After it is not zero, the preceding member of the next node will no longer belong to the valid area of the previous alloc node.
Due to the existence of precedence, the memory block size of the node can only be aligned with sizeof(mmsize_t).
This configuration will be applied in the following scenarios when set 8:
ARM64 MTE hardware tag KASan, which requires the tag's memory address to be 16-byte aligned and the memory size must also be 16-byte aligned

If the NET_TCPBACKLOG configuration is not enabled, no I/O event will be
triggered for the socket file descriptor in poll/epoll. As a result, the
connection will not be accepted, leading to a failure in the TCP handshake.
The problem is that users may not have noticed this configuration,
no event will be received when polling the socket fd.

1. When the Clang compiler turns on "-fsanitize=kernel-address", inlining, global variables, and stack detection are enabled by default and must be turned off manually.
2. -mllvm is the parameter passing method of Clang, and --param is the parameter passing method of GCC
After the modification, KASan compilation and operation will be supported for Clang 18 and above

error: unpredictable STXR instruction, status is also a source
99 | "stxr %w0, %1, [%2] \n"
| ^
<inline asm>:5:10: note: instantiated into assembly here
5 | stxr w10, x10, [x9]
Using w0 to pass the result can cause the "status register is also a source" problem, resulting in unpredictable behavior.

The ARM64 instruction ADD has a 12-bit limit (0 - 4095) for immediate values, but here we try to use a symbolic address (.Linitparms) as an immediate value, which does not comply with the ARM64 instruction set rules.

Since the spinlock_type.h is designed to avoid including atomic.h in
the userspace, we should remove `atomic.h` inclusion in spinlock_type.h.

Adds a defconfig for SDMMC over SPI to the following boards:
esp32-devkitc, esp32s2-saola-1 and esp32s3-devkit.
Renames the defconfig name for:
esp32-lyrat and esp32-wrover-kit.
