Subject: [PATCH v2 0/9] ARM: remove set_fs callers and implementation
Date: Fri, 18 Sep 2020 14:46:15 +0200 [thread overview]
Message-ID: <20200918124624.1469673-1-arnd@arndb.de> (raw)
Hi Christoph, Russell,
Here is an updated series for removing set_fs() from arch/arm,
based on the previous feedback.
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,
and I have lightly tested the get_kernel_nofault infrastructure by
loading the test_lockup.ko module after setting CONFIG_DEBUG_SPINLOCK.

Arnd Bergmann (9):
mm/maccess: fix unaligned copy_{from,to}_kernel_nofault
ARM: traps: use get_kernel_nofault instead of set_fs()
ARM: oabi-compat: add epoll_pwait handler
ARM: syscall: always store thread_info->syscall
ARM: oabi-compat: rework epoll_wait/epoll_pwait emulation
ARM: oabi-compat: rework sys_semtimedop emulation
ARM: oabi-compat: rework fcntl64() emulation
ARM: uaccess: add __{get,put}_kernel_nofault
ARM: uaccess: remove set_fs() implementation
