I have noticed one relatively big (but easily fixable) commit
structure problem in this tree.
All of the commits have these tags:
Reviewed-by: Stephen Neuendorffer <stephen.neuendorffer@...inx.com>
Acked-by: John Linn <john.linn@...inx.com>
Acked-by: John Williams<john.williams@...alogix.com>
I think this is the result of an misunderstanding of how to use the
tags properly. Those should all be Signed-off-by tags (with the
permission, authorization and full knowledge of each person along
the signoff chain).
Acked-by does not carry the same legal weight as Signed-off-by. See
Documentation/SubmittingPatches and in particular for details:
Developer's Certificate of Origin 1.1
I've also done a (quick) license scan and there's this one file i
found:
arch/microblaze/kernel/hw_exception_handler.S

That is an all rights reserved copyrighted file, and i'm not sure
the above constitutes a GPLv2 compatible license. It would be less
ambigious to add what you do in the other places instead, something
like:

A quick look at the technical details suggest that arch/microblaze
certainly looks like a nicely done architecture.
It is spartan but uses modern core kernel facilities for everything:
genirq, clockevents, generic-time, etc.
Missing bits (you might want to look into this in the future) are
various (optional) bits of instrumentation:
- irqflags-tracking (needed for lockdep)
- stacktrace support (needed for lockdep)
- function tracer bits
- latencytop support (I suspect you could flip on
HAVE_LATENCYTOP_SUPPORT right now as it needs no real arch code)
Etc. All of these are optional and can be added later.
There's a few obsolete comments with x86isms and old-Linux-isms in
them:
.long sys_ni_syscall /* old sys_vm86old */
.long sys_ni_syscall /* modify_ldt */
.long sys_ni_syscall /* was fork */
.long sys_ni_syscall /* old break syscall holder */
.long sys_ni_syscall /* old stat */
You could have compacted your syscall table eliminating these but i
guess you started from an existing experimental codebase and the ABI
stuck with you, right? It's not an issue.
And i guess along the way you want to remove this from your
libraries:
.long sys_ipc
... as this is a really ancient hack of a syscall. 64-bit x86 does
not have the syscall anymore. No big deal though.
Anyway, all in one it is nice work!
