Subject: [PATCH 00/13] RTAS maintenance
Date: Fri, 18 Nov 2022 09:07:38 -0600	[thread overview]
Message-ID: <20221118150751.469393-1-nathanl@linux.ibm.com> (raw)

A collection of loosely-related RTAS code changes, most notably:

* Fixing misuses of rtas_token() for non-function properties.
* The stronger validation for sys_rtas() offered by the
  PPC_RTAS_FILTER config option is always enabled.
* Improved function token lookups, including efficient "reverse"
  token-to-name mappings.
* Static tracepoints for RTAS entry and exit.

Nathan Lynch (13):
  powerpc/rtas: document rtas_call()
  powerpc/rtasd: use correct OF API for event scan rate
  powerpc/rtas: avoid device tree lookups in rtas_os_term()
  powerpc/rtas: avoid scheduling in rtas_os_term()
  powerpc/pseries/eeh: use correct API for error log size
  powerpc/rtas: clean up rtas_error_log_max initialization
  powerpc/rtas: clean up includes
  powerpc/rtas: define pr_fmt and convert printk call sites
  powerpc/rtas: mandate RTAS syscall filtering
  powerpc/rtas: improve function information lookups
  powerpc/rtas: strengthen do_enter_rtas() type safety, drop inline
  powerpc/tracing: tracepoints for RTAS entry and exit
  powerpc/rtas: place tracepoints in do_enter_rtas()
