Subject: [PATCH 12/15] s390: remove native mmap2() syscall
Date: Thu, 20 Jun 2024 18:23:13 +0200 [thread overview]
Message-ID: <20240620162316.3674955-13-arnd@kernel.org> (raw)
In-Reply-To: <20240620162316.3674955-1-arnd@kernel.org>
From: Arnd Bergmann <arnd@arndb•de>
The mmap2() syscall has never been used on 64-bit s390x and should
have been removed as part of 5a79859ae0f3 ("s390: remove 31 bit
support").
Remove it now.
