Jason Gerecke authored
The commit which introduced TransducerSerialNumber (368c9664) is missing two crucial implementation details. Firstly, the commit does not set the type/code/bit/max fields as expected later down the code which can cause the driver to crash when a tablet with this usage is connected. Secondly, the call to 'set_bit' causes MSC_PULSELED to be sent instead of the expected MSC_SERIAL. This commit addreses both issues.

We received a report of warning in kernel/sched/core.c where the sched group was NULL on an LPAR after a topology update. This seems to occur because after the topology update has moved the CPUs, cpu_to_node is returning the old value still, which ends up breaking the consistency of the NUMA topology in the per-cpu maps. Ensure that we update the per-cpu fields when we re-map CPUs. Signed-off-by: Nishanth Aravamudan <nacc@linux.vnet.ibm.com> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>

One was that the old hash was not updated before calling the modify code for an ftrace_ops. The second bug was what let the first bug go unnoticed, as the update would check the current hash for all ftrace_ops (where it should only check the old hash for modified ones). This let things work when only one ftrace_ops was registered to a function, but could break if more than one was registered depending on the order of the look ups. The worse thing that can happen if this bug triggers is that the ftrace self checks would find an anomaly and shut itself down" * tag 'trace-fixes-v3.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: ftrace: Fix checking of trampoline ftrace_ops in finding trampoline ftrace: Set ops->old_hash on modifying what an ops hooks to

Will Deacon authored
When unmapping a range of pages in zap_pte_range, the page being unmapped is added to an mmu_gather_batch structure for asynchronous freeing. If we run out of space in the batch structure before the range has been completely unmapped, then we break out of the loop, force a TLB flush and free the pages that we have batched so far. If there are further pages to unmap, then we resume the loop where we left off. Unfortunately, we forget to update addr when we break out of the loop, which causes us to truncate the range being invalidated as the end address is exclusive. When we re-enter the loop at the same address, the page has already been freed and the pte_present test will fail, meaning that we do not reconsider the address for invalidation. This patch fixes the problem by incrementing addr by the PAGE_SIZE before breaking out of the loop on batch failure.

In certain circumstances the PSL (Power Service Layer, which provides translation services for CXL hardware) can send an interrupt for a segment miss that the kernel has already handled. This can happen if multiple translations for the same segment are queued in the PSL before the kernel has restarted the first translation. The CXL driver does not expect this situation and does not check if a segment had already been handled. This could cause a duplicate segment table entry which in turn caused a PSL error taking down the card. This patch fixes the issue by checking for existing entries in the segment table that match the segment we are trying to insert, so as to avoid inserting duplicate entries.

This patch makes copro_calculate_slb() mask the ESID by the correct mask for 1T vs 256M segments. This has no effect by itself as the extra bits were ignored, but it makes debugging the segment table entries easier and means that we can directly compare the ESID values for duplicates without needing to worry about masking in the comparison. This will be used to simplify a comparison in the following patch.

This patch simplifies the process of finding a free segment table entry by disabling the secondary hash. This reduces the number of possible entries in the segment table for a given address from 16 to 8. Due to the large segment sizes we use it is extremely unlikely that the secondary hash would ever have been used in practice, so this should not have any negative impacts and may even improve performance due to the reduced number of comparisons that software & hardware need to perform. This patch clears the SC bit in the hardware's state register (CXL_PSL_SR_An) to disable the secondary hash in the hardware since we can no longer fill out entries using it.

Commit 78b81f46 ("ARM: dts: imx28-evk: Run I2C0 at 400kHz") caused issues when doing the following sequence in loop: - Boot the kernel - Perform audio playback - Reboot the system via 'reboot' command In many times the audio card cannot be probed, which causes playback to fail. After restoring to the original i2c0 frequency of 100kHz there is no such problem anymore. This reverts commit 78b81f46.

Fix a typo error, the "emi" names refer to the eim clocks. The change fixes typo in EIM and EIM_SLOW pre-output dividers and selectors clock names. Notably EIM_SLOW clock itself is named correctly.

When modifying code, ftrace has several checks to make sure things are being done correctly. One of them is to make sure any code it modifies is exactly what it expects it to be before it modifies it. In order to do so with the new trampoline logic, it must be able to find out what trampoline a function is hooked to in order to see if the code that hooks to it is what's expected. The logic to find the trampoline from a record (accounting descriptor for a function that is hooked) needs to only look at the "old_hash" of an ops that is being modified. The old_hash is the list of function an ops is hooked to before its update. Since a record would only be pointing to an ops that is being modified if it was already hooked before. Currently, it can pick a modified ops based on its new functions it will be hooked to, and this picks the wrong trampoline and causes the check to fail, disabling ftrace.

The code that checks for trampolines when modifying function hooks tests against a modified ops "old_hash". But the ops old_hash pointer is not being updated before the changes are made, making it possible to not find the right hash to the callback and possibly causing ftrace to break in accounting and disable itself. Have the ops set its old_hash before the modifying takes place. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>

Pull two sparc fixes from David Miller: 1) Fix boots with gcc-4.9 compiled sparc64 kernels. 2) Add missing __get_user_pages_fast() on sparc64 to fix hangs on futexes used in transparent hugepage areas. It's really idiotic to have a weak symbolled fallback that just returns zero, and causes this kind of bug. There should be no backup implementation and the link should fail if the architecture fails to provide __get_user_pages_fast() and supports transparent hugepages. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc: sparc64: Implement __get_user_pages_fast(). sparc64: Fix register corruption in top-most kernel stack frame during boot.
