It is an idea of running codespell as part of our presubmit checks.
Before enabling it for new changes, let's fix what it has found.

Instead of passing the event mask at registratrion time, pass the mask as part
of the waiter. This makes the mask immutable and simplifies the architecture of
waiters. This is also necessary for a future fix that will allow the fdnotifier
to keep persistent entries, as opposed to requiring constant updates.
This change is intended to be a no-op in terms of function. The only exception
is signalfd, where this mask was abused. To handle this case, the operation of
signalfd changed to allow one layer of indirection.

Previously, we weren't making a copy when a sysv message queue was
receiving a message with the MSG_COPY flag. This flag indicates the
message being received should be left in the queue and a copy of the
message should be returned to userspace. Without the copy, a racing
process can modify the original message while it's being marshalled to
user memory.

For IPCInfo, update value of MSGSEG constant in abi to avoid overflow in
MsgInfo.MsgSeg. MSGSEG was originaly simplified in abi, and is unused
(by us and within the kernel), so updating it is okay.
