New version with all of the requested changes. Updated to the latest sources.
Notable changes from the previous versions: VDSO code has been factored out to be easier to understand and easier to maintain. Move the config option to the last thing that gets added. Added some extra COMPAT_* macros for core dumping for easier usage.
Andrew Pinski (24): ARM64: Force LP64 to compile the kernel ARM64: Rename COMPAT to AARCH32_EL0 in Kconfig ARM64: Change some CONFIG_COMPAT over to use CONFIG_AARCH32_EL0 instead ARM64:ILP32: Set kernel_long to long long so we can reuse most of the same syscalls as LP64 ARM64:UAPI: Set the correct __BITS_PER_LONG for ILP32 Allow for some signal structures to be the same between a 32bit ABI and the 64bit ABI ARM64:ILP32: Use the same size and layout of the signal structures for ILP32 as for LP64 Allow a 32bit ABI to use the naming of the 64bit ABI syscalls to avoid confusion of not splitting the registers ARM64:ILP32: Use the same syscall names as LP64 ARM64: Introduce is_a32_task/is_a32_thread and TIF_AARCH32 and use them in the correct locations ARM64: Add is_ilp32_compat_task and is_ilp32_compat_thread ARM64:ILP32: COMPAT_USE_64BIT_TIME is true for ILP32 tasks ARM64:ILP32: Use the non compat HWCAP for ILP32 ARM64:ILP32 use the standard start_thread for ILP32 so the processor state is not AARCH32 compat_binfmt_elf: coredump: Allow some core dump macros be overridden for compat. ARM64:ILP32: Support core dump for ILP32 ARM64: Add loading of ILP32 binaries ARM64: Add vdso for ILP32 and use it for the signal return ptrace: Allow compat to use the native siginfo ARM64:ILP32: The native siginfo is used instead of the compat siginfo ARM64:ILP32: Use a seperate syscall table as a few syscalls need to be using the compat syscalls ARM64:ILP32: Fix signal return for ILP32 when the user modified the signal stack ARM64: Add ARM64_ILP32 to Kconfig Add documentation about ARM64 ILP32 ABI
