-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.
