TIF_SECCOMP is removed from x86's thread_info.h about kernelsu

[hmtheboy154]

x86/x86_64 use syscall_work instead

I replace TIF_SECCOMP with SYSCALL_WORK_SECCOMP and it works, so we need make a condition for this

It seems that this is not a problem of x86/x86_64, kernel above 5.11 migrate the TIF_flags to syscall_work flags: https://www.mail-archive.com/[email protected]/msg2382193.html

[hmtheboy154]

but arm/arm64 still got TIF_flags though

[tiann]

Does your kernel have CONFIG_GENERIC_ENTRY enabled?

[hmtheboy154]

yes

[hmtheboy154]

oh we can make a condition using CONFIG_GENERIC_ENTRY then

[tiann]

I think it is this config that makes the difference

[hmtheboy154]

fixed
