[PATCH 0/1] MR4874: ntdll: Fix exception list offset in call_user_mode_callback / user_mode_callback_return.

[Paul Gofman (＠gofman)]

The size allocated on stack is 0x400 (sizeof(syscall_frame)) + 8 bytes for the exception ptr, so ptr is supposed to go at 0x400, not 0x408. That currently works because of lucky 64 bytes alignment.
