Subject: [PATCH v4 0/9] ARM: remove set_fs callers and implementation
Date: Fri, 30 Oct 2020 16:45:10 +0100 [thread overview]
Message-ID: <20201030154519.1245983-1-arnd@kernel.org> (raw)
From: Arnd Bergmann <arnd@arndb.de>
Hi Christoph, Russell,
This is the rebased version of my ARM set_fs patches on top of
v5.10-rc1, dropping the TASK_SIZE_MAX patch but leaving everything
else unchanged.
I have tested the oabi-compat changes using the LTP tests for the three
modified syscalls using an Armv7 kernel and a Debian 5 OABI user space.
I also tested the syscall_get_nr() in all combinations of OABI/EABI
kernel user space and fixed the bugs I found after Russell pointed
out one of those issues.
Russell, you can pull these from
https://git.kernel.org/pub/scm/linux/kernel/git/arnd/playground.git arm-setfs_v4
or I can add them to the ARM patch tracker if you prefer.
Arnd
