x86/entry: Move C entry and exit code to arch/x86/entry/common.c

2015-07-07T08:59:05Z

The entry and exit C helpers were confusingly scattered between ptrace.c and signal.c, even though they aren't specific to ptrace or signal handling. Move them together in a new file. This change just moves code around. It doesn't change anything.

x86/asm/entry/64/compat: Rename ia32entry.S -> entry_64_compat.S

2015-06-07T12:56:50Z

So we now have the following system entry code related files, which define the following system call instruction and other entry paths: entry_32.S # 32-bit binaries on 32-bit kernels entry_64.S # 64-bit binaries on 64-bit kernels entry_64_compat.S # 32-bit binaries on 64-bit kernels Cc: Alexei Starovoitov Cc: Andrew Morton Cc: Andy Lutomirski Cc: Borislav Petkov Cc: Brian Gerst Cc: Denys Vlasenko Cc: Frederic Weisbecker Cc: H.

x86/asm/entry: Move the vsyscall code to arch/x86/entry/vsyscall/

2015-06-04T05:37:37Z

The vsyscall code is entry code too, so move it to arch/x86/entry/vsyscall/. Cc: Borislav Petkov Cc: H. Peter Anvin Cc: Linus Torvalds Cc: Thomas Gleixner Cc: Andy Lutomirski Cc: Denys Vlasenko Cc: Brian Gerst Cc: Peter Zijlstra Cc: linux-kernel@vger.kernel.org Signed-off-by: Ingo Molnar

x86/asm/entry: Move the 'thunk' functions to arch/x86/entry/

2015-06-04T05:37:33Z

These are all calling x86 entry code functions, so move them close to other entry code. Change lib-y to obj-y: there's no real difference between the two as we don't really drop any of them during the linking stage, and obj-y is the more common approach for core kernel object code.

x86/asm/entry: Move entry_64.S and entry_32.S to arch/x86/entry/

2015-06-03T16:51:28Z

Create a new directory hierarchy for the low level x86 entry code: arch/x86/entry/* This will host all the low level glue that is currently scattered all across arch/x86/. Start with entry_64.S and entry_32.S. Cc: Borislav Petkov Cc: H.
