* arm64: KVM: Sanitize PSTATE.M when being set from userspaceMarc Zyngier2018-10-011-1/+9
| | | | | | | | | | | | | | | Not all execution modes are valid for a guest, and some of them depend on what the HW actually supports. Let's verify that what userspace provides is compatible with both the VM settings and the HW capabilities.

* arm64: KVM: Tighten guest core register access from userspaceDave Martin2018-10-011-0/+45
| | | | | | | | | | | | | | | | | | | We currently allow userspace to access the core register file in about any possible way, including straddling multiple registers and doing unaligned accesses. This is not the expected use of the ABI, and nobody is actually using it that way. Let's tighten it by explicitly checking the size and alignment for each field of the register file.

* arm64: hugetlb: Avoid unnecessary clearing in huge_ptep_set_access_flagsSteve Capper2018-09-241-4/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For contiguous hugetlb, huge_ptep_set_access_flags performs a get_clear_flush (which then flushes the TLBs) even when no change of ptes is necessary. Unfortunately, this behaviour can lead to back-to-back page faults being generated when running with multiple threads that access the same contiguous huge page. Thread 1 | Thread 2 -----------------------------+------------------------------ hugetlb_fault | huge_ptep_set_access_flags | -> invalidate pte range | hugetlb_fault continue processing | wait for hugetlb_fault_mutex release mutex and return | huge_ptep_set_access_flags | -> invalidate pte range hugetlb_fault ... This patch changes huge_ptep_set_access_flags s.t. we first read the contiguous range of ptes (whilst preserving dirty information); the pte range is only then invalidated where necessary and this prevents further spurious page faults.

* arm64: hugetlb: Fix handling of young ptesSteve Capper2018-09-241-3/+9
| | | | | | | | | | | | | | | In the contiguous bit hugetlb break-before-make code we assume that all hugetlb pages are young. In fact, remove_migration_pte is able to place an old hugetlb pte so this assumption is not valid. This patch fixes the contiguous hugetlb scanning code to preserve young ptes.

* arm64: kernel: arch_crash_save_vmcoreinfo() should depend on CONFIG_CRASH_COREJames Morse2018-09-113-11/+20
| | | | | | | | | | | | | | | | | | | Since commit 23c85094fe18 ("proc/kcore: add vmcoreinfo note to /proc/kcore") the kernel has exported the vmcoreinfo PT_NOTE on /proc/kcore as well as /proc/vmcore. arm64 only exposes it's additional arch information via arch_crash_save_vmcoreinfo() if built with CONFIG_KEXEC, as kdump was previously the only user of vmcoreinfo. Move this weak function to a separate file that is built at the same time as its caller in kernel/crash_core.c. This ensures values like 'kimage_voffset' are always present in the vmcoreinfo PT_NOTE.

This problem doesn't just apply to NUMA systems. If the architecture doesn't set HAVE_ARCH_PFN_VALID, pfn_valid() will return true if the pfn is part of a valid sparsemem section. When working with multiple pages, the mm code uses pfn_valid_within() to test each page it uses within the sparsemem section is valid. On most systems memory comes in MAX_ORDER_NR_PAGES chunks which all have valid/initialised struct pages. In this case pfn_valid_within() is optimised out. Systems where this isn't true (e.g. due to nomap) should set HOLES_IN_ZONE and provide HAVE_ARCH_PFN_VALID so that mm tests each page as it works with it. Currently non-NUMA arm64 systems can't enable HOLES_IN_ZONE, leading to a VM_BUG_ON(): | page:fffffdff802e1780 is uninitialized and poisoned | raw: ffffffffffffffff ffffffffffffffff ffffffffffffffff ffffffffffffffff | raw: ffffffffffffffff ffffffffffffffff ffffffffffffffff ffffffffffffffff | page dumped because: VM_BUG_ON_PAGE(PagePoisoned(p)) | ------------[ cut here ]------------ | kernel BUG at include/linux/mm.h:978! | Internal error: Oops - BUG: 0 [#1] PREEMPT SMP [...] | CPU: 1 PID: 25236 Comm: dd Not tainted 4.18.0 #7 | Hardware name: QEMU KVM Virtual Machine, BIOS 0.0.0 02/06/2015 | pstate: 40000085 (nZcv daIf -PAN -UAO) | pc : move_freepages_block+0x144/0x248 | lr : move_freepages_block+0x144/0x248 | sp : fffffe0071177680 [...] | Process dd (pid: 25236, stack limit = 0x0000000094cc07fb) | Call trace: | move_freepages_block+0x144/0x248 | steal_suitable_fallback+0x100/0x16c | get_page_from_freelist+0x440/0xb20 | __alloc_pages_nodemask+0xe8/0x838 | new_slab+0xd4/0x418 | ___slab_alloc.constprop.27+0x380/0x4a8 | __slab_alloc.isra.21.constprop.26+0x24/0x34 | kmem_cache_alloc+0xa8/0x180 | alloc_buffer_head+0x1c/0x90 | alloc_page_buffers+0x68/0xb0 | create_empty_buffers+0x20/0x1ec | create_page_buffers+0xb0/0xf0 | __block_write_begin_int+0xc4/0x564 | __block_write_begin+0x10/0x18 | block_write_begin+0x48/0xd0 | blkdev_write_begin+0x28/0x30 | generic_perform_write+0x98/0x16c | __generic_file_write_iter+0x138/0x168 | blkdev_write_iter+0x80/0xf0 | __vfs_write+0xe4/0x10c | vfs_write+0xb4/0x168 | ksys_write+0x44/0x88 | sys_write+0xc/0x14 | el0_svc_naked+0x30/0x34 | Code: aa1303e0 90001a01 91296421 94008902 (d4210000) | ---[ end trace 1601ba47f6e883fe ]--- Remove the NUMA dependency.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 71e52c278c54 ("crypto: arm64/aes-ce-gcm - operate on two input blocks at a time") modified the granularity at which the AES/GCM code processes its input to allow subsequent changes to be applied that improve performance by using aggregation to process multiple input blocks at once. For this reason, it doubled the algorithm's 'chunksize' property to 2 x AES_BLOCK_SIZE, but retained the non-SIMD fallback path that processes a single block at a time. In some cases, this violates the skcipher scatterwalk API, by calling skcipher_walk_done() with a non-zero residue value for a chunk that is expected to be handled in its entirety. This results in a WARN_ON() to be hit by the TLS self test code, but is likely to break other user cases as well. Unfortunately, none of the current test cases exercises this exact code path at the moment. Fixes: 71e52c278c54 ("crypto: arm64/aes-ce-gcm - operate on two ...")

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A number of the Rockchip-specific drivers (IOMMU, display controllers) are now assuming that CONFIG_PM is set, and may completely misbehave if that's not the case. Since there is hardly any reason for this configuration option not to be selected anyway, let's require it (in the same way Tegra already does).

Fix the cpu-capacity.txt documentation that uses the incorrect value so we don't get copy-paste errors like these. Clarify the language in idle-states.txt by removing the reference to the psci bindings that might be causing this confusion. Finally, fix devicetrees of various boards to reflect current documentation.

Commit 06c5040cdb13 ("kbuild: enable 'make CPPFLAGS=...' to add additional options to CPP") renamed CPPFLAGS to KBUILD_CPPFLAGS. For some reason, LDFLAGS was not renamed. Using a well-known variable like LDFLAGS may result in accidental override of the variable. Kbuild generally uses KBUILD_ prefixed variables for the internally appended options, so here is one more conversion to sanitize the naming convention.

This was required to deal with different address offsets for the TM and SROT registers across different SoC families. 8996 has two TSENS IP blocks, initialise the second one too. Since tsens-common.c/init_common() currently only registers one address space, the order is important (TM before SROT). This is OK since the code doesn't really use the SROT functionality yet.
