From mboxrd@z Thu Jan 1 00:00:00 1970 From: Helge Deller Subject: [GIT PULL] parisc updates for v3.12-rc5 Date: Sun, 13 Oct 2013 18:11:30 +0200 Message-ID: <20131013161130.GA19534@p100.box> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii To: Linus Torvalds , Linux Kernel Development , linux-parisc@vger.kernel.org, James Bottomley Return-path: List-ID: List-Id: linux-parisc.vger.kernel.org Hi Linus, Please pull the latest parisc fixes from git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux.git parisc-3.12 This patchset includes a bugfix to prevent a kernel crash when memory in page zero is accessed by the kernel itself, e.g. via probe_kernel_read(). Furthermore we now export flush_cache_page() which is needed (indirectly) by the lustre filesystem. The other patches remove unused functions and optimizes the page fault handler to only evaluate variables if needed, which again protects against possible kernel crashes. Thanks, Helge ---------------------------------------------------------------- Geert Uytterhoeven (1): parisc: Export flush_cache_page() (needed by lustre) Helge Deller (4): parisc: remove unused syscall_ipi() function. parisc: mark parisc_terminate() noreturn and cold. parisc: fix interruption handler to respect pagefault_disable() parisc: let probe_kernel_read() capture access to page zero Jiang Liu (1): parisc: kill SMP single function call interrupt John David Anglin (1): parisc: optimize variable initialization in do_page_fault arch/parisc/include/asm/traps.h | 2 +- arch/parisc/kernel/cache.c | 1 + arch/parisc/kernel/smp.c | 8 +------- arch/parisc/kernel/traps.c | 11 +++-------- arch/parisc/lib/memcpy.c | 15 ++++++++++++++- arch/parisc/mm/fault.c | 15 ++++++++++----- 6 files changed, 30 insertions(+), 22 deletions(-)
