2017-02-10mtd: spi-nor: add dt support for Everspin MRAMsUwe Kleine-König1-0/+2
The MR25 family doesn't support JEDEC, so they need explicit mentioning in the list of supported spi IDs. This makes it possible to add these using for example: compatible = "everspin,mr25h40"; There was already an entry for mr25h256. Move that one out of the "keep for compatibility" section and put in a new group for Everspin MRAMs. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Acked-by: Rob Herring <robh@kernel.org> Signed-off-by: Cyrille Pitchen <cyrille.pitchen@atmel.com>

2017-02-10arm64: Work around Falkor erratum 1003Christopher Covington1-0/+1
The Qualcomm Datacenter Technologies Falkor v1 CPU may allocate TLB entries using an incorrect ASID when TTBRx_EL1 is being updated. When the erratum is triggered, page table entries using the new translation table base address (BADDR) will be allocated into the TLB using the old ASID. All circumstances leading to the incorrect ASID being cached in the TLB arise when software writes TTBRx_EL1[ASID] and TTBRx_EL1[BADDR], a memory operation is in the process of performing a translation using the specific TTBRx_EL1 being written, and the memory operation uses a translation table descriptor designated as non-global. EL2 and EL3 code changing the EL1&0 ASID is not subject to this erratum because hardware is prohibited from performing translations from an out-of-context translation regime. Consider the following pseudo code. write new BADDR and ASID values to TTBRx_EL1 Replacing the above sequence with the one below will ensure that no TLB entries with an incorrect ASID are used by software. write reserved value to TTBRx_EL1[ASID] ISB write new value to TTBRx_EL1[BADDR] ISB write new value to TTBRx_EL1[ASID] ISB When the above sequence is used, page table entries using the new BADDR value may still be incorrectly allocated into the TLB using the reserved ASID. Yet this will not reduce functionality, since TLB entries incorrectly tagged with the reserved ASID will never be hit by a later instruction.

From PCIe base spec rev 3.0, chapter "6.6.1. Conventional Reset": To allow components to perform internal initialization, system software must wait a specified minimum period following the end of a Conventional Reset of one or more devices before it is permitted to issue Configuration Requests to those devices. With a Downstream Port that does not support Link speeds greater than 5.0 GT/s, software must wait a minimum of 100 ms before sending a Configuration Request to the device immediately below that Port.

KVM: MIPS: GVA/GPA page tables, dirty logging, SYNC_MMU etc Numerous MIPS KVM fixes, improvements, and features for 4.11, many of which continue to pave the way for VZ support, the most interesting of which are: - Add GVA->HPA page tables for T&E, to cache GVA mappings. - Generate fast-path TLB refill exception handler which loads host TLB entries from GVA page table, avoiding repeated guest memory translation and guest TLB lookups. - Use uaccess macros when T&E needs to access guest memory, which with GVA page tables and the Linux TLB refill handler improves robustness against TLB faults and fixes EVA hosts. - Use BadInstr/BadInstrP registers when available to obtain instruction encodings after a synchronous trap. - Add GPA->HPA page tables to replace the inflexible linear array, allowing for multiple sparsely arranged memory regions. - Properly implement dirty page logging. - Add KVM_CAP_SYNC_MMU support so that changes in GPA mappings become effective in guests even if they are already running, allowing for copy-on-write, KSM, idle page tracking, swapping, and guest memory ballooning. - Add KVM_CAP_READONLY_MEM support, so writes to specified memory regions are treated as MMIO. - Implement proper CP0_EBase support in T&E. - Expose a few more missing CP0 registers to userland. - Add KVM_CAP_NR_VCPUS and KVM_CAP_MAX_VCPUS support, and allow up to 8 VCPUs to be created in a VM. - Various cleanups and dropping of dead and duplicated code.
2017-02-07Merge branch 'kvm-ppc-next' of git://git.kernel.org/pub/scm/linux/kernel/git/paulus/powerpc into HEADPaolo Bonzini1-7/+187
The big feature this time is support for POWER9 using the radix-tree MMU for host and guest. This required some changes to arch/powerpc code, so I talked with Michael Ellerman and he created a topic branch with this patchset, which I merged into kvm-ppc-next and which Michael will pull into his tree. Michael also put in some patches from Nick Piggin which fix bugs in the interrupt vector code in relocatable kernels when coming from a KVM guest. Other notable changes include: * Add the ability to change the size of the hashed page table, from David Gibson. * XICS (interrupt controller) emulation fixes and improvements, from Li Zhong. * Bug fixes from myself and Thomas Huth. These patches define some new KVM capabilities and ioctls, but there should be no conflicts with anything else currently upstream, as far as I am aware.
