Subject: [PATCH v3 3/7] riscv: Delete asm/compat.h
Date:   Fri,  6 Jul 2018 22:42:43 -0700
Message-Id: <20180707054247.19802-4-deepa.kernel@gmail.com>
In-Reply-To: <20180707054247.19802-1-deepa.kernel@gmail.com>
References: <20180707054247.19802-1-deepa.kernel@gmail.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

riscv does not enable CONFIG_COMPAT in default configurations:
defconfig, allmodconfig and allnoconfig.
Remove the asm/compat.h as it does not seem to add any value to
the architecture without CONFIG_COMPAT.

Now that time compat syscalls are being reused in non CONFIG_COMPAT
modes, asm-generic/compat.h provides definitions for riscv 32 bit
mode.

Alternative would be to make compat_time.h to be conditional on
CONFIG_COMPAT_32BIT_TIME. But, since riscv does not does not need
asm/compat.h, delete it instead.
