* machine/stdarg.h -> sys/stdarg.hBrooks Davis2025-06-111-1/+1
| | | | | | | | | | | | | Switch to using sys/stdarg.h for va_list type and va_* builtins. Make an attempt to insert the include in a sensible place. Where style(9) was followed this is easy, where it was ignored, aim for the first block of sys/*.h headers and don't get too fussy or try to fix other style bugs.

* [PowerPC64LE] Fix RTAS LE calls in pseries.Brandon Bergren2020-09-231-6/+7
| | | | | | | | | | | Similar to OPAL calls, switch to big endian to do calls to RTAS. (Missed this one when I was doing the bulk commit of PowerPC64LE support.) Sponsored by: Tag1 Consulting, Inc. Notes: svn path=/head/; revision=366063

* sys/powerpc: further adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-271-0/+2
| | | | | | | | | | | | | | | Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. Notes: svn path=/head/; revision=326261

* Make RTAS calls, which call setfault() to recover from machine checks,Nathan Whitehorn2013-11-271-2/+3
| | | | | | | | | | | preserve any existing fault buffer. RTAS calls are meant to be safe from interrupt context (and are indeed used there to implement the xics PIC drvier). Without this, calling into RTAS in interrupt context would have the effect of clearing any existing onfault state of the interrupted thread, potentially leading to a panic.
