Subject: [PATCH 19/27] [AARCH64] Add typesizes.h for ILP32
Date: Tue, 21 Jun 2016 08:07:03 +0300	[thread overview]
Message-ID: <1466485631-3532-21-git-send-email-ynorov@caviumnetworks.com> (raw)
In-Reply-To: <1466485631-3532-1-git-send-email-ynorov@caviumnetworks.com>

From: Andrew Pinski <apinski@cavium.com>

The generic typesizes does not work for ILP32 as the kernel long type
needs to be long long (quad).  time_t, off_t, clock_t, suseconds_t,
ino_t, rlim_t are 64bits.
FDSET bitmask is a 64bit type.

* sysdeps/unix/sysv/linux/aarch64/bits/typesizes.h: New file.
