Subject: [PATCH] s390: fix build error for sys_call_table_emu
Date: Thu, 18 Jun 2020 19:03:20 +0800 [thread overview]
Message-ID: <20200618110320.104013-1-nixiaoming@huawei.com> (raw)
Build error on s390:
arch/s390/kernel/entry.o: in function `sys_call_table_emu':
>> (.rodata+0x1288): undefined reference to `__s390_'
In commit ("All arch: remove system call sys_sysctl")
148 common fdatasync sys_fdatasync sys_fdatasync
-149 common _sysctl sys_sysctl compat_sys_sysctl
+149 common _sysctl sys_ni_syscall
150 common mlock sys_mlock sys_mlock
After the patch is integrated, there is a format error in the generated
arch/s390/include/generated/asm/syscall_table.h:
SYSCALL(sys_fdatasync, sys_fdatasync)
SYSCALL(sys_ni_syscall,) /* cause build error */
SYSCALL(sys_mlock,sys_mlock)
There are holes in the system call number in
arch/s390/kernel/syscalls/syscall.tbl. When generating syscall_table.h,
these hole numbers will be automatically filled with "NI_SYSCALL".
Therefore, delete the number 149 to fix the current compilation failure.
Similarly, modify tools/perf/arch/s390/entry/syscalls/syscall.tbl.
Fixes: ("All arch: remove system call sys_sysctl")
