um: Do not rely on libc to provide modify_ldt()

2015-10-19T20:53:37Z

modify_ldt() was declared as an external symbol. Despite the man page for this syscall telling that there is no wrapper in glibc, since version 2.1 there actually is, so linking to the glibc works. Since modify_ldt() is not a POSIX interface, other libc implementations do not always provide a wrapper function. Even glibc headers do not provide a corresponding declaration. So go the recommended way to call this using syscall(). Signed-off-by: Hans-Werner Hilse Signed-off-by: Richard Weinberger

um: Don't pollute kernel namespace with uapi

2015-06-25T20:44:11Z

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

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.

um: Stop abusing KERNEL

2015-05-31T20:05:32Z

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
