2020-02-12arm64: dts: fsl-imx8qm-apalis: spi: use pio modeMax Krummenacher
If using DMA mode the chip select gets deasserted and asserted again with each word in a transmission. PIO mode on the other hand asserts at the beginning of a transmission and de-asserts at the end which for most use-cases is prefered.

2020-01-09arm64: dts: meson: odroid-c2: Disable usb_otg bus to avoid power failed warningAnand Moon
[ Upstream commit 72c9b5f6f75fbc6c47e0a2d02bc3838a2a47c90a ] usb_otg bus needs to get initialize from the u-boot to be configured to used as power source to SBC or usb otg port will get configured as host device. Right now this support is missing in the u-boot and phy driver so to avoid power failed warning, we would disable this feature until proper fix is found.

2020-01-09arm64: Revert support for execute-only user mappingsCatalin Marinas
commit 24cecc37746393432d994c0dbc251fb9ac7c5d72 upstream. The ARMv8 64-bit architecture supports execute-only user permissions by clearing the PTE_USER and PTE_UXN bits, practically making it a mostly privileged mapping but from which user running at EL0 can still execute. The downside, however, is that the kernel at EL1 inadvertently reading such mapping would not trip over the PAN (privileged access never) protection. Revert the relevant bits from commit cab15ce604e5 ("arm64: Introduce execute-only page access permissions") so that PROT_EXEC implies PROT_READ (and therefore PTE_USER) until the architecture gains proper support for execute-only user mappings.

2019-12-31KVM: arm64: Ensure 'params' is initialised when looking up sys registerWill Deacon
commit 1ce74e96c2407df2b5867e5d45a70aacb8923c14 upstream. Commit 4b927b94d5df ("KVM: arm/arm64: vgic: Introduce find_reg_by_id()") introduced 'find_reg_by_id()', which looks up a system register only if the 'id' index parameter identifies a valid system register. As part of the patch, existing callers of 'find_reg()' were ported over to the new interface, but this breaks 'index_to_sys_reg_desc()' in the case that the initial lookup in the vCPU target table fails because we will then call into 'find_reg()' for the system register table with an uninitialised 'param' as the key to the lookup. GCC 10 is bright enough to spot this (amongst a tonne of false positives, but hey!): | arch/arm64/kvm/sys_regs.c: In function ‘index_to_sys_reg_desc.part.0.isra’: | arch/arm64/kvm/sys_regs.c:983:33: warning: ‘params.Op2’ may be used uninitialized in this function [-Wmaybe-uninitialized] | 983 | (u32)(x)->CRn, (u32)(x)->CRm, (u32)(x)->Op2); | [...] Revert the hunk of 4b927b94d5df which breaks 'index_to_sys_reg_desc()' so that the old behaviour of checking the index upfront is restored.

2019-12-31arm64: psci: Reduce the waiting time for cpu_psci_cpu_kill()Yunfeng Ye
[ Upstream commit bfcef4ab1d7ee8921bc322109b1692036cc6cbe0 ] In cases like suspend-to-disk and suspend-to-ram, a large number of CPU cores need to be shut down. At present, the CPU hotplug operation is serialised, and the CPU cores can only be shut down one by one. In this process, if PSCI affinity_info() does not return LEVEL_OFF quickly, cpu_psci_cpu_kill() needs to wait for 10ms. If hundreds of CPU cores need to be shut down, it will take a long time. Normally, there is no need to wait 10ms in cpu_psci_cpu_kill(). So change the wait interval from 10 ms to max 1 ms and use usleep_range() instead of msleep() for more accurate timer. In addition, reducing the time interval will increase the messages output, so remove the "Retry ..." message, instead, track time and output to the the sucessful message.

commit 1e5e929c009559bd7e898ac8e17a5d01037cb057 upstream. Commit 34993594181d ("arm64: tegra: Enable HDMI on Jetson TX1") added a regulator for HDMI on the Jetson TX1 platform. This regulator has an active high enable, but the GPIO specifier for enabling the regulator incorrectly defines it as active-low. This causes the following warning to occur on boot ... WARNING KERN regulator@10 GPIO handle specifies active low - ignored The fixed-regulator binding does not use the active-low flag from the gpio specifier and purely relies of the presence of the 'enable-active-high' property to determine if it is active high or low (if this property is omitted). Fix this warning by setting the GPIO to active-high in the GPIO specifier which aligns with the presense of the 'enable-active-high' property.

[ Upstream commit a96a33b1ca57dbea4285893dedf290aeb8eb090b ] For cases where there is a mismatch in ARMv8.2-LVA support between CPUs we have to be careful in allowing secondary CPUs to boot if 52-bit virtual addresses have already been enabled on the boot CPU. This patch adds code to the secondary startup path. If the boot CPU has enabled 52-bit VAs then ID_AA64MMFR2_EL1 is checked to see if the secondary can also enable 52-bit support. If not, the secondary is prevented from booting and an error message is displayed indicating why. Technically this patch could be implemented using the cpufeature code when considering 52-bit userspace support. However, we employ low level checks here as the cpufeature code won't be able to run if we have mismatched 52-bit kernel va support.

commit e4ba15debcfd27f60d43da940a58108783bff2a6 upstream. The bad_mode() handler is called if we encounter an uunknown exception, with the expectation that the subsequent call to panic() will halt the system. Unfortunately, if the exception calling bad_mode() is taken from EL0, then the call to die() can end up killing the current user task and calling schedule() instead of falling through to panic(). Remove the die() call altogether, since we really want to bring down the machine in this "impossible" case.

This issue came up with SystemTap when it tries to build variety of .i files for its own generated kernel modules trying to figure given kernel features/capabilities. The issue is that prepare0 is defined in top level Makefile only if KBUILD_EXTMOD is not defined. .i file rule depends on prepare and in case KBUILD_EXTMOD defined top level Makefile contains empty rule for prepare. But after mentioned commit arch/arm64/Makefile would introduce dependency on prepare0 through its own prepare target.
