Subject: [PATCH AUTOSEL 6.6 34/51] LoongArch: Select HAVE_ARCH_SECCOMP to use the common SECCOMP menu

From: Masahiro Yamada <masahiroy@...nel.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 kernel feature is useful for number crunching applications

-	  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.
