Subject: [PATCH v4 5/7] mips: remove syscall table entries
Date: Thu,  6 Dec 2018 10:48:26 +0530	[thread overview]
Message-ID: <1544073508-13720-6-git-send-email-firoz.khan@linaro.org> (raw)
In-Reply-To: <1544073508-13720-1-git-send-email-firoz.khan@linaro.org>

The config flag - CONFIG_MIPS_MT_FPAFF uses to check whether which
syscall entries need to be used in scall32-o32.S file.

One of the patch in this patch series will generate syscall table
file. But CONFIG_MIPS_MT_FPAFF flag will add more complexity in the
script to generate the syscall table file.

In order to come up with a common implementation across all archit-
ecture, we need to remove mipsmt_sys_sched_setaffinity and mipsmt-
_sys_sched_getaffinity from the table and define it in other way.
