Linus Torvalds 95fc76c81b 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.
