| | | | | | | | | | | The Asus WL520GC and WL520GU are based on the BCM5354 and clocked at 200MHz, but they do not have a clkfreq nvram variable set to the correct value.

* MIPS: BCM47XX: Fix clock detection for BCM5354 with 200MHz clockHauke Mehrtens2013-10-291-0/+12
| | | | | | | | | | | | Some BCM5354 SoCs are running at 200MHz, but it is not possible to read the clock from a register like it is done on some other SoC in ssb and bcma. These devices should have a clkfreq nvram configuration value set to 200, read it and set the clock to the correct value.

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
| * parisc: Do not crash 64bit SMP kernels on machines with >= 4GB RAMHelge Deller2013-10-271-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since the beginning of the parisc-linux port, sometimes 64bit SMP kernels were not able to bring up other CPUs than the monarch CPU and instead crashed the kernel. 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.

The reason is, that the clockevents core code converts the minimal hardware tick delta to a nanosecond value for core internal usage. This conversion is affected by integer math rounding loss, so the backwards conversion to hardware ticks will likely result in a value which is less than the configured hardware limitation. The affected subarchs used their own workaround (SIGH!) which got lost in the conversion. The solution for the issue at hand is simple: adding evt->mult - 1 to the shifted value before the integer divison in the core conversion function takes care of it. But this only works for the case where for the scaled math mult/shift pair "mult <= 1 << shift" is true. For the case where "mult > 1 << shift" we can apply the rounding add only for the minimum delta value to make sure that the backward conversion is not less than the given hardware limit. For the upper bound we need to omit the rounding add, because the backwards conversion is always larger than the original latch value. That would violate the upper bound of the hardware device. Though looking closer at the details of that function reveals another bogosity: The upper bounds check is broken as well. Checking for a resulting "clc" value greater than KTIME_MAX after the conversion is pointless. The conversion does: u64 clc = (latch << evt->shift) / evt->mult; So there is no sanity check for (latch << evt->shift) exceeding the 64bit boundary. The latch argument is "unsigned long", so on a 64bit arch the handed in argument could easily lead to an unnoticed shift overflow. With the above rounding fix applied the calculation before the divison is: u64 clc = (latch << evt->shift) + evt->mult - 1; So we need to make sure, that neither the shift nor the rounding add is overflowing the u64 boundary.

We have identified cases where it would not report the correct mapping information, clone(VM_CLONE) but with separate pids. We will revisit the support once we find a solution for this case. The patch changes the kernel to return EINVAL if attr->mmap2 is set. The patch also modifies the perf tool to use regular PERF_RECORD_MMAP for synthetic events and it also prevents the tool from requesting attr->mmap2 mode because the kernel would reject it. The support will be revisited once the kenrel interface is updated. In V2, we reduce the patch to the strict minimum. In V3, we avoid calling perf_event_open() with mmap2 set because we know it will fail and require fallback retry.

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.

However, this parameter is intended to signal WRITEs to pinned userspace PTEs for the virtio-scsi DMA_FROM_DEVICE -> READ payload case, and *not* for the virtio-scsi DMA_TO_DEVICE -> WRITE payload case. This bug would manifest itself as random process segmentation faults on KVM host after repeated vhost starts + stops and/or with lots of vhost endpoints + LUNs.

Commit 2febcdf84b ("mtd: gpmi: set the BCHs geometry with the ecc info") makes the driver use the ECC info (ECC strength and ECC step size) provided by the MTD code, and creates a different NAND ECC layout for the BCH, and use the new ECC layout. This causes a regression: We can not mount the ubifs which was created by the old NAND ECC layout. This patch fixes this issue by reverting to the legacy ECC layout. We will probably introduce a new device-tree property to indicate that the new ECC layout can be used. For now though, for the imminent 3.12 release, we just unconditionally revert to the 3.11 behaviour. This leaves a harmless cosmetic warning about an unused function.

Instead use the provided by the platform_device. The MTD name was changed to use the one provided by the platform_device. However, this can be problematic as some users want to set partitions using the kernel parameter 'mtdparts', where the name is needed. Therefore, to avoid regressions in users relying in 'mtdparts' we revert the change and use the previous one 'pxa3xx_nand-0'. While at it, let's put a big comment and prevent this change from happening ever again.
