um: Don't pollute kernel namespace with uapi

2015-06-25T20:44:11+00:00

Don't include ptrace uapi stuff in arch headers, it will pollute the kernel namespace and conflict with existing stuff. In this case it fixes clashes with common names like R8. Signed-off-by: Richard Weinberger

Merge branch 'x86/asm' into x86/core, to prepare for new patch

2015-06-08T18:48:20+00:00

Collect all changes to arch/x86/entry/entry_64.S, before applying patch that changes most of the file. Signed-off-by: Ingo Molnar

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

2015-06-04T05:37:33+00:00

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.

um: Stop abusing KERNEL

2015-05-31T20:05:32+00:00

Currently UML is abusing __KERNEL__ to distinguish between kernel and host code (os-Linux). It is better to use a custom define such that existing users of __KERNEL__ don't get confused. Signed-off-by: Richard Weinberger

um: Fix warning in setup_signal_stack_si()

2015-05-31T15:39:19+00:00

Fixes: arch/x86/um/signal.c: In function ‘setup_signal_stack_si’: include/asm-generic/uaccess.h:146:27: warning: initialization from incompatible pointer type [enabled by default] __typeof__(*(ptr)) __x = (x); \ ^ arch/x86/um/signal.c:544:10: note: in expansion of macro ‘__put_user’ err |= __put_user(ksig->ka.sa.sa_restorer, Signed-off-by: Richard Weinberger

um: Rework uaccess code

2015-05-31T15:32:36+00:00

Rework UML's uaccess code to reuse as much as possible from asm-generic/uaccess.c. Signed-off-by: Richard Weinberger

um: Add uaccess.h to ldt.c

2015-05-31T15:32:03+00:00

...for userspace memory access. Signed-off-by: Richard Weinberger

um: Add uaccess.h to syscalls_64.c

2015-05-31T15:31:56+00:00

It's using put_user() and needs this header. Signed-off-by: Richard Weinberger

um: Add asm/elf.h to vma.c

2015-05-31T15:31:50+00:00

um_vdso_addr is defined in asm/elf.h. Signed-off-by: Richard Weinberger
