From: Guo Ren <guoren@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: https://lore.kernel.org/linux-riscv/20231219111701.1886903-1-guoren@kernel.org/
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
