Subject: [PATCH V2 0/4] riscv: mm: Fixup & Optimize COMPAT code
From: Guo Ren <guoren@...ux.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
