Subject: [PATCH v3 1/7] ia64: add __NR_old_getpagesize in uapi/asm/unistd.h
Date: Thu, 11 Oct 2018 09:54:49 +0530 [thread overview]
Message-ID: <1539231895-4118-2-git-send-email-firoz.khan@linaro.org> (raw)
In-Reply-To: <1539231895-4118-1-git-send-email-firoz.khan@linaro.org>
sys_getpagesize entry is present in entry.S file to support
for old user interface. So we need to add an uapi entry too.
Add __NR_old_getpagesize in order to not break old user space
as it is reserved for backwards compatibility with old __NR_
getpagesize.
