migrate_enable() can be called with current->state != TASK_RUNNING.
Avoid clobbering the existing state by using stop_one_cpu_nowait().
Since we're stopping the current cpu, we know that we won't get

Makes sense, I agree with you. But still, there's no
formal/right/single way to do kdump, so I don't thin
__get_user_asm macro leaves result register uninitialized when alignment
check fails. Add 'insn' parameter to __check_align_{1,2,4} and pass an
instruction that initializes result register from __get_user_asm.

__get_user_[no]check uses temporary buffer of type long to store result
of __get_user_size and do sign extension on it when necessary. This
doesn't work correctly for 64-bit data. Fix it by moving temporary
buffer/sign extension logic to __get_user_asm.
Don't do assignment of __get_user_bad result
Hello,
this series fixes return value, out-of-bound stack access and value
truncation in xtensa implementation of {get,put}_user() for 64bit
values. It also cleans up naming of assembly parameters in
__{get,put}_user_asm and __check_align_{1,2,4}.
Changes v1->v2:
- initialize result when access_o
Numeric assembly arguments are hard to understand and assembly code that
uses them is hard to modify. Use named arguments in __check_align_*,
__get_user_asm and __put_user_asm. Modify macro parameter names so that
they don't affect argument names.

First of all, on short copies __copy_{to,from}_user() return the amount
of bytes left uncopied, *not* -EFAULT. get_user() and put_user() are
expected to return -EFAULT on failure.
Another problem is get_user(v32, (__u64 __user *)p); that should
fetch 64bit value and the assign it
