2021-03-12arm64: dts: qcom: sc7180: trogdor: Use ADC TM channel 0 instead of 1 for ↵Matthias Kaehlcke1-3/+3
charger temperature On trogdor the ADC thermal monitor is used for monitoring certain device temperatures. All trogdor boards have at least a thermistor for the charger temperature, optionally they may have others. Currently the ADC thermal monitor is configured to use channel 1 for the charger temperature. Given that all trogdor boards have the charger thermistor it makes more sense to use channel 0, and then let boards with other thermistors use channels 1, 2, 3, rather than 0, 2, 3.

2021-03-11x86/paravirt: Remove no longer needed 32-bit pvops cruftJuergen Gross5-123/+35
PVOP_VCALL4() is only used for Xen PV, while PVOP_CALL4() isn't used at all. Keep PVOP_CALL4() for 64 bits due to symmetry reasons. This allows to remove the 32-bit definitions of those macros leading to a substantial simplification of the paravirt macros, as those were the only ones needing non-empty "pre" and "post" parameters. PVOP_CALLEE2() and PVOP_VCALLEE2() are used nowhere, so remove them. Another no longer needed case is special handling of return types larger than unsigned long. Replace that with a BUILD_BUG_ON(). DISABLE_INTERRUPTS() is used in 32-bit code only, so it can just be replaced by cli. INTERRUPT_RETURN in 32-bit code can be replaced by iret. ENABLE_INTERRUPTS is used nowhere, so it can be removed.

2021-03-11powerpc/kexec_file: Restore FDT size estimation for kdump kernelThiago Jung Bauermann3-20/+10
kexec_fdt_totalsize_ppc64() includes the base FDT size in its size calculation, but commit 3c985d31ad66 ("powerpc: Use common of_kexec_alloc_and_setup_fdt()") changed the kexec code to use the generic function of_kexec_alloc_and_setup_fdt() which already includes the base FDT size. That change made the code overestimate the size a bit by counting twice the space required for the kernel command line and /chosen properties. Therefore change kexec_fdt_totalsize_ppc64() to calculate just the extra space needed by the kdump kernel, and change the function name so that it better reflects what the function is now doing.

2021-03-11x86/alternative: Support not-featureJuergen Gross2-5/+18
Add support for alternative patching for the case a feature is not present on the current CPU. For users of ALTERNATIVE() and friends, an inverted feature is specified by applying the ALT_NOT() macro to it, e.g.: ALTERNATIVE(old, new, ALT_NOT(feature)); Committer note: The decision to encode the NOT-bit in the feature bit itself is because a future change which would make objtool generate such alternative calls, would keep the code in objtool itself fairly simple. Also, this allows for the alternative macros to support the NOT feature without having to change them. Finally, the u16 cpuid member encoding the X86_FEATURE_ flags is not an ABI so if more bits are needed, cpuid itself can be enlarged or a flags field can be added to struct alt_instr after having considered the size growth in either cases.

2021-03-11arm64: mm: use a 48-bit ID map when possible on 52-bit VA buildsArd Biesheuvel3-6/+3
52-bit VA kernels can run on hardware that is only 48-bit capable, but configure the ID map as 52-bit by default. This was not a problem until recently, because the special T0SZ value for a 52-bit VA space was never programmed into the TCR register anwyay, and because a 52-bit ID map happens to use the same number of translation levels as a 48-bit one. This behavior was changed by commit 1401bef703a4 ("arm64: mm: Always update TCR_EL1 from __cpu_set_tcr_t0sz()"), which causes the unsupported T0SZ value for a 52-bit VA to be programmed into TCR_EL1. While some hardware simply ignores this, Mark reports that Amberwing systems choke on this, resulting in a broken boot. But even before that commit, the unsupported idmap_t0sz value was exposed to KVM and used to program TCR_EL2 incorrectly as well. Given that we already have to deal with address spaces being either 48-bit or 52-bit in size, the cleanest approach seems to be to simply default to a 48-bit VA ID map, and only switch to a 52-bit one if the placement of the kernel in DRAM requires it. This is guaranteed not to happen unless the system is actually 52-bit VA capable.

As Documentation/kbuild/llvm.rst notes, LLVM=1 switches the default of tools, but you can still override CC, LD, etc. individually. This LLVM=1 check is unneeded because each tool is already checked separately. "make CC=clang LD=ld.lld NM=llvm-nm AR=llvm-ar LLVM_IAS=1 menuconfig" should be able to enable Clang LTO.

2021-03-11Xen/gnttab: introduce common INVALID_GRANT_{HANDLE,REF}Jan Beulich2-3/+4
It's not helpful if every driver has to cook its own. Generalize xenbus'es INVALID_GRANT_HANDLE and pcifront's INVALID_GRANT_REF (which shouldn't have expanded to zero to begin with). Use the constants in p2m.c and gntdev.c right away, and update field types where necessary so they would match with the constants' types (albeit without touching struct ioctl_gntdev_grant_ref's ref field, as that's part of the public interface of the kernel and would require introducing a dependency on Xen's grant_table.h public header).

They're only used internally, and the layering violation they contain (x86) or imply (Arm) of calling HYPERVISOR_grant_table_op() strongly advise against any (uncontrolled) use from a module.

2021-03-10x86/perf: Use RET0 as default for guest_get_msrs to handle "no PMU" caseSean Christopherson2-10/+7
Initialize x86_pmu.guest_get_msrs to return 0/NULL to handle the "nop" case. Patching in perf_guest_get_msrs_nop() during setup does not work if there is no PMU, as setup bails before updating the static calls, leaving x86_pmu.guest_get_msrs NULL and thus a complete nop. Ultimately, this causes VMX abort on VM-Exit due to KVM putting random garbage from the stack into the MSR load list. Add a comment in KVM to note that nr_msrs is valid if and only if the return value is non-NULL.
