| |
Hi!
This is the forth batch of a 73 patches series which consolidates the x86 entry code. The larger explanation is in the part I cover letter:
https://lore.kernel.org/r/20200225213636.689276920@linutronix.de
I applies on top of part III which can be found here:
https://lore.kernel.org/r/20200225221606.511535280@linutronix.de
This part consolidates the entry stub ASM code generation further by:
- Converting the more complex exceptions to the new IDTENTRY scheme
- Providing seperate C entry points for #DB and #MC (entry from user/kernel) to make addressing the RCU vs. world issues which were discussed in the last weeks simpler.
- Moving the CR2 read for page fault handlers out of ASM code
This applies on top of part three which is available here:
git://git.kernel.org/pub/scm/linux/kernel/git/tglx/devel.git entry-v1-part3
To get part 1 - 4 pull from here:
git://git.kernel.org/pub/scm/linux/kernel/git/tglx/devel.git entry-v1-part4
Thanks,
tglx
