Subject: [PATCH v3 4/6] mips: remove syscall table entries
Date: Thu, 29 Nov 2018 14:13:34 +0530 [thread overview]
Message-ID: <1543481016-18500-5-git-send-email-firoz.khan@linaro.org> (raw)
In-Reply-To: <1543481016-18500-1-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.
