NAME

       kgdb_skipexception - (optional) exit kgdb_handle_exception early

SYNOPSIS

       int kgdb_skipexception(int exception, struct pt_regs * regs);

ARGUMENTS

       exception
	   Exception vector number

       regs
	   Current struct pt_regs.

DESCRIPTION

       On some architectures it is required to skip a breakpoint exception when it occurs after a breakpoint has been removed. This can be
       implemented in the architecture specific portion of kgdb.

NAME

       swapcontext - Swap out old context with new context

SYNOPSIS

       int sys_swapcontext (struct ucontext *old_ctx, struct ucontext *new_ctx, int r5, int r6, int r7, int r8, struct pt_regs *regs);

DESCRIPTION

       swapcontext  swaps out context old_ctx with new context new_ctx. The int r# values have no place in the system call functionality. The regs
       value indicates the current user register values from the user stack.

RETURN VALUE

       swapcontext returns 0 on success; otherwise, swapcontext returns one of the errors listed in the "Errors" section.

ERRORS

       -EFAULT
	      swapcontext could not verify that the memory area pointed to by old_ctx or new_ctx was accessible for the operation.

       -SIGSEGV
	      A fault occurred when the context was being copied into the kernel's image of the user's registers. The should only occur in an out-
	      of-memory situation.
