Linux Kernel 4.4 RC1 released
The driver changes are all over, although staging, networking and GPU drivers stand out (and those three areas account for over half of the driver changes – roughly 40% of the whole patch). On the architecture side, ARM (when counting both 32-bit and 64-bit) accounts for about half the changes, with x86, powerpc, mips, chris and s390 accounting for the other half.
