Implement support for a new note type NT_ARM64_ZT providing access to ZT0 when implemented. Since ZT0 is a register with constant size this is much simpler than for other SME state. As ZT0 is only accessible when PSTATE.ZA is set writes to ZT0 cause PSTATE.ZA to be set, the main alternative would be to return -EBUSY in this case but this seemed more constructive. Practical users are also going to be working with ZA anyway and have some understanding of the state. Signed-off-by:

Add a new signal context type for ZT which is present in the signal frame when ZA is enabled and ZT is supported by the system. In order to account for the possible addition of further ZT registers in the future we make the number of registers variable in the ABI, though currently the only possible number is 1. We could just use a bare list head for the context since the number of registers can be inferred from the size of the context but for usability and future extensibility we define a header with the number of registers and some reserved fields in it.

When the system supports SME2 the ZT0 register must be context switched as part of the floating point state. This register is stored immediately after ZA in memory and is only accessible when PSTATE.ZA is set so we handle it in the same functions we use to save and restore ZA. Signed-off-by:

When the system supports SME2 there is an additional register ZT0 which we must store when the task is using SME. Since ZT0 is accessible only when PSTATE.ZA is set just like ZA we allocate storage for it along with ZA, increasing the allocation size for the memory region where we store ZA and storing the data for ZT after that for ZA.

As well as a number of simple features which only add new instructions and require corresponding hwcaps SME2 introduces a new register ZT0 for which we must define ABI. Fortunately this is a fixed size 512 bits and therefore much more straightforward than the base SME state, the only wrinkle is that it is only accessible when ZA is accessible. While there is only a single register the architecture is written with a view to exensibility, including a number in the name, so follow this in the ABI. Signed-off-by:

In preparation for adding support for storage for ZT0 to the thread_struct rename za_state to sme_state. Since ZT0 is accessible when PSTATE.ZA is set just like ZA itself we will extend the allocation done for ZA to cover it, avoiding the need to further expand task_struct for non-SME tasks.

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.

After commit 5f217ccd ("fotg210-udc: Support optional external PHY"), the error code is re-assigned to 0 in fotg210_udc_probe(), if allocate or map memory fails after the assignment, it can't return an error code. Set the error code to -ENOMEM to fix this problem. Fixes: 5f217ccd ("fotg210-udc: Support optional external PHY") Signed-off-by:
