[Deepin-Kernel-SIG] [linux 6.6-y] [Upstream] Update kernel base to 6.6.100

[opsiff]

Update kernel base to 6.6.100.

Summary by Sourcery

Update kernel base to 6.6.100, merging the upstream stable 6.6.100 release which includes numerous driver fixes, subsystem improvements, and architecture support enhancements.

Bug Fixes:

• Fix L2CAP MTU negotiation per Bluetooth 6.1 spec for ERTM channels
• Resolve USB hub resume path to allow SS link training before runtime suspend
• Correct SPI validation to support octal mode in both TX and RX
• Address various resource handling and reference bugs in RXRPC, SMB oplock breaks, and wangxun Ethernet driver

Enhancements:

• Add ARM64 SME CPU feature detection and matching in arm64 ELF HWCAP
• Enhance Bluetooth btusb firmware loader to extract board IDs and unify NVM naming
• Automate VLAN ID 0 hardware filter addition/removal on device up/down
• Improve PWM regulator boot-on initialization to maintain output stability
• Support mux-state selection and deselection in OMAP I²C driver
• Validate Comedi insnlist lengths and pad minimal sample counts
• Strengthen nf_conntrack hash insertion by ordering confirmed‐bit sets after RCU insertion
• Refine io_uring connect logic to handle in-progress errors and retrieve socket error codes

Build:

• Bump kernel version macros to SUBLEVEL 100

Reviewer's Guide

This PR updates the kernel base to 6.6.100 by bumping the version in Makefile and merging a large set of upstream commits. The changes include driver fixes and feature enhancements across Bluetooth (QCA firmware naming), USB (Tegra XUSB, core hub resume), networking (VLAN zero filtering, QFQ scheduler, netfilter), various platform drivers (PWM regulator, I²C mux, Comedi), arch support (ARM64 SME), BPF JIT and selftests, plus numerous cleanups and small fixes.

Hey @opsiff - I've reviewed your changes - here's some feedback:

• This patchset spans numerous subsystems and drivers; please consider splitting it into smaller, subsystem-focused commits or series to make review and backporting more manageable.
• Several new error paths (e.g., after dma_map or kcalloc) allocate resources before failing—ensure every failure branch properly cleans up allocated buffers, mappings, and registrations to prevent leaks.
• For all newly added delayed_work or workqueue items (e.g., hub_post_resume_work), verify that they’re always initialized, flushed, and canceled in corresponding removal or teardown paths to avoid use-after-free or stray work execution.
