+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.

+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.
