Subject: [musl] [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.
