most of the new architectures use identical sys call tables definitions. This
patch adds a generic sys call table implementation which can be used by these
architectures.

  4. lm32: Speedup clearing the bbs section a bit 

    We currently do two branch, one add and one store instruction per word in the
bss section. Change this to one branch, one add and 8 stores per 8 words.

  6. asm-generic/mmu.h: Remove unused vmlist field from mm_context_t 

    Nothing is using the vmlist field in mm_context_t anymore. It has been removed
from the non-generic versions over 3 years ago 8feae13 ("NOMMU: Make VMAs per
MM as for MMU-mode linux").

  7. asm-generic/mmu.h: Add support for FDPIC 

    No-MMU architectures often have support for FDPIC binaries. FDPIC support
requires two additional fields in the mm_context_t struct. This patch adds these
fields to the generic mm_context_t definition if support for FDPIC binaries is
enabled. This allows to use the generic mmu.h for a few more architectures.

  9. lm32: Use generic tlb.h 

    We do have some custom definitions in our tlb.h, but those are all for
defines/functions which are only used in the MMU case.
