Subject: [PATCH v4 1/5] ia64: add __NR_old_getpagesize in uapi header file
Date: Fri, 26 Oct 2018 10:41:10 +0530 [thread overview]
Message-ID: <1540530674-3824-2-git-send-email-firoz.khan@linaro.org> (raw)
In-Reply-To: <1540530674-3824-1-git-send-email-firoz.khan@linaro.org>
sys_getpagesize entry is present in kernel/entry.S file to
support for old user interface. So we need to add an uapi
entry too.
Add __NR_old_getpagesize in uapi/asm/unistd.h in order to
not break old user space as it is reserved for backwards
compatibility with old __NR_getpagesize.
