StormBreaker-v2 for Surya

▪️ Changelog:

• Fixed the issue where the phone would boot into fastboot after flashing kernel

• Made an attempt to reduce touch latency by 0.5-1ms by making it use block transfer mode for small transactions

• Disable Adreno driver logging

• ion: Improve performance

• iommu:msm: improve performance

• Disallow ashmem memory from being remapped

• Some upstreams and backports to mm

• Reduce M_MAX_READAHEAD to 128KB

• Add low_prio_worker thread to kgsl (Adds a new CFS thread for freeing GPU memory which increases performance when tearing down processes)

• msm:sde:rotator Async suspend/resume callbacks (improving suspend/resume latency.)

• Compiled with clang 12

• blkdev:switch to SSD mode, disable IO stats and entropy gathering (optimise for flash storage)

• ufs: Remove 10 ms CPU idle latency unvote timeout (saves power)

• pinctrl: Remove explicit barriers from mmio ops where unneeded (benefits things like i2c)

• Remove avb check from vendor

• Disable watchdog to reduce the amount of CPU work the system has to do

• Disable softlockup to reduce high latency spikes

• Disable all auditing messages for reduced overhead

• Enable noirqdebug to avoid the minor overhead added to every IRQ handled.

• Disable expedited RCU grace periods after boot for better energy efficiency in mobile devices and better real-time latency
