Subject: [RFC PATCH 0/7] x86/entry: Create a home for the x86 entry code in arch/x86/entry/
So the x86 syscall/irq/etc. entry code is scattered in
over 40 files all over the x86 architecture, making it
hard to get a good overview of the code and its current
status.
Move all the files to arch/x86/entry/.
This first step is as-is, no file names were changed - but the next
step will be to organize things in a bit more maintainable fashion.
If there are no fundamental objections then I'll commit this to
tip:x86/asm. (I've drained most of the pending patches to these
files - but porting them should be easy in any case.)
Thanks,
Ingo
