Given the conflicts, I can provide back-ports once upstream upon request. It should be noted that the backports should be mechanical and trivial (skip non-existent filesystems like orangfs, drop separate inode argument that did not exist in earlier kernels). I will submit the next spin (missed a few filesystems, build errors) with references to the requested stable trees again, so noise will continue. Sincerely -- Mark Salyzyn

[PATCH 2/2] HID: logitech-hidpp: remove support for the G700 over USB

by Benjamin Tissoires

The G700 suffers from the same issue than the G502: when plugging it in, the driver tries to contact it but it fails. This timeout is problematic as it introduce a delay in the boot, and having only the mouse event node means that the hardware macros keys can not be relayed to the userspace.

[4.14 PATCH] lkdtm: support llvm-objcopy

by Nick Desaulniers

commit e9e08a07385e08f1a7f85c5d1e345c21c9564963 upstream. With CONFIG_LKDTM=y and make OBJCOPY=llvm-objcopy, llvm-objcopy errors: llvm-objcopy: error: --set-section-flags=.text conflicts with --rename-section=.text=.rodata Rather than support setting flags then renaming sections vs renaming then setting flags, it's simpler to just change both at the same time via --rename-section. Adding the load flag is required for GNU objcopy to mark .rodata Type as PROGBITS after the rename. This can be verified with: $ readelf -S drivers/misc/lkdtm/rodata_objcopy.o ... Section Headers: [Nr] Name Type Address Offset Size EntSize Flags Link Info Align ... [ 1] .rodata PROGBITS 0000000000000000 00000040 0000000000000004 0000000000000000 A 0 0 4 ... Which shows that .text is now renamed .rodata, the alloc flag A is set, the type is PROGBITS, and the section is not flagged as writeable W.
