  powerpc/32: Fix overread/overwrite of thread_struct via ptrace (2022-06-09 23:32:56 +1000)

- ------------------------------------------------------------------
powerpc fixes for 5.19 #2

 - On 32-bit fix overread/overwrite of thread_struct via ptrace PEEK/POKE.

 - Fix softirqs not switching to the softirq stack since we moved irq_exit().

 - Force thread size increase when KASAN is enabled to avoid stack overflows.

 - On Book3s 64 mark more code as not to be instrumented by KASAN to avoid crashes.

 - Exempt __get_wchan() from KASAN checking, as it's inherently racy.

 - Fix a recently introduced crash in the papr_scm driver in some configurations.

 - Remove include of <generated/compile.h> which is forbidden.

Thanks to: Ariel Miculas, Chen Jingwen, Christophe Leroy, Erhard Furtner, He Ying, Kees
Cook, Masahiro Yamada, Nageswara R Sastry, Paul Mackerras, Sachin Sant, Vaibhav Jain,
Wanming Hu.
