Analyze and fix the following issue in the Linux kernel code: efi/unaccepted: touch soft lockup during memory accept
Problem Details: Commit 50e782a86c98 ("efi/unaccepted: Fix soft lockups caused by parallel memory acceptance") has released the spinlock so other CPUs can do memory acceptance in parallel and not triggers softlockup on other CPUs. However the softlock up was intermittent shown up if the memory of the TD guest is large...

Analyze and fix the following issue in the Linux kernel code: drm/i915: Fix gt reset with GuC submission is disabled
Problem Details: Currently intel_gt_reset() kills the GuC and then resets requested engines. This is problematic because there is a dedicated CSB FIFO which only GuC can access and if that FIFO fills up, the hardware will block on the next context switch until there is space that means the system is effectively hung.

Analyze and fix the following issue in the Linux kernel code: regulator: change devm_regulator_get_enable_optional() stub to return Ok
Problem Details: The devm_regulator_get_enable_optional() should be a 'call and forget' API, meaning, when it is used to enable the regulators, the API does not provide a handle to do any further control of the regulators. It gives no real benefit to return an error from the stub if CONFIG_REGULATOR is not set. On the...
