When I compiled the following code for ARM, I encountered numerous
errors.
[Test Code]
#include <linux/compiler.h>
#include <linux/uaccess.h>
int foo(int *x, int __user *ptr)
{
return get_user(*x, ptr);
}
To fix the errors, make some asm headers self-contained:
1. In arch/arm/include/asm/domain.h, include <linux/thread_info.h>
for current_thread_info().
2. In arch/arm/include/asm/traps.h, remove unneeded __init, and
include <linux/linkage.h> for asmlinkage.
3. In arch/arm/include/asm/uaccess.h, include <linux/kernel.h> for
might_fault().
