[PATCH] x86/cpu/intel: Detect TME keyid bits before setting MTRR mask registers

by Paolo Bonzini

MKTME repurposes the high bit of physical address to key id for encryption key and, even though MAXPHYADDR in CPUID[0x80000008] remains the same, the valid bits in the MTRR mask register are based on the reduced number of physical address bits. detect_tme() in arch/x86/kernel/cpu/intel.c detects TME and subtracts it from the total usable physical bits, but it is called too late. Move the call to early_init_intel() so that it is called in setup_arch(), before MTRRs are setup. This fixes boot on some TDX-enabled systems which until now only worked with "disable_mtrr_cleanup". Without the patch, the values written to the MTRRs mask registers were 52-bit wide (e.g. 0x000fffff_80000800) and the writes failed; with the patch, the values are 46-bit wide, which matches the reduced MAXPHYADDR that is shown in /proc/cpuinfo.

[PATCH v2 0/3] HID: bpf: couple of upstream fixes

by Benjamin Tissoires

Hi, This is the v2 of this series of HID-BPF fixes. I have forgotten to include a Fixes tag in the first patch and got a review from Andrii on patch 2. And this first patch made me realize that something was fishy in the refcount of the hid devices. I was not crashing the system even if I accessed the struct hid_device after hid_destroy_device() was called, which was suspicious to say the least. So after some debugging I found the culprit and realized that I had a pretty nice memleak as soon as one HID-BPF program was attached to a HID device. The good thing though is that this ref count prevents a crash in case a HID-BPF program attempts to access a removed HID device when hid_bpf_allocate_context() has been called but not yet released. Anyway, for reference, the cover letter of v1: --- Hi, these are a couple of fixes for hid-bpf. The first one should probably go in ASAP, after the reviews, and the second one is nice to have and doesn't hurt much.

[PATCH] irqchip/gic-v3-its: Restore quirk probing for ACPI-based systems

by Marc Zyngier

While refactoring the way the ITSs are probed, the handling of quirks applicable to ACPI-based platforms was lost. As a result, systems such as HIP07 lose their GICv4 functionnality, and some other may even fail to boot, unless they are configured to boot with DT. Move the enabling of quirks into its_probe_one(), making it common to all firmware implementations.

Because such machines use tlb-based per-cpu base address rather than dmw-based per-cpu base address, resulting per-cpu variables can only be accessed after tlb_init(). But rcutree_report_cpu_starting() is now called before tlb_init() and accesses per-cpu variables indeed. Since the original patch want to avoid the lockdep warning caused by page allocation in tlb_init(), we can move rcutree_report_cpu_starting() to tlb_init() where after tlb exception configuration but before page allocation.
