[PATCH AUTOSEL 6.7 40/58] LoongArch: Select HAVE_ARCH_SECCOMP to use the common SECCOMP menu

From: Masahiro Yamada <masahiroy@kernel.org>

[ Upstream commit 6b79ecd084c99b31c8b4d0beda08893716d5558e ]

LoongArch missed the refactoring made by commit 282a181b1a0d ("seccomp:
Move config option SECCOMP to arch/Kconfig") because LoongArch was not
mainlined at that time.

The 'depends on PROC_FS' statement is stale as described in that commit.
Select HAVE_ARCH_SECCOMP, and remove the duplicated config entry.

This is limited by the size of the lower address memory, 256MB.

-config SECCOMP
- bool "Enable seccomp to safely compute untrusted bytecode"
- depends on PROC_FS
- default y
- help
- This kernel feature is useful for number crunching applications
- that may need to compute untrusted bytecode during their
- execution. By using pipes or other transports made available to
- the process as file descriptors supporting the read/write
- syscalls, it's possible to isolate those applications in
- their own address space using seccomp. Once seccomp is
- enabled via /proc/<pid>/seccomp, it cannot be disabled
- and the task is only allowed to execute a few safe syscalls
- defined by each seccomp mode.
-
- If unsure, say Y. Only embedded should say N here.
