Subject: [PATCH 00/13] Update csky subsystem for linux-5.9-rc1
Date: Sat,  1 Aug 2020 01:14:00 +0000
Message-ID: <1596244453-98575-1-git-send-email-guoren@kernel.org> (raw)

From: Guo Ren <guoren@linux.alibaba.com>

Here are the patchess for the next linux version. Add features
(seccomp-filter, err-injection, top-down&random mmap-layout, irq_work,
show_ipi, context-tracking), and fixup (kprobe_on_ftrace, ...),
Optimize (fault print, ...).

I think we'll finish most of features for arch/csky this year :) 

Guo Ren (12):
  csky: Add SECCOMP_FILTER supported
  csky: Add cpu feature register hint for smp
  csky: Fixup duplicated restore sp in RESTORE_REGS_FTRACE
  csky: Fixup kprobes handler couldn't change pc
  csky: Add support for function error injection
  csky: Optimize the trap processing flow
  csky: Use top-down mmap layout
  csky: Set CONFIG_NR_CPU 4 as default
  csky: Fixup warning by EXPORT_SYMBOL(kmap)
  csky: Add irq_work support
  csky: Add arch_show_interrupts for IPI interrupts
  csky: Add context tracking support

Tobias Klauser (1):
  csky: remove unusued thread_saved_pc and *_segments functions/macros
