Pull x86 cache allocation interface from Thomas Gleixner: "This provides support for Intel's Cache Allocation Technology, a cache partitioning mechanism. The interface is odd, but the hardware interface of that CAT stuff is odd as well. We tried hard to come up with an abstraction, but that only allows rather simple partitioning, but no way of sharing and dealing with the per package nature of this mechanism. In the end we decided to expose the allocation bitmaps directly so all combinations of the hardware can be utilized. There are two ways of associating a cache partition: - Task A task can be added to a resource group. It uses the cache partition associated to the group. - CPU All tasks which are not member of a resource group use the group to which the CPU they are running on is associated with. That allows for simple CPU based partitioning schemes. The main expected user sare: - Virtualization so a VM can only trash only the associated part of the cash w/o disturbing others - Real-Time systems to seperate RT and general workloads. - Latency sensitive enterprise workloads - In theory this also can be used to protect against cache side channel attacks" [ Intel RDT is "Resource Director Technology". The interface really is rather odd and very specific, which delayed this pull request while I was thinking about it. The pull request itself came in early during the merge window, I just delayed it until things had calmed down and I had more time. But people tell me they'll use this, and the good news is that it is _so_ specific that it's rather independent of anything else, and no user is going to depend on the interface since it's pretty rare. So if push comes to shove, we can just remove the interface and nothing will break ] * 'x86-cache-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (31 commits) x86/intel_rdt: Implement show_options() for resctrlfs x86/intel_rdt: Call intel_rdt_sched_in() with preemption disabled x86/intel_rdt: Update task closid immediately on CPU in rmdir and unmount x86/intel_rdt: Fix setting of closid when adding CPUs to a group x86/intel_rdt: Update percpu closid immeditately on CPUs affected by changee x86/intel_rdt: Reset per cpu closids on unmount x86/intel_rdt: Select KERNFS when enabling INTEL_RDT_A x86/intel_rdt: Prevent deadlock against hotplug lock x86/intel_rdt: Protect info directory from removal x86/intel_rdt: Add info files to Documentation x86/intel_rdt: Export the minimum number of set mask bits in sysfs x86/intel_rdt: Propagate error in rdt_mount() properly x86/intel_rdt: Add a missing #include MAINTAINERS: Add maintainer for Intel RDT resource allocation x86/intel_rdt: Add scheduler hook x86/intel_rdt: Add schemata file x86/intel_rdt: Add tasks files x86/intel_rdt: Add cpus file x86/intel_rdt: Add mkdir to resctrl file system x86/intel_rdt: Add "info" files to resctrl file system ...

This reverts commit 16200948. The commit was intended to cover the race condition, but it introduced yet another regression for devices with the implicit feedback, leading to a kernel panic due to NULL-dereference in an irq context. As the race condition that was addressed by the commit is very rare and the regression is much worse, let's revert the commit for rc1, and fix the issue properly in a later patch.

Commit 3322d0d6 ("selinux: keep SELinux in sync with new capability definitions") added a check on the defined capabilities without explicitly including the capability header file which caused problems when building genheaders for users of clang/llvm. Resolve this by using the kernel headers when building genheaders, which is arguably the right thing to do regardless, and explicitly including the kernel's capability.h header file in classmap.h. We also update the mdp build, even though it wasn't causing an error we really should be using the headers from the kernel we are building. Reported-by:

The mmc_read_ssr() function results in DMA to the raw_ssr member of struct mmc_card, which is not guaranteed to be cache line aligned & thus might not meet the requirements set out in Documentation/DMA-API.txt: Warnings: Memory coherency operates at a granularity called the cache line width. In order for memory mapped by this API to operate correctly, the mapped region must begin exactly on a cache line boundary and end exactly on one (to prevent two separately mapped regions from sharing a single cache line). Since the cache line size may not be known at compile time, the API will not enforce this requirement. Therefore, it is recommended that driver writers who don't take special care to determine the cache line size at run time only map virtual regions that begin and end on page boundaries (which are guaranteed also to be cache line boundaries). On some systems where DMA is non-coherent this can lead to us losing data that shares cache lines with the raw_ssr array. Fix this by kmalloc'ing a temporary buffer to perform DMA into. kmalloc will ensure the buffer is suitably aligned, allowing the DMA to be performed without any loss of data. Signed-off-by:

Since CPU hotplug callbacks are requested for CPUHP_AP_ONLINE_DYN state, successful callback initialization will result in cpuhp_setup_state() returning a positive value. Therefore acpi_cpufreq_online being zero indicates that callbacks have not been installed. This means that acpi_cpufreq_boost_exit() should only remove them if acpi_cpufreq_online is positive. Trying to call cpuhp_remove_state_nocalls(0) will cause a BUG(). Signed-off-by:

This patch removes the users of the deprectated APIs: acpi_get_table_with_size() early_acpi_os_unmap_memory() The following APIs should be used instead of: acpi_get_table() acpi_put_table() The deprecated APIs are invented to be a replacement of acpi_get_table() during the early stage so that the early mapped pointer will not be stored in ACPICA core and thus the late stage acpi_get_table() won't return a wrong pointer. The mapping size is returned just because it is required by early_acpi_os_unmap_memory() to unmap the pointer during early stage. But as the mapping size equals to the acpi_table_header.length (see acpi_tb_init_table_descriptor() and acpi_tb_validate_table()), when such a convenient result is returned, driver code will start to use it instead of accessing acpi_table_header to obtain the length. Thus this patch cleans up the drivers by replacing returned table size with acpi_table_header.length, and should be a no-op. Reported-by:

ACPICA: Tables: Back port acpi_get_table_with_size() and early_acpi_os_unmap_memory() from Linux kernel ACPICA commit cac6790954d4d752a083e6122220b8a22febcd07 This patch back ports Linux acpi_get_table_with_size() and early_acpi_os_unmap_memory() into ACPICA upstream to reduce divergences. The 2 APIs are used by Linux as table management APIs for long time, it contains a hidden logic that during the early stage, the mapped tables should be unmapped before the early stage ends. During the early stage, tables are handled by the following sequence: acpi_get_table_with_size(); parse the table early_acpi_os_unmap_memory(); During the late stage, tables are handled by the following sequence: acpi_get_table(); parse the table Linux uses acpi_gbl_permanent_mmap to distinguish the early stage and the late stage. The reasoning of introducing acpi_get_table_with_size() is: ACPICA will remember the early mapped pointer in acpi_get_table() and Linux isn't able to prevent ACPICA from using the wrong early mapped pointer during the late stage as there is no API provided from ACPICA to be an inverse of acpi_get_table() to forget the early mapped pointer. But how ACPICA can work with the early/late stage requirement? Inside of ACPICA, tables are ensured to be remained in "INSTALLED" state during the early stage, and they are carefully not transitioned to "VALIDATED" state until the late stage. So the same logic is in fact implemented inside of ACPICA in a different way. The gap is only that the feature is not provided to the OSPMs in an accessible external API style. It then is possible to fix the gap by providing an inverse of acpi_get_table() from ACPICA, so that the two Linux sequences can be combined: acpi_get_table(); parse the table acpi_put_table(); In order to work easier with the current Linux code, acpi_get_table() and acpi_put_table() is implemented in a usage counting based style: 1. When the usage count of the table is increased from 0 to 1, table is mapped and .Pointer is set with the mapping address (VALIDATED); 2. When the usage count of the table is decreased from 1 to 0, .Pointer is unset and the mapping address is unmapped (INVALIDATED). So that we can deploy the new APIs to Linux with minimal effort by just invoking acpi_get_table() in acpi_get_table_with_size() and invoking acpi_put_table() in early_acpi_os_unmap_memory().

Restructure the timer interrupt function to better cope with missed timer irqs. Optimize the calculation when the next interrupt should happen and skip irqs if they would happen too shortly after exit of the irq function. The update_process_times() call is done anyway at every timer irq, so we can safely drop the prof_counter and prof_multiplier variables from the per_cpu structure. Signed-off-by:

Xin Long says: ==================== sctp: fix the issue that may copy duplicate addrs into assoc's bind address list Patch 1/2 is to fix some indent level. Given that we have kernels out there with this issue, patch 2/2 also fix sctp_raw_to_bind_addrs. v1 -> v2: Explain why we didn't filter the duplicate addresses when global address list gets updated in patch 2/2 changelog. ==================== Signed-off-by:

sctp.local_addr_list is a global address list that is supposed to include all the local addresses. sctp updates this list according to NETDEV_UP/ NETDEV_DOWN notifications. However, if multiple NICs have the same address, the global list would have duplicate addresses. Even if for one NIC, promote secondaries in __inet_del_ifa can also lead to accumulating duplicate addresses. When sctp binds address 'ANY' and creates a connection, it copies all the addresses from global list into asoc's bind addr list, which makes sctp pack the duplicate addresses into INIT/INIT_ACK packets. This patch is to filter the duplicate addresses when copying the addrs from global list in sctp_copy_local_addr_list and unpacking addr_param from cookie in sctp_raw_to_bind_addrs to asoc's bind addr list. Note that we can't filter the duplicate addrs when global address list gets updated, As NETDEV_DOWN event may remove an addr that still exists in another NIC. Signed-off-by:

This patch is to reduce indent level by using continue when the addr is not allowed, and also drop end_copy by using break. Signed-off-by:

Dongpo Li says: ==================== net: hix5hd2_gmac: keep the compatible string not changed This patch series fix the patch: d0fb6ba7 ("net: hix5hd2_gmac: add generic compatible string") The SoC hix5hd2 compatible string has the suffix "-gmac" and we should not change its compatible string. So we should name all the compatible string with the suffix "-gmac". Creating a new name suffix "-gemac" is unnecessary. ==================== Signed-off-by:
