Subject: [PATCH 08/24] Allow a 32bit ABI to use the naming of the 64bit ABI syscalls to avoid confusion of not splitting the registers.
Date: Sat, 24 May 2014 00:02:03 -0700 [thread overview]
Message-ID: <1400914939-9708-9-git-send-email-apinski@cavium.com> (raw)
In-Reply-To: <1400914939-9708-1-git-send-email-apinski@cavium.com>
In the ARM64 ILP32 case, we want to say the syscalls that normally would pass 64bit as two arguments are now passing as one so want to use the 64bit naming scheme.
Thanks,
Andrew Pinski
