Thanks for your update!
When I compiled the kernel I got below warnings.
<stdin>:696:2: warning: #warning syscall nfsservctl not implemented [-Wcpp]
<stdin>:1335:2: warning: #warning syscall rseq not implemented [-Wcpp]
I added an IGNORE entry nfsservctl in script/checksyscalls.sh because this
syscall is gone. But we definitely have to keep rseq entry on parisc
architecture.
I can ignore this patch currently as your patch not yet tested.
FYI, I have merged the system call table files based on our previous
discussions.
Please comment on that.
I would appreciate if you can perform a boot test without this patch
on the actual
platform.
