This branch is almost exclusively dead code removal based on those annotations. Some device driver removals went through separate subsystem trees, but the majority is in the same branch, in order to better handle dependencies between the patches and avoid breaking bisection. Unfortunately that leads to merge conflicts against other changes in the subsystem trees, but they should all be trivial to resolve by removing the files. See commit 7d0d3fa7339e ("Merge tag 'arm-boardfiles-6.0' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc") for the description of which machines were marked unused and are now removed.

It's needed as the PCIe controller found on the SoC depends on 64bit addressing, yet can't be included as not all v7 boards support LPAE. Introduce multi_v7_lpae_defconfig, built off multi_v7_defconfig, which will avoid us having to duplicate and maintain multiple similar configurations. Needless to say the Raspberry Pi 4 is not the only platform that can benefit from this new configuration.

Commit 59e2cf8d21e0 ("ARM: 9275/1: Drop '-mthumb' from AFLAGS_ISA") followed up on this by removing -mthumb from AFLAGS so that __thumb2__ would not be defined when the default target was ARMv7 or newer. Unfortunately, the second commit's fix assumes that the toolchain defaults to -mno-thumb / -marm, which is not the case for Debian's arm-linux-gnueabihf target, which defaults to -mthumb: $ echo | arm-linux-gnueabihf-gcc -dM -E - | grep __thumb #define __thumb2__ 1 #define __thumb__ 1 This target is used by several CI systems, which will still see redefined macro warnings, despite '-mthumb' not being present in the flags: <command-line>: warning: "__thumb2__" redefined <built-in>: note: this is the location of the previous definition Remove the global AFLAGS __thumb2__ define and move it to the crypto folder where it is required by the imported OpenSSL algorithms; the rest of the kernel should use the internal CONFIG_THUMB2_KERNEL symbol to know whether or not Thumb2 is being used or not. Be sure that __thumb2__ is undefined first so that there are no macro redefinition warnings.
