HydrogenKernel Update

📦 *HydrogenKernel Update*

━━━━━━━━━━━━━━━━━━━━━━━━━━

📝 *Changelog*

• *Core & Upstream Updates:*

 - Upgraded kernel base to Linux 6.6.139.

 - Merged remote upstream branches (Linux stable and Android 15 LTS) for full GKI compliance.

 - Numerous bug fixes and stability improvements for Android GKI.

• *Root & Security:*

 - Integrated KernelSU-Next for seamless root management.

 - Improved get_dumpable() logic to enforce better user-space security.

 - Patched critical memory security bugs, including a Xen driver buffer overflow and a double-free crash exploit.

• *CPU & Thermal Management:*

 - Restored native thermal throttling and vendor power HAL limits to ensure predictable thermal behaviors, cool temperatures, and better battery backup.

 - Reverted problematic KVM, SCSI, netfilter, and thermal upstream updates that were causing active system bugs.

• *Performance & Memory Tweaks:*

 - fs/dcache: Decreased vfs_cache_pressure to 60 to retain directory/inode structures in cache longer, drastically reducing multi-tasking lag and micro-stutters.

 - Optimized touch sampling rates for significantly lower input lag.

 - Balanced governor tuning for peak CPU/GPU output under load.

• *Android & Hardware Fixes:*

 - Preserved kernel API (task_struct) for complete out-of-tree Android module compatibility.

 - Added critical structural exports for audio drivers (snd_soc) and memory allocators (dma_alloc/free_pages).

 - Fixed core hardware resource isolation issues on AMD Zen2 processors.

 - XFRM ESP: Prohibited in-place decryption on shared fragments to eliminate potential wireless packet data corruption.
