Linus Torvalds' entire Linux 4.5-rc5 release message was short and sweet, "Things continue to look normal, and things hav ebeen fairly calm. Yes, the VM THP cleanup seems to still be problematic on s390, but other than that I don't see anything particularly worrisome. So another week, another rc. The patch looks pretty normal, with about 55% drivers (drm and clk drivers stand out, but aren't alone) and almost 20% arch updates (arm, m68k, powerpc, s390, x86). The rest is spread out - filesystems (ext4, efi, cifs), some core kernel and header files. And a few documentation updates. Everything fairly small."
There aren't any AMDGPU/Radeon DRM fixes this week. If you are not familiar with the new Linux 4.5 features, see our feature overview. Linux 4.5 will be officially released likely in three or four weeks.
