-Subject: [PATCH] fs: binfmt_elf_efpic: fix personality for fdpic ELF
-
-The elf-fdpic loader hard sets the process personality to either
-PER_LINUX_FDPIC for true elf-fdpic binaries or to PER_LINUX for
-normal ELF binaries (in this case they would be constant displacement
-compiled with -pie for example). The problem with that is that it
-will lose any other bits that may be in the ELF header personality
-(such as the "bug emulation" bits).
-
-On the ARM architecture the ADDR_LIMIT_32BIT flag is used to signify
-a normal 32bit binary - as opposed to a legacy 26bit address binary.
-This matters since start_thread() will set the ARM CPSR register as
-required based on this flag. If the elf-fdpic loader loses this bit
-the process will be mis-configured and crash out pretty quickly.
-
-Modify elf-fdpic loaders personality setting binaries so that it
-preserves the upper three bytes by using the SET_PERSONALITY macro
-to set it. This macro in the generic case sets PER_LINUX and preserves
-the upper bytes. Architectures can override this for their specific
-use case, and ARM does exactly this.
-
-The problem shows up quite easily runing under qemu, but not necessarily
-on all types of real ARM hardware. If the underlying ARM processor does
-not support the legacy 26-bit addressing mode then everyting will work
-as expected.

-Subject: [PATCH] ARM: start_thread: restore registers on ELF load for noMMU
-
-The binfmt_elf-fdpic loader is capable of loading constant displacement
-ELF format binaries (like those compiled -pie) on noMMU systems as well
-as elf-fdpic format binaries. The traditional ELF loader cannot be
-enabled on noMMU systems.
-
-Commit 5e588114329c ("ARM: start_thread(): don't always clear all regs")
-fixed the start_thread() code so that it maintains the required
-elf-fdpic registers through to the new process, but it only does that if
-current has its personality FDPIC_FUNCPTRS bit set. That is true for
-elf-fdpic format binaries but will not be true for non-fdpic ELF
-binaries.
-
-Modify the test of the FDPIC_FUNCPTRS personality bit to also carry out
-the register restore if this is a noMMU system. This is not perfect,
-since it will also preserve these registers on noMMU systems for all
-binary format types (could be flat format for example). That won't break
-anything, but it is potentially leaking some information into the new
-process. But for the noMMU case we need those start time registers set to
-be able to finalize the runtime loading of the -pie style ELF binary
-(carry out its segment and dynamic relocation processing).
-
-Unfortunately the FDPIC_FUNCPTRS flag cannot just be enabled for all
-elf-fdpic loaded binaries. That personality bit is used for other things
-like the controlling the changed behavior for signal handling.
-
-There is no change in behavior for normal ELF loading on MMU systems.
-A -pie style ELF binary built for noMMU systems can be load and run using
-the usual ELF loader on an MMU system (elf-fdpic loader not required in
-this case).

-Subject: [PATCH] ARM: versatile: support configuring versatile machine for no-MMU
-
-Allow the arm versatile machine to be configured for no-MMU operation.
-
-Older kernels had the ability to build the versatile machine with the MMU
-disabled (!CONFIG_MMU). Recent changes to convert the versatile machine
-to device tree lost this ability. (Although older kernels could be built
-they did not run due to a bug in the IO_ADDRESS() mapping on this machine).
-
-The motivation for this is that the versatile machine is well supported
-in qemu. And this provides an excellent platform for development and
-testing no-MMU support on ARM in general.
-
-This patch adds a versatile platform selection in the upper level arm
-system type menu - where it appeared in older kernel versions - when
-configuring for the no-MMU case. There is no visible change to the way
-versatile is selected for the MMU enabled case.
