The common cros-ec keymap has been defined as macros. This patch uses the macros to simply linux,keymap in cros-ec-keyboard.dtsi file. This patch also creates an alias for keyboard-controller to make it easier to override the keymap in board-specific dts later.

2021-02-23riscv: Improve kasan population by using hugepages when possibleAlexandre Ghiti1-0/+24
The kasan functions that populates the shadow regions used to allocate them page by page and did not take advantage of hugepages, so fix this by trying to allocate hugepages of 1GB and fallback to 2MB hugepages or 4K pages in case it fails. This reduces the page table memory consumption and improves TLB usage, as shown below: Before this patch: ---[ Kasan shadow start ]--- 0xffffffc000000000-0xffffffc400000000 0x00000000818ef000 16G PTE .

2021-02-23riscv: Improve kasan population functionAlexandre Ghiti1-28/+63
Current population code populates a whole page table without taking care of what could have been already allocated and without taking into account possible index in page table, assuming the virtual address to map is always aligned on the page table size, which, for example, won't be the case when the kernel will get pushed to the end of the address space. Address those problems by rewriting the kasan population function, splitting it into subfunctions for each different page table level.

2021-02-23riscv: Get rid of MAX_EARLY_MAPPING_SIZEAlexandre Ghiti1-16/+5
At early boot stage, we have a whole PGDIR to map the kernel, so there is no need to restrict the early mapping size to 128MB. Removing this define also allows us to simplify some compile time logic. This fixes large kernel mappings with a size greater than 128MB, as it is the case for syzbot kernels whose size was just ~130MB. Note that on rv64, for now, we are then limited to PGDIR size for early mapping as we can't use PGD mappings (see [1]). That should be enough given the relative small size of syzbot kernels compared to PGDIR_SIZE which is 1GB.

2021-02-23riscv: Disable KSAN_SANITIZE for vDSOTobias Klauser1-1/+2
We use the generic C VDSO implementations of a handful of clock-related functions. When kasan is enabled this results in asan stub calls that are unlikely to be resolved by userspace, this just disables KASAN when building the VDSO.

2021-02-23riscv: Add Canaan Kendryte K210 SD card defconfigDamien Le Moal1-0/+92
The nommu_k210_defconfig default configuration allows booting a Canaan Kendryte K210 SoC based boards using an embedded intramfs cpio file. Modifying this configuration to enable support for the board SD card is not trivial for all users. To help beginners getting started with these boards, add the nommu_k210_sdcard_defconfig default configuration file to set all configuration options necessary to use the board mmc-spi sd card for the root file system. This new configuration adds support for the block layer, the mmc-spi driver and modifies the boot options to specify the rootfs device as mmcblk0p1 (first partition of the sd card block device). The ext2 file system is selected by default to encourage its use as that results in only about 4KB added to the kernel image size. As ext2 does not have journaling, the boot options specify a read-only mount of the file system. Similarly to the smaller nommu_k210_defconfig, this new default configuration disables virtual terminal support to reduce the kernel image size. The default device tree selected is unchanged, specifying the simple "k210_generic" device tree file. The user must change this setting to specify the device tree suitable for the board being used (sipeed_maix_bit, sipeed_maix_dock, sipeed_maix_go, sipeed_maixduino or canaan_kd233).

Update the Kendryte k210 nommu default configuration file (nommu_k210_defconfig) to include device drivers for reset, reboot, I2C, SPI, gpio and LEDs support. Virtual Terminal support is also disabled as no terminal devices are supported and enabled. Disabling CONFIG_VT (removing the no longer needed override for CONFIG_VGA_CONSOLE) reduces the kernel image size by about 65 KB. This default configuration remains suitable for a system using an initramfs cpio file linked into the kernel image.

2021-02-23riscv: Update Canaan Kendryte K210 device treeDamien Le Moal4-52/+414
Update the Canaan Kendryte K210 base device tree k210.dtsi to define all supported peripherals of the SoC, their clocks and reset lines. The device tree file k210.dts is renamed to k210_generic.dts and becomes the default value selection of the configuration option SOC_CANAAN_K210_DTB_BUILTIN_SOURCE. No device beside the serial console is defined by this device tree. This makes this generic device tree suitable for use with a builtin initramfs with all known K210 based boards. These changes result in the K210_CLK_ACLK clock ID to be unused and removed from the dt-bindings k210-clk.h header file. Most updates to the k210.dtsi file come from Sean Anderson's work on U-Boot support for the K210.

2021-02-22KVM: x86/mmu: Consider the hva in mmu_notifier retryDavid Stevens4-11/+30
Track the range being invalidated by mmu_notifier and skip page fault retries if the fault address is not affected by the in-progress invalidation. Handle concurrent invalidations by finding the minimal range which includes all ranges being invalidated. Although the combined range may include unrelated addresses and cannot be shrunk as individual invalidation operations complete, it is unlikely the marginal gains of proper range tracking are worth the additional complexity. The primary benefit of this change is the reduction in the likelihood of extreme latency when handing a page fault due to another thread having been preempted while modifying host virtual addresses.

Don't retry a page fault due to an mmu_notifier invalidation when handling a page fault for a GPA that did not resolve to a memslot, i.e. an MMIO page fault. Invalidations from the mmu_notifier signal a change in a host virtual address (HVA) mapping; without a memslot, there is no HVA and thus no possibility that the invalidation is relevant to the page fault being handled. Note, the MMIO vs. memslot generation checks handle the case where a pending memslot will create a memslot overlapping the faulting GPA. The mmu_notifier checks are orthogonal to memslot updates.

2021-02-22KVM: nSVM: prepare guest save area while is_guest_mode is truePaolo Bonzini1-1/+1
Right now, enter_svm_guest_mode is calling nested_prepare_vmcb_save and nested_prepare_vmcb_control. This results in is_guest_mode being false until the end of nested_prepare_vmcb_control. This is a problem because nested_prepare_vmcb_save can in turn cause changes to the intercepts and these have to be applied to the "host VMCB" (stored in svm->nested.hsave) and then merged with the VMCB12 intercepts into svm->vmcb. In particular, without this change we forget to set the CR0 read and CR0 write intercepts when running a real mode L2 guest with NPT disabled. The guest is therefore able to see the CR0.PG bit that KVM sets to enable "paged real mode". This patch fixes the svm.flat mode_switch test case with npt=0. There are no other problematic calls in nested_prepare_vmcb_save. Moving is_guest_mode to the end is done since commit 06fc7772690d ("KVM: SVM: Activate nested state only when guest state is complete", 2010-04-25). However, back then KVM didn't grab a different VMCB when updating the intercepts, it had already copied/merged L1's stuff to L0's VMCB, and then updated L0's VMCB regardless of is_nested(). Later recalc_intercepts was introduced in commit 384c63684397 ("KVM: SVM: Add function to recalculate intercept masks", 2011-01-12). This introduced the bug, because recalc_intercepts now throws away the intercept manipulations that svm_set_cr0 had done in the meanwhile to svm->vmcb.

2021-02-22bpf, x86: Fix BPF_FETCH atomic and/or/xor with r0 as srcBrendan Jackman1-3/+7
This code generates a CMPXCHG loop in order to implement atomic_fetch bitwise operations. Because CMPXCHG is hard-coded to use rax (which holds the BPF r0 value), it saves the _real_ r0 value into the internal "ax" temporary register and restores it once the loop is complete. In the middle of the loop, the actual bitwise operation is performed using src_reg. The bug occurs when src_reg is r0: as described above, r0 has been clobbered and the real r0 value is in the ax register. Therefore, perform this operation on the ax register instead, when src_reg is r0.

I hope to switch the default MMU around 5.12-rc3 (some testing was delayed due to Chinese New Year). - Cleanups for MAXPHYADDR checks - Use static calls for vendor-specific callbacks - On AMD, use VMLOAD/VMSAVE to save and restore host state - Stop using deprecated jump label APIs - Workaround for AMD erratum that made nested virtualization unreliable - Support for LBR emulation in the guest - Support for communicating bus lock vmexits to userspace - Add support for SEV attestation command - Miscellaneous cleanups PPC: - Support for second data watchpoint on POWER10 - Remove some complex workarounds for buggy early versions of POWER9 - Guest entry/exit fixes ARM64: - Make the nVHE EL2 object relocatable - Cleanups for concurrent translation faults hitting the same page - Support for the standard TRNG hypervisor call - A bunch of small PMU/Debug fixes - Simplification of the early init hypercall handling Non-KVM changes (with acks): - Detection of contended rwlocks (implemented only for qrwlocks, because KVM only needs it for x86) - Allow __DISABLE_EXPORTS from assembly code - Provide a saner follow_pfn replacements for modules" * tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm: (192 commits) KVM: x86/xen: Explicitly pad struct compat_vcpu_info to 64 bytes KVM: selftests: Don't bother mapping GVA for Xen shinfo test KVM: selftests: Fix hex vs. decimal snafu in Xen test KVM: selftests: Fix size of memslots created by Xen tests KVM: selftests: Ignore recently added Xen tests' build output KVM: selftests: Add missing header file needed by xAPIC IPI tests KVM: selftests: Add operand to vmsave/vmload/vmrun in svm.c KVM: SVM: Make symbol 'svm_gp_erratum_intercept' static locking/arch: Move qrwlock.h include after qspinlock.h KVM: PPC: Book3S HV: Fix host radix SLB optimisation with hash guests KVM: PPC: Book3S HV: Ensure radix guest has no SLB entries KVM: PPC: Don't always report hash MMU capability for P9 < DD2.2 KVM: PPC: Book3S HV: Save and restore FSCR in the P9 path KVM: PPC: remove unneeded semicolon KVM: PPC: Book3S HV: Use POWER9 SLBIA IH=6 variant to clear SLB KVM: PPC: Book3S HV: No need to clear radix host SLB before loading HPT guest KVM: PPC: Book3S HV: Fix radix guest SLB side channel KVM: PPC: Book3S HV: Remove support for running HPT guest on RPT host without mixed mode support KVM: PPC: Book3S HV: Introduce new capability for 2nd DAWR KVM: PPC: Book3S HV: Add infrastructure to support 2nd DAWR ...
