Subject: [GIT] kbuild fixes
Hi Linus.
- various .gitignore updates
- disabling of -Wformat-security
We looked at it and 'fixing' the warnings was not pleasant
- fixes/improvements for the newly introduced macros in asm-generic/vmlinux.lds.h
Nothing earth-shaking..
And it has been in -next for a few days with no issues.
I am heading for a two week vacation in Sweden and will
be offline in that period.
Enjoy the kernel hacking while I enjoy my vacation :-)
Sam
