2021-07-01kernel.h: split out panic and oops helpersAndy Shevchenko1-0/+1
kernel.h is being used as a dump for all kinds of stuff for a long time. Here is the attempt to start cleaning it up by splitting out panic and oops helpers. There are several purposes of doing this: - dropping dependency in bug.h - dropping a loop by moving out panic_notifier.h - unload kernel.h from something which has its own domain At the same time convert users tree-wide to use new headers, although for the time being include new header back to kernel.h to avoid twisted indirected includes for existing users.

2018-09-06xtensa: ISS: don't allocate memory in platform_setupMax Filippov1-10/+15
Memory allocator is not initialized at that point yet, use static array instead. Cc: stable@vger.kernel.org Signed-off-by: Max Filippov <jcmvbkbc@gmail.com>
2017-03-13xtensa: ISS: update kernel command line in platform_setupMax Filippov1-0/+21
Move platform_setup call higher in initialization sequence so that it could change kernel command line. Check command line passed to simulator in ISS platform_stup and update kernel command line if there's anything. Signed-off-by: Max Filippov <jcmvbkbc@gmail.com>

2016-09-12xtensa: extract common CPU reset code into separate functionMax Filippov1-19/+1

2015-11-02xtensa: fixes for configs without loop optionMax Filippov1-0/+2
Build-time fixes: - make lbeg/lend/lcount save/restore conditional on kernel entry; - don't clear lcount in platform_restart functions unconditionally. Run-time fixes: - use correct end of range register in __endla paired with __loopt, not the unused temporary register. This fixes .bss zero-initialization. Update comments in asmmacro.h; - don't clobber a10 in the usercopy that leads to access to unmapped memory. Cc: <stable@vger.kernel.org> Signed-off-by: Max Filippov <jcmvbkbc@gmail.com>
