The SMM_CTL MSR not present feature was being open-coded for KVM. Add it to its newly added CPUID leaf 0x80000021 EAX proper.

The LFENCE always serializing feature bit was defined as scattered LFENCE_RDTSC and its native leaf bit position open-coded for KVM. Add it to its newly added CPUID leaf 0x80000021 EAX proper. With LFENCE_RDTSC in its proper place, the kernel's set_cpu_cap() will effectively synthesize the feature for KVM going forward. Also, DE_CFG[1] doesn't need to be set on such CPUs anymore.

Move code from __do_cpuid_func() to kvm_set_cpu_caps() in preparation for adding the features in their native leaf. Also drop the bit description comments as it will be more self-describing once the individual features are added. Whilst there, switch to using the more efficient cpu_feature_enabled() instead of static_cpu_has(). Note, LFENCE_RDTSC and "NULL selector clears base" are currently synthetic, Linux-defined feature flags as Linux tracking of the features predates AMD's definition. Keep the manual propagation of the flags from their synthetic counterparts until the kernel fully converts to AMD's definition, otherwise KVM would stop synthesizing the flags as intended.

Add support for CPUID leaf 80000021, EAX. The majority of the features will be used in the kernel and thus a separate leaf is appropriate.

Add the CPU feature bit for LKGS (Load "Kernel" GS). LKGS instruction is introduced with Intel FRED (flexible return and event delivery) specification. Search for the latest FRED spec in most search engines with this search pattern: site:intel.com FRED (flexible return and event delivery) specification LKGS behaves like the MOV to GS instruction except that it loads the base address into the IA32_KERNEL_GS_BASE MSR instead of the GS segment’s descriptor cache, which is exactly what Linux kernel does to load a user level GS base. Thus, with LKGS, there is no need to SWAPGS away from the kernel GS base. [ mingo: Minor tweaks to the description. ] Signed-off-by: H.

Currently, x86_spec_ctrl_base is read at boot time and speculative bits are set if Kconfig items are enabled. For example, IBRS is enabled if CONFIG_CPU_IBRS_ENTRY is configured, etc. These MSR bits are not cleared if the mitigations are disabled. This is a problem when kexec-ing a kernel that has the mitigation disabled from a kernel that has the mitigation enabled. In this case, the MSR bits are not cleared during the new kernel boot. As a result, this might have some performance degradation that is hard to pinpoint. This problem does not happen if the machine is (hard) rebooted because the bit will be cleared by default.

TPM 1 is sometimes broken across system suspends, due to races or locking issues or something else that haven't been diagnosed or fixed yet, most likely having to do with concurrent reads from the TPM's hardware random number generator driver. These issues prevent the system from actually suspending, with errors like: tpm tpm0: A TPM error (28) occurred continue selftest ... tpm tpm0: A TPM error (28) occurred attempting get random ... tpm tpm0: Error (28) sending savestate before suspend tpm_tis 00:08: PM: __pnp_bus_suspend(): tpm_pm_suspend+0x0/0x80 returns 28 tpm_tis 00:08: PM: dpm_run_callback(): pnp_bus_suspend+0x0/0x10 returns 28 tpm_tis 00:08: PM: failed to suspend: error 28 PM: Some devices failed to suspend, or early wake event detected This issue was partially fixed by 23393c64 ("char: tpm: Protect tpm_pm_suspend with locks"), in a last minute 6.1 commit that Linus took directly because the TPM maintainers weren't available. However, it seems like this just addresses the most common cases of the bug, rather than addressing it entirely. So there are more things to fix still, apparently. In lieu of actually fixing the underlying bug, just allow system suspend to continue, so that laptops still go to sleep fine. Later, this can be reverted when the real bug is fixed.

Commit 55d1cbbb ("hfs/hfsplus: use WARN_ON for sanity check") fixed a build warning by turning a comment into a WARN_ON(), but it turns out that syzbot then complains because it can trigger said warning with a corrupted hfs image. The warning actually does warn about a bad situation, but we are much better off just handling it as the error it is. So rather than warn about us doing bad things, stop doing the bad things and return -EIO. While at it, also fix a memory leak that was introduced by an earlier fix for a similar syzbot warning situation, and add a check for one case that historically wasn't handled at all (ie neither comment nor subsequent WARN_ON).

If we delay sending End Transfer for Setup TRB to be prepared, we need to check if the End Transfer was in preparation for a driver teardown/soft-disconnect. In those cases, just send the End Transfer command without delay. In the case of soft-disconnect, there's a very small chance the command may not go through immediately. But should it happen, the Setup TRB will be prepared during the polling of the controller halted state, allowing the command to go through then. In the case of disabling endpoint due to reconfiguration (e.g. set_interface(alt-setting) or usb reset), then it's driven by the host. Typically the host wouldn't immediately cancel the control request and send another control transfer to trigger the End Transfer command timeout.

When extending the last extent in the file within the last block, we wrongly computed the length of the last extent. This is mostly a cosmetical problem since the extent does not contain any data and the length will be fixed up by following operations but still.
