2021-02-10KVM: PPC: Book3S HV: Allow nested guest creation when L0 hv_guest_state > L1Ravi Bangoria2-12/+60
On powerpc, L1 hypervisor takes help of L0 using H_ENTER_NESTED hcall to load L2 guest state in cpu. L1 hypervisor prepares the L2 state in struct hv_guest_state and passes a pointer to it via hcall. Using that pointer, L0 reads/writes that state directly from/to L1 memory. Thus L0 must be aware of hv_guest_state layout of L1. Currently it uses version field to achieve this. i.e. If L0 hv_guest_state.version != L1 hv_guest_state.version, L0 won't allow nested kvm guest. This restriction can be loosened up a bit. L0 can be taught to understand older layout of hv_guest_state, if we restrict the new members to be added only at the end, i.e. we can allow nested guest even when L0 hv_guest_state.version > L1 hv_guest_state.version. Though, the other way around is not possible.

Actions Semi ARM DT changes for v5.12: Updates to the existing S500 ARM SoC. Support has been added for CMU (Clock Management Unit), Reset controller, DMA, Pinctrl/GPIO, MMC, I2C and SIRQ (interrupt controller). Since the CMU support is added, the dummy fixed clock used for the UART controller has been removed for all S500 based boards and proper UART clock from CMU is used. Added uSD support and I2C pinctrl configuration for Roseapplepi board based on S500 SoC. This will make the board boot mainline with a distro from uSD card. The I2C pinctrl config is added specifically for the PMIC which is currently under review. * tag 'actions-arm-dt-for-v5.12' of git://git.kernel.org/pub/scm/linux/kernel/git/mani/linux-actions: arm: dts: owl-s500-roseapplepi: Add I2C pinctrl configuration arm: dts: owl-s500-roseapplepi: Add uSD support arm: dts: owl-s500: Add SIRQ controller arm: dts: owl-s500: Add I2C support arm: dts: owl-s500: Add MMC support arm: dts: owl-s500: Add pinctrl & GPIO support arm: dts: owl-s500: Add DMA controller arm: dts: owl-s500: Add Reset controller arm: dts: owl-s500: Set CMU clocks for UARTs arm: dts: owl-s500: Add Clock Management Unit Link: https://lore.kernel.org/r/20210205050346.GA7619@thinkpad Signed-off-by: Arnd Bergmann <arnd@arndb.de>

2021-02-09s390/vtime: use cpu alternative for stck/stckfHeiko Carstens1-11/+8
Use a cpu alternative to switch between stck and stckf instead of making it compile time dependent. This will also make kernels compiled for old machines, but running on newer machines, use stckf. Signed-off-by: Heiko Carstens <hca@linux.ibm.com> Signed-off-by: Vasily Gorbik <gor@linux.ibm.com>

2021-02-09s390/vtime: fix inline assembly clobber listHeiko Carstens1-1/+2
The stck/stckf instruction used within the inline assembly within do_account_vtime() changes the condition code. This is not reflected with the clobber list, and therefore might result in incorrect code generation. It seems unlikely that the compiler could generate incorrect code considering the surrounding C code, but it must still be fixed.

Use the passed in vdso_data pointer instead of calculating it again. This is also required as a prerequisite for vdso time namespaces: if a process is part of a time namespace __arch_get_vdso_data() will return a pointer to the time namespace data page instead of the vdso data page, which is not what __arch_get_hw_counter() expects.

2021-02-09s390/pci: refactor zpci_create_device()Niklas Schnelle4-57/+48
Currently zpci_create_device() is only called in clp_add_pci_device() which allocates the memory for the struct zpci_dev being created. There is little separation of concerns as only both functions together can create a zpci_dev and the only CLP specific code in clp_add_pci_device() is a call to clp_query_pci_fn(). Improve this by removing clp_add_pci_device() and refactor zpci_create_device() such that it alone creates and initializes the zpci_dev given the FID and Function Handle. For this we need to make clp_query_pci_fn() non-static. While at it remove the function handle parameter since we can just take that from the zpci_dev. Also move adding to the zpci_list to after the zdev has been fully created which eliminates a window where a partially initialized zdev can be found by get_zdev_by_fid().
