Subject: [PATCH 21/27] [AARCH64] ILP32: introduce syscalls that pass off_t
Date: Tue, 21 Jun 2016 08:07:05 +0300 [thread overview]
Message-ID: <1466485631-3532-23-git-send-email-ynorov@caviumnetworks.com> (raw)
In-Reply-To: <1466485631-3532-1-git-send-email-ynorov@caviumnetworks.com>
From: Yury Norov <yury.norov@gmail.com>
ILP32 has 64-bit off_t, to follow modern requirements.
But kernel clears top-halves of input registers. It means
we have to pass corresponding arguments in a pair, like
aarch32 does. In this patch all affected syscalls are redefined.
Most of them are taken from arm code.
