You can't add the rseq syscall for parisc yet. It needs additional code in the kernel for parisc which hasn't been tested yet. See my initial untested patch at https://patchwork.kernel.org/patch/10495209/
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.
