Re: [PATCH v5 12/13] alpha: Remove alpha_ prefix from custom syscall entries

[sashiko-bot@kernel.org]

Thank you for your contribution! Sashiko AI review found 1 potential issue(s) to consider:
- [Low] The `clone3` syscall entry in the syscall table specifies `__clone3`, which does not match the actual assembly entry point `__sys_clone3` generated by the `fork_like` macro, causing a linkage failure.

alpha: Remove alpha_ prefix from custom syscall entries

This commit removes the alpha_ prefix from custom architecture-specific syscall
entry points and renames them to use the standard __sys_ prefix. This aligns
alpha with other architectures to make it easier to join the syscall tables.

[Severity: Low]
Will this cause a linkage failure during the kernel build for the alpha
architecture due to an undefined symbol?

Because the fork_like macro in entry.S now prefixes entry points with
__sys_, the generated entry function for clone3 is __sys_clone3. Does this
table entry need to be updated to __sys_clone3 instead of __clone3 so that
it correctly resolves the assembly entry point?
