[Linux-stable-mirror] Patch "powerpc/64: Fix flush_(d|i)cache_range() called from modules" has been added to the 4.4-stable tree

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled powerpc/64: Fix flush_(d|i)cache_range() called from modules to the 4.4-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=sum… The filename of the patch is: powerpc-64-fix-flush_-d-i-cache_range-called-from-modules.patch and it can be found in the queue-4.4 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable(a)vger.kernel.org> know about it. >From 8f5f525d5b83f7d76a6baf9c4e94d4bf312ea7f6 Mon Sep 17 00:00:00 2001 From: Oliver O'Halloran <oohall(a)gmail.com> Date: Mon, 3 Apr 2017 13:25:12 +1000 Subject: powerpc/64: Fix flush_(d|i)cache_range() called from modules From: Oliver O'Halloran <oohall(a)gmail.com> commit 8f5f525d5b83f7d76a6baf9c4e94d4bf312ea7f6 upstream. When the kernel is compiled to use 64bit ABIv2 the _GLOBAL() macro does not include a global entry point. A function's global entry point is used when the function is called from a different TOC context and in the kernel this typically means a call from a module into the vmlinux (or vice-versa). There are a few exported asm functions declared with _GLOBAL() and calling them from a module will likely crash the kernel since any TOC relative load will yield garbage. flush_icache_range() and flush_dcache_range() are both exported to modules, and use the TOC, so must use _GLOBAL_TOC().

The rfid/hrfid ((Hypervisor) Return From Interrupt) instruction is used for switching from the kernel to userspace, and from the hypervisor to the guest kernel. However it can and is also used for other transitions, eg. from real mode kernel code to virtual mode kernel code, and it's not always clear from the code what the destination context is. To make it clearer when reading the code, add macros which encode the expected destination context.

[Linux-stable-mirror] [PATCH v4.4 backport 00/16] powerpc stable backports for v4.4

by Michael Ellerman

Hi Greg, This is a backport to v4.4 of the RFI flush series that went upstream recently. There's also a few other commits I noticed had not made it to v4.4 due to needing manual backports. cheers
