Subject: [PATCH v3 0/8] Enable pt_regs based syscalls for x86-32 native
Date: Thu, 27 Feb 2020 08:28:18 -0500 [thread overview]
Message-ID: <20200227132826.195669-1-brgerst@gmail.com> (raw)
This patch series cleans up the x86 syscall wrapper code and converts
the 32-bit native kernel over to pt_regs based syscalls. This makes
the 32-bit syscall interface consistent with 64-bit, and a bit more
effecient by not blindly pushing all 6 potential arguments onto the
stack.
Changes since v2:
- Moved adding the [compat_]sys_ prefix to the ABI-level macros
Changes since v1:
- Split patch 1 into multiple patches
- Updated comments and patch notes to clarify changes

x86, syscalls: Refactor SYSCALL_DEFINEx macros
x86, syscalls: Refactor SYSCALL_DEFINE0 macros
x86, syscalls: Refactor COND_SYSCALL macros
x86, syscalls: Refactor SYS_NI macros
x86: Move 32-bit compat syscalls to common location
x86-32: Enable syscall wrappers
x86-64: Use syscall wrappers for x32_rt_sigreturn
x86: Drop asmlinkage from syscalls
