https://git.shady.money/linux/atom?h=v5.22018-08-13T07:54:17Zparisc: Fix and improve kernel stack unwinding2018-08-13T07:54:17ZHelge Dellerdeller@gmx.de2018-08-04T22:03:29Zurn:sha1:c8921d72e390cb6fca3fb2b0c2badfda851647eb
This patchset fixes and improves stack unwinding a lot:
1. Show backward stack traces with up to 30 callsites
2. Add callinfo to ENTRY_CFI() such that every assembler function will get an
entry in the unwind table
3. Use constants instead of numbers in call_on_stack()
4. Do not depend on CONFIG_KALLSYMS to generate backtraces.
5. Speed up backtrace generation
Make sure you have this patch to GNU as installed:
https://sourceware.org/ml/binutils/2018-07/msg00474.html
Without this patch, unwind info in the kernel is often wrong for various
functions.

This trivial patch fixes the following section warnings on PARISC:
> WARNING: vmlinux.o (.text.1): unexpected section name.
>The (.[number]+) following section name are ld generated and not expected.
> Did you forget to use "ax"/"aw" in a .S file?
> Note that for example <linux/init.h> contains
> section definitions for use in .S files.

.align applies to the current section - ie section directives come first.
Thanks to Joel Soete for catching this.
