The default dma_common_get_sgtable() implementation relies on the CPU address of the buffer being a regular lowmem address. This is not always the case on arm64, since allocations from the various DMA pools may have remapped vmalloc addresses, rendering the use of virt_to_page() invalid. Fix this by providing our own implementation based on the fact that we can safely derive a physical address from the DMA address in both cases.

Nobody seems to be producing !SMP systems anymore, so this is just becoming a source of kernel bugs, particularly if people want to use coherent DMA with non-shared pages. This patch forces CONFIG_SMP=y for arm64, removing a modest amount of code in the process. Signed-off-by: NWill Deacon <will.deacon@arm.com>

We currently bundle the callchain handling code with the PMU code, despite the fact the two are distinct, and the former can be useful even in the absence of the latter. Follow the example of arch/arm and factor the callchain handling into its own file dependent on CONFIG_PERF_EVENTS rather than CONFIG_HW_PERF_EVENTS.

The compat ptrace interface allows access to the TLS register, hardware breakpoints and watchpoints, syscall number. However, a native task using the native ptrace interface to debug compat tasks (e.g. multi-arch gdb) only has access to the general and VFP register sets. The compat ptrace interface cannot be accessed from a native task. This patch adds a new user_aarch32_ptrace_view which contains the TLS, hardware breakpoint/watchpoint and syscall number regsets in addition to the existing GPR and VFP regsets. This view is backwards compatible with the previous kernels. Core dumping of 32-bit tasks and compat ptrace are not affected since the original user_aarch32_view is preserved.

Plumb up Makefile arguments for the already supported formats in the kbuild system: lz4, bzip2, lzma, and lzo. Note that just as with Image.gz, these images are not self-decompressing and the booting firmware still needs to handle decompression before launching the kernel image.

The ARMv8.1 architecture extensions introduce support for hardware updates of the access and dirty information in page table entries. With TCR_EL1.HA enabled, when the CPU accesses an address with the PTE_AF bit cleared in the page table, instead of raising an access flag fault the CPU sets the actual page table entry bit. To ensure that kernel modifications to the page tables do not inadvertently revert a change introduced by hardware updates, the exclusive monitor (ldxr/stxr) is adopted in the pte accessors. When TCR_EL1.HD is enabled, a write access to a memory location with the DBM (Dirty Bit Management) bit set in the corresponding pte automatically clears the read-only bit (AP[2]). Such DBM bit maps onto the Linux PTE_WRITE bit and to check whether a writable (DBM set) page is dirty, the kernel tests the PTE_RDONLY bit. In order to allow read-only and dirty pages, the kernel needs to preserve the software dirty bit. The hardware dirty status is transferred to the software dirty bit in ptep_set_wrprotect() (using load/store exclusive loop) and pte_modify().

arch_find_n_match_cpu_physical_id parses the device tree to get the device node for a given logical cpu index. However, since ARM PMUs get probed after the CPU device nodes are stashed while registering the cpus, we can use of_cpu_device_node_get to avoid another DT parse. This patch replaces arch_find_n_match_cpu_physical_id with of_cpu_device_node_get to reuse the stashed value directly instead.

Toshi explains: "No, the default values need to be set to the fallback types, i.e. minimal supported mode. For WC and WT, UC is the fallback type. When PAT is disabled, pat_init() does update the tables below to enable WT per the default BIOS setup. However, when PAT is enabled, but CPU has PAT -errata, WT falls back to UC per the default values."

A new BLK namespace "seed" device is created whenever the current seed is successfully probed. However, if that namespace is assigned to a BTT it may never directly experience a successful probe as it is a subordinate device to a BTT configuration. The effect of the current code is that no new namespaces can be instantiated, after the seed namespace, to consume available BLK DPA capacity. Fix this by treating a successful BTT probe event as a successful probe event for the backing namespace.
