This is necessary because on some 64bit machines the high-order 32bits are being clobbered by the firmware call, and thus we failed to bring up secondary CPUs (and instead crashed the kernel) in some situations eg if we had more than 4GB RAM. This patch fixes a bug which has been since ever in the parisc linux kernel and which prevented some people to use a 64bit kernel" * 'parisc-3.12' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux: parisc: Do not crash 64bit SMP kernels on machines with >= 4GB RAM 2013-10-27T17:29:25Z Linus Torvalds torvalds@linux-foundation.org 2013-10-27T17:29:25Z urn:sha1:aff22d3f1a8abef4d28817e0d762b3054e39cf7a Pull timer fix from Ingo Molnar: "This tree contains a clockevents regression fix for certain ARM subarchitectures" * 'timers-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: clockevents: Sanitize ticks to nsec conversion 2013-10-27T17:28:35Z Linus Torvalds torvalds@linux-foundation.org 2013-10-27T17:28:35Z urn:sha1:e2756f5e0fab825d08dcfbbe6b235166035fa501 Pull perf fixes from Ingo Molnar: "The tree contains three fixes: - Two tooling fixes - Reversal of the new 'MMAP2' extended mmap record ABI, introduced in this merge window.

This includes a number of EXTENDED_COPY related fixes as a result of Thomas and Doug's continuing testing and feedback. Also included is an important vhost/scsi fix that addresses a long standing issue where the 'write' parameter for get_user_pages_fast() was incorrectly set for virtio-scsi WRITEs -> DMA_TO_DEVICE, and not for virtio-scsi READs -> DMA_FROM_DEVICE. This resulted in random userspace segfaults and other unpleasantness on KVM host, and unfortunately has been an issue since the initial merge of vhost/scsi in v3.6.

The reason was unclear, esp. since it involved various machines (e.g. J5600, J6750 and SuperDome). Testing showed, that those crashes didn't happened when less than 4GB were installed, or if a 32bit Linux kernel was booted. In the end, the fix for those SMP problems is trivial: During the early phase of the initialization of the CPUs, including the monarch CPU, the PDC_PSW firmware function to enable WIDE (=64bit) mode is called. It's documented that this firmware function may clobber various registers, and one one of those possibly clobbered registers is %cr30 which holds the task thread info pointer. Now, if %cr30 would always have been clobbered, then this bug would have been detected much earlier. But lots of testing finally showed, that - at least for %cr30 - on some machines only the upper 32bits of the 64bit register suddenly turned zero after the firmware call. So, after finding the root cause, the explanation for the various crashes became clear: - On 32bit SMP Linux kernels all upper 32bit were zero, so we didn't faced this problem. - Monarch CPUs in 64bit mode always booted sucessfully, because the inital task thread info pointer was below 4GB. - Secondary CPUs booted sucessfully on machines with less than 4GB RAM because the upper 32bit were zero anyay. - Secondary CPus failed to boot if we had more than 4GB RAM and the task thread info pointer was located above the 4GB boundary. Finally, the patch to fix this problem is trivial by saving the %cr30 register before the firmware call and restoring it afterwards.
