2018-10-08mmc: uniphier-sd: add UniPhier SD/eMMC controller driverMasahiro Yamada1-0/+1
Here is another TMIO MMC variant found in Socionext UniPhier SoCs. As commit b6147490e6aa ("mmc: tmio: split core functionality, DMA and MFD glue") said, these MMC controllers use the IP from Panasonic. However, the MMC controller in the TMIO (Toshiba Mobile IO) MFD chip was the first upstreamed user of this IP. The common driver code for this IP is now called 'tmio-mmc-core' in Linux although it is a historical misnomer. Anyway, this driver select's MMC_TMIO_CORE to borrow the common code from tmio-mmc-core.c Older UniPhier SoCs (LD4, Pro4, sLD8) support the external DMA engine like renesas_sdhi_sys_dmac.c. The difference is UniPhier SoCs use a single DMA channel whereas Renesas chips request separate channels for RX and TX. Newer UniPhier SoCs (Pro5 and later) support the internal DMA engine like renesas_sdhi_internal_dmac.c The register map is almost the same, so I guess Renesas and Socionext use the same internal DMA hardware. The main difference is, the register offsets are doubled for Renesas. Renesas Socionext SDHI UniPhier DM_CM_DTRAN_MODE 0x820 0x410 DM_CM_DTRAN_CTRL 0x828 0x414 DM_CM_RST 0x830 0x418 DM_CM_INFO1 0x840 0x420 DM_CM_INFO1_MASK 0x848 0x424 DM_CM_INFO2 0x850 0x428 DM_CM_INFO2_MASK 0x858 0x42c DM_DTRAN_ADDR 0x880 0x440 DM_DTRAN_ADDREX --- 0x444 This comes from the difference of host->bus_shift; 2 for Renesas SoCs, and 1 for UniPhier SoCs. Also, the datasheet for UniPhier SoCs defines DM_DTRAN_ADDR and DM_DTRAN_ADDREX as two separate registers. It could be possible to factor out the DMA common code by introducing some hooks to cope with platform quirks, but this patch does not touch that for now.

2018-09-26s390: vfio-ap: base implementation of VFIO AP device driverTony Krowiak1-0/+10
Introduces a new AP device driver. This device driver is built on the VFIO mediated device framework. The framework provides sysfs interfaces that facilitate passthrough access by guests to devices installed on the linux host. The VFIO AP device driver will serve two purposes: 1. Provide the interfaces to reserve AP devices for exclusive use by KVM guests. This is accomplished by unbinding the devices to be reserved for guest usage from the zcrypt device driver and binding them to the VFIO AP device driver. 2. Implements the functions, callbacks and sysfs attribute interfaces required to create one or more VFIO mediated devices each of which will be used to configure the AP matrix for a guest and serve as a file descriptor for facilitating communication between QEMU and the VFIO AP device driver. When the VFIO AP device driver is initialized: * It registers with the AP bus for control of type 10 (CEX4 and newer) AP queue devices. This limitation was imposed due to: 1. A desire to keep the code as simple as possible; 2. Some older models are no longer supported by the kernel and others are getting close to end of service. 3. A lack of older systems on which to test older devices. The probe and remove callbacks will be provided to support the binding/unbinding of AP queue devices to/from the VFIO AP device driver. * Creates a matrix device, /sys/devices/vfio_ap/matrix, to serve as the parent of the mediated devices created, one for each guest, and to hold the APQNs of the AP devices bound to the VFIO AP device driver.

Thomas writes: "A set of fixes for x86: - Resolve the kvmclock regression on AMD systems with memory encryption enabled. The rework of the kvmclock memory allocation during early boot results in encrypted storage, which is not shareable with the hypervisor. Create a new section for this data which is mapped unencrypted and take care that the later allocations for shared kvmclock memory is unencrypted as well. - Fix the build regression in the paravirt code introduced by the recent spectre v2 updates. - Ensure that the initial static page tables cover the fixmap space correctly so early console always works. This worked so far by chance, but recent modifications to the fixmap layout can - depending on kernel configuration - move the relevant entries to a different place which is not covered by the initial static page tables. - Address the regressions and issues which got introduced with the recent extensions to the Intel Recource Director Technology code. - Update maintainer entries to document reality" * 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/mm: Expand static page table for fixmap space MAINTAINERS: Add X86 MM entry x86/intel_rdt: Add Reinette as co-maintainer for RDT MAINTAINERS: Add Borislav to the x86 maintainers x86/paravirt: Fix some warning messages x86/intel_rdt: Fix incorrect loop end condition x86/intel_rdt: Fix exclusive mode handling of MBA resource x86/intel_rdt: Fix incorrect loop end condition x86/intel_rdt: Do not allow pseudo-locking of MBA resource x86/intel_rdt: Fix unchecked MSR access x86/intel_rdt: Fix invalid mode warning when multiple resources are managed x86/intel_rdt: Global closid helper to support future fixes x86/intel_rdt: Fix size reporting of MBA resource x86/intel_rdt: Fix data type in parsing callbacks x86/kvm: Use __bss_decrypted attribute in shared variables x86/mm: Add .bss..decrypted section to hold shared variables

Commit 92f9ccca4c08 ("PCI: mobiveil: Add Mobiveil PCIe Host Bridge IP driver DT bindings") managed to add a MAINTAINERS entry where it does not really belong (ie in the middle of a totally unrelated series of entries and in the wrong alphabetical order).

Two relatively high LOCs are about the (rather simple) conversion of uapi integer types in topology API, and a regression fix about HDMI hotplug notification on AMD HD-audio.
