Now that v3.6 of the kernel has been released, is it available in any trusted PPAs? If not, I don't mind compiling it on my machine itself (I have never done it before though). I'd love it if I had step-by-step instructions.
Download kernel files from http://kernel.ubuntu.com/~kernel-ppa/mainline/. Like for kernel v3.7.1-raring download your required files. For x86_64 download the "amd64" files, for x86 download the "i386" files, for ARM download the "armhf" files. And for all architectures download the "all" file. Then put them in a folder, like in Downloads/kernel. Then from terminal go to that folder, like "cd ~/Downloads/kernel". Then run "sudo dpkg -i linux-*.deb", enter password when prompted. When installation completes, restart. That's all. You can check your kernel version by entering "uname -a". Thanks.
