2017-08-16x86: Fix norandmaps/ADDR_NO_RANDOMIZEOleg Nesterov
Documentation/admin-guide/kernel-parameters.txt says: norandmaps Don't use address space randomization. Equivalent to echo 0 > /proc/sys/kernel/randomize_va_space but it doesn't work because arch_rnd() which is used to randomize mm->mmap_base returns a random value unconditionally. And as Kirill pointed out, ADDR_NO_RANDOMIZE is broken by the same reason. Just shift the PF_RANDOMIZE check from arch_mmap_rnd() to arch_rnd().

2017-08-16sparc64: remove unnecessary log messageTushar Dave
There is no need to log message if ATU hvapi couldn't get register. Unlike PCI hvapi, ATU hvapi registration failure is not hard error. Even if ATU hvapi registration fails (on system with ATU or without ATU) system continues with legacy IOMMU. So only log message when ATU hvapi successfully get registered.

2017-08-16x86/intel_rdt/cqm: Improve limbo list processingVikas Shivappa
During a mkdir, the entire limbo list is synchronously checked on each package for free RMIDs by sending IPIs. With a large number of RMIDs (SKL has 192) this creates a intolerable amount of work in IPIs. Replace the IPI based checking of the limbo list with asynchronous worker threads on each package which periodically scan the limbo list and move the RMIDs that have: llc_occupancy < threshold_occupancy on all packages to the free list. mkdir now returns -ENOSPC if the free list and the limbo list ere empty or returns -EBUSY if there are RMIDs on the limbo list and the free list is empty. Getting rid of the IPIs also simplifies the data structures and the serialization required for handling the lists.

2017-08-16x86/intel_rdt/mbm: Fix MBM overflow handler during CPU hotplugVikas Shivappa
When a CPU is dying, the overflow worker is canceled and rescheduled on a different CPU in the same domain. But if the timer is already about to expire this essentially doubles the interval which might result in a non detected overflow. Cancel the overflow worker and reschedule it immediately on a different CPU in same domain. The work could be flushed as well, but that would reschedule it on the same CPU.

2017-08-16powerpc: Fix VSX enabling/flushing to also test MSR_FP and MSR_VECBenjamin Herrenschmidt
VSX uses a combination of the old vector registers, the old FP registers and new "second halves" of the FP registers. Thus when we need to see the VSX state in the thread struct (flush_vsx_to_thread()) or when we'll use the VSX in the kernel (enable_kernel_vsx()) we need to ensure they are all flushed into the thread struct if either of them is individually enabled. Unfortunately we only tested if the whole VSX was enabled, not if they were individually enabled.

In addition to the WFI idle state which is the default shallowest state for all ARM cpus, the Hi3660 supports the following states: - CA53 CPUs: - CPU_SLEEP: CPU power off state - CLUSTER_SLEEP_0: Cluster power off state - CA73 CPUs: - CPU_NAP: CPU retention state - CPU_SLEEP: CPU power off state - CLUSTER_SLEEP_1: Cluster power off state This patch adds the idle states description for the Hi3660 to the device tree.

2017-08-16arm64: dts: hi6220: improve g-tx-fifo-size setting for usb deviceShawn Guo
The current usb device g-tx-fifo-size setting in DT causes two problems for kernel driver. 1. On hi6220, there are 15 tx_fifo dedicated for all EPs except EP0, while DT only provides tx_fifo settings for 6 EPs. It results in the following annoying complaints from kernel. [ 4.451623] dwc2 f72c0000.usb: dwc2_check_param_tx_fifo_sizes: Invalid parameter g_tx_fifo_size[7]=0 [ 4.461303] dwc2 f72c0000.usb: dwc2_check_param_tx_fifo_sizes: Invalid parameter g_tx_fifo_size[8]=0 [ 4.470969] dwc2 f72c0000.usb: dwc2_check_param_tx_fifo_sizes: Invalid parameter g_tx_fifo_size[9]=0 [ 4.480632] dwc2 f72c0000.usb: dwc2_check_param_tx_fifo_sizes: Invalid parameter g_tx_fifo_size[10]=0 [ 4.490385] dwc2 f72c0000.usb: dwc2_check_param_tx_fifo_sizes: Invalid parameter g_tx_fifo_size[11]=0 [ 4.500140] dwc2 f72c0000.usb: dwc2_check_param_tx_fifo_sizes: Invalid parameter g_tx_fifo_size[12]=0 [ 4.509892] dwc2 f72c0000.usb: dwc2_check_param_tx_fifo_sizes: Invalid parameter g_tx_fifo_size[13]=0 [ 4.519646] dwc2 f72c0000.usb: dwc2_check_param_tx_fifo_sizes: Invalid parameter g_tx_fifo_size[14]=0 [ 4.529399] dwc2 f72c0000.usb: dwc2_check_param_tx_fifo_sizes: Invalid parameter g_tx_fifo_size[15]=0 [ 4.539244] dwc2 f72c0000.usb: EPs: 16, dedicated fifos, 1920 entries in SPRAM Besides of that, the total 1920 fifo entries isn't fully utilized. Endpoint Info Control block consumes 128 entries, g-rx-fifo-size is 512, and g-np-tx-fifo-size is 128. So the fifi entries available for tx_fifo is: 1920 - 128 - 512 - 128 = 1152. Considering that the minimal valid tx_fifo size for each EP is 16, it should be reasonable to allocate 1152 entries as: 128 x 8 + 16 x 7 = 1136 (only 16 entries unused). With this new setting, we can get more EPs to use while removing the above warning messages in the meantime. 2. Another consequence of above invalid g_tx_fifo_size parameter is that kernel driver will use values read from hardware register as the fall-back. The value is 2048 for each EP fifo. That's obviously invalid either, because even fifo entries for one EP exceeds the total entries 1920. That's why we see the following fat warning from function dwc2_hsotg_init_fifo(). The new g-tx-fifo-size settings help to remove the warning as well.

2017-08-16powerpc/mm/hugetlb: Allow runtime allocation of 16G.Aneesh Kumar K.V
Now that we have GIGANTIC_PAGE enabled on powerpc, use this for 16G hugepages with hash translation mode. Depending on the total system memory we have, we may be able to allocate 16G hugepages runtime. This also remove the hugetlb setup difference between hash/radix translation mode.

2017-08-16powerpc/mm/hugetlb: Add support for reserving gigantic huge pages via kernel ↵Aneesh Kumar K.V
command line With commit aa888a74977a8 ("hugetlb: support larger than MAX_ORDER") we added support for allocating gigantic hugepages via kernel command line. Switch ppc64 arch specific code to use that. W.r.t FSL support, we now limit our allocation range using BOOTMEM_ALLOC_ACCESSIBLE. We use the kernel command line to do reservation of hugetlb pages on powernv platforms. On pseries hash mmu mode the supported gigantic huge page size is 16GB and that can only be allocated with hypervisor assist. For pseries the command line option doesn't do the allocation. Instead pseries does gigantic hugepage allocation based on hypervisor hint that is specified via "ibm,expected#pages" property of the memory node.
