Subject: [PATCH v8 05/12] sparc: Use the common syscall table
Date: Fri, 18 Sep 2026 21:31:12 -0300 [thread overview]
Message-ID: <20260918-tonyk-syscall_table-v8-5-0e2d60cad13e@igalia.com> (raw)
In-Reply-To: <20260918-tonyk-syscall_table-v8-0-0e2d60cad13e@igalia.com>
Remove some of the duplicated code by using the common syscall number
table.
The generated files are not exactly the same as before, but they have no
functional changes:
- syscall_table_32.h would generated lines like the following
__SYSCALL_WITH_COMPAT(422, sys_futex, sys_futex), which is equivalent to
__SYSCALL(422, sys_futex)
