Bump to version v0.9.9

[joe-lawrence]

Updates of interest:
v0.9.9:

• Support for gcc-13
• Support for Linux 6.2
• Support for UBSAN kernels
• Fix handling of PowerPC cpu features
• Added RHEL-8.8 and 9.2 integration tests

Kpatch tools are mature enough and are widely used today. Perhaps, it is time to set version to 1.0 instead of 0.x?
@joe-lawrence @jpoimboe, what do you think?

Looks good to me.

I'm fine with that. Or we could do 1.0 next time, after the bot closes all the stale bugs.

I was hoping to merge the v0.9.9 tag today, but for v1.0 should we finally remove the deprecated kpatch.ko module? There's a lot of "experimental" type warnings in the README.md as well that could possibly be toned down.

Makes sense. I can open an issue to track what we want to do for 1.0.

Fine by me. Thanks!

Yes, I agree, it is time for kpatch.ko to go away.
