Subject: [PATCH] ntdll: Always align stack pointer in
__wine_syscall_dispatcher on x64.
Syscall thunks break stack alignment for dispatcher. Regardless of that,
it is probably better not to assume aligned stack in syscall thunk entry.

Subject: [PATCH] winebuild: Call __wine_syscall_dispatcher through the fixed
address.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Based on a patch by Erich E. Hoover and Michael Müller.
Helps applications which directly load ntdll.dll from disk and
call syscall thunks from the loaded image.
