OpenRISC includes 3 TLS addressing models. Local Dynamic optimizations
are not done in the linker and therefore use the same code sequences as
Global Dynamic.

We don't use '*' at the start of second and subsequent lines of comments.
(It seems unfortunate for a new port to default to executable stacks, but
it looks like this is indeed what the Linux kernel port to OpenRISC does,
given the lack of an override of the default VM_DATA_DEFAULT_FLAGS and
VM_STACK_DEFAULT_FLAGS.)

OK, I went through the patch's and made sure I have this on all .c .h and .S
files.

OK, I went through the patch and tried to sort all of these occurances out.
Also there were a few where we didn't have two spaces after period ".". Also, a
few other similar issues.

Yes.
Thanks for reviewing.

OpenRISC support hard float but I will like to submit that after glibc
soft float goes upstream. The hard float support depends on adding user
access to the FPCSR, which is not supported by the kernel yet.

Missing one-line description at start of file.
The constants you're defining here seem to be specific to hard float, but
they're defined unconditionally. Is this because you use the same ABI for
hard float and soft float (which is generally the case when such hard
float constants might be defined for soft float as well - a soft float
compilation could be using a hard float libc that supports those
constants)?

Macros need to be properly surrounded by parentheses so they always group
as a single operand in any expression.

Likewise in sfp-machine.h.

OK Added for v3.

Yes, it's the same ABI. I have patches for hard float but am not submitting
until the Linux side is sorted out as mentioned in the comment. It seems
delcairing these conditionally was normal, hence I didn't mention anything about
it.
I didn't think as far as allowing for shared libc usage between soft/float
float, but I think that would work.

This file seems to be missing a definition of __NR_process_mrelease. Make
sure you regenerate it with Linux 5.15, the current version used for
syscall lists in glibc.

Right, I will update. I have been trying to play catch up with upstream, I
didn't update this yet.

Maybe we should refactor to make this the default for newer ports and make
old ports to redefine it.

I think it would be better to make it the default implementation.
Unfortunately it might result in worse code, but I think the assumption
on auto-generation syscall that varargs are always passed in register
also fragile.

This is replicated for all architectures and it can be replaced with a
gen-as-const-headers file. I will fix it upstream, so there won't be
the need to add this new header.

So the generic Linux interface only misses the STAT64_IS_KERNEL_STAT64, right?
I think we can add it and thus or1k just need to ajust __STATFS_MATCHES_STATFS64.

MMAP2_PAGE_UNIT set to -1 means the architecture supports multiple
page size, but from the comment my understanding it only support 8k.
If it where the case it would be simpler to just set MMAP2_PAGE_UNIT
to 8192ULL.
As a side note, maybe arc should do it as well.

As for ioctl.c, I also think this should the set as the default implementation.
It would allows us to remove the hppa version as well.
(maybe also add a INTERNAL_SYSCALL_CALL_NCS, to get rid of the requirement to
pass the number of arguments).

This is another thing I have in my backlog to cleanup: I think we also should
move it to default implementation. The architectures that uses non standard
call procedure already implement it with assembly routines.

I think we might need to update update-syscall-lists.py to *not* emit
no emit 32-bit time syscalls if the architecture only exports 64-bit
interfaces.

It makes sense, it may be easier to do once/if the port it merged.
I am often playing catch up as upstream moves forward.

I see you have just posted a generic ioctl implementation that does this. I
will rebase and use/test that.

This seems to be a lot more recent than when OpenRISC support was actually
added to the Linux kernel, and also more recent than when 64-bit time
support was added for 32-bit architectures (which may be a convenient
minimum kernel for some new 32-bit architectures for that reason).
Requiring a newer kernel like that is certainly fine if convenient for the
port, but I think the choice of minimum kernel version, and the reasons
for it, deserve mention at least in the commit message and the NEWS file
entry.

OK, during the v1 review you mentioned:
You'll probably need a newer minimum kernel when requiring 64-bit time
support, until all the fallback for 64-bit time on 32-bit kernels without
the 64-bit-time syscalls is implemented.
I really just chose the version I was working on at the time. I just looked
back on it, this version 5.10 is good because. 1. it is a long term support
version. 2. in 5.8 I fixed a kernel bug which caused clone/fork to not work
with TLS.
I will upate the commit/news.
