[patch part-III V2 00/23] x86/entry: Consolidation - Part III (simple exceptions)

From: Thomas Gleixner
Date: Sun Mar 08 2020 - 19:24:25 EST


Hi!

This is the second version of the entry consolidation work part III
covering simple exceptions. V1 can be found here:

https://lore.kernel.org/r/20200225221606.511535280@xxxxxxxxxxxxx

It applies on top of part II which is available here

https://lore.kernel.org/r/20200308222359.370649591@xxxxxxxxxxxxx

and is also available from git (including part II):

git://git.kernel.org/pub/scm/linux/kernel/git/tglx/devel entry-v2-part3

The changes vs. V1:

- Remove #BP (int3) conversion as this needs extra care vs. kprobes (Peter)

- Fixup the FOOF bug do_invalid_op() call in fault.c

- Address the few review comments (mostly changelog and comment improvements)

- Picked up Reviewed-by and Acked-by tags

Thanks,

tglx
