2022-03-11um: Remove duplicated include in syscalls_64.cYang Li1-1/+0
Fix following includecheck warning: ./arch/x86/um/syscalls_64.c: registers.h is included more than once. Reported-by: Abaci Robot <abaci@linux.alibaba.com> Fixes: dbba7f704aa0 ("um: stop polluting the namespace with registers.h contents") Signed-off-by: Yang Li <yang.lee@linux.alibaba.com> Signed-off-by: Richard Weinberger <richard@nod.at>
2021-12-21um: stop polluting the namespace with registers.h contentsAl Viro1-0/+1
Only one extern in there is needed in processor-generic.h, and it's not needed anywhere else. So move it over there and get rid of the include in processor-generic.h, adding includes of registers.h to the few files that need the declarations in it.

2021-12-21um: registers: Rename function names to avoid conflicts and build problemsRandy Dunlap1-1/+2
The function names init_registers() and restore_registers() are used in several net/ethernet/ and gpu/drm/ drivers for other purposes (not calls to UML functions), so rename them. This fixes multiple build errors.

2017-03-21um/arch_prctl: Fix fallout from x86 arch_prctl() reworkKyle Huey1-1/+1
The recent arch_prctl rework added a bracket instead of a comma. Fix it.

2017-03-20x86/arch_prctl/64: Rename do_arch_prctl() to do_arch_prctl_64()Kyle Huey1-7/+7
In order to introduce new arch_prctls that are not 64 bit only, rename the existing 64 bit implementation to do_arch_prctl_64(). Also rename the second argument of that function from 'addr' to 'arg2', because it will no longer always be an address.

2017-03-20x86/arch_prctl: Rename 'code' argument to 'option'Kyle Huey1-6/+7
The x86 specific arch_prctl() arbitrarily changed prctl's 'option' to 'code'. Before adding new options, rename it.

we only use that to tell copy_thread() done by syscall from that done by kernel_thread(). However, it's easier to do simply by checking PF_KTHREAD in thread flags. Merge sys_clone() guts for 32bit and 64bit, while we are at it... Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
