[PATCH V2 0/4] riscv: mm: Fixup & Optimize COMPAT code

[guoren at kernel.org]

From: Guo Ren <guoren at linux.alibaba.com>

When the task is in COMPAT mode, the TASK_SIZE should be 2GB, so
STACK_TOP_MAX and arch_get_mmap_end must be limited to 2 GB. This series
fixes the problem made by commit: add2cc6b6515 ("RISC-V: mm: Restrict
address space for sv39,sv48,sv57") and optimizes the related coding
convention of TASK_SIZE.

Changelog:
v2:
 - Separate rename from fixup
 - Add STACK_TOP_MAX fixup for compat
 - Add Cleanup & rename patches

v1:

Guo Ren (4):
  riscv: mm: Fixup compat mode boot failure
  riscv: mm: Fixup compat arch_get_mmap_end
  riscv: mm: Remove unused TASK_SIZE_MIN
  riscv: mm: Optimize TASK_SIZE definition
