Subject: [PATCH 0/2] LoongArch: Cleanup with zero page

There is no color page and only one page for zero page, so symbol
zero_page_mask can be removed. Also like other architectures this
patch uses statically defined zero_page in bss code segment, rather
than dynamically allocated page for zero_page usage.

  LoongArch: Remove zero_page_mask symbol
  LoongArch: Use static defined zero page rather than allocated
