Subject: [PATCHv3 00/24] ILP32 support in ARM64
Date: Wed, 3 Sep 2014 14:18:54 -0700 [thread overview]
Message-ID: <1409779158-30963-1-git-send-email-apinski@cavium.com> (raw)
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
