f949dd5c90 kernel: Set CONFIG_FRAME_WARN depending on target
This set the CONFIG_FRAME_WARN option depending on some target settings.
It will use the default from the upstream kernel and not the hard coded
value of 1024 now.

94884f3904 mediatek: sync MT7988 USXGMII with SDK driver
The USXGMII driver in SDK was heavily refactored, some bugs have been
fixed and it has switched to use phylink_pcs. Follow up with changes
in SDK driver and sync our on-top-of-mainline driver with the SDK
driver.

f7d0a4797f generic: mt7530: backport support for the MT7988 built-in switch
Backport commits adding support for the MT7988 built-in switch to the
mt7530 driver.

This change results in the Kconfig symbol NET_DSA_MT7530 to be extended
by NET_DSA_MT7530_MDIO (everything formally covered by NET_DSA_MT7530)
and NET_DSA_MT7530_MMIO (a new driver for the MMIO-connected built-in
switch of the MT7988 SoC).

Select NET_DSA_MT7530_MDIO for all targets previously selecting
NET_DSA_MT7530, with the exception of mediatek/filogic which also
selects NET_DSA_MT7530_MMIO.

5df84814bb kernel: enable (ARM|ARM64)_MODULE_PLTS in generic config
This allows loading modules with large memory requirements, recently needed
while testing on armvirt/32. Past forum discussions [1] and bug reports [2]
also raised this and the ipq806x target already set it in response [3].
Given this increases kernel image size by only ~1KB, is generally useful on
multi-platform kernels, and enabled by default on upstream arm32 Linux, add
it to the generic config.

The setting has similar utility on arm64, is a requirement for KASLR, and
already enabled on most OpenWrt aarch64 targets, so pull this into the
top-level generic config.

3980dfcd05 kernel: fix handling of CONFIG_DYNAMIC_DEBUG
Since CONFIG_DYNAMIC_DEBUG is already managed via the KERNEL_DYNAMIC_DEBUG
setting in Config-kernel.in (default N), remove or disable it in target
configs which unconditionally enable it, along with the related setting
CONFIG_DYNAMIC_DEBUG_CORE. This saves several KB in the kernels for
ipq40xx, ipq806x, filogic, mt7622, qoriq, and sunxi.

kernel: Activate CONFIG_SLAB_FREELIST_RANDOM
This activates CONFIG_SLAB_FREELIST_RANDOM.
This option make the free list less predictable. This makes it harder to
exploit heap based security vulnerabilities.

This adds a little bit more code to the kernel and a small additional
compute overhead.

This option is activated in Debian by default.

Early versions (?) of the RTL8221B PHY cannot be identified in a regular

Implement custom identify function using the PKGID instead of iterating
over the implemented MMDs to work-around this problem.

Several factors contributed to this issue:

 1. The mtk_bmt driver recursively calls its scan_bmt() helper function
    during device initialization, while looking for a valid block
    mapping table (BMT).

 2. Commit fa4dc86e98 ("kernel: backport MEMREAD ioctl"):

      - increased the size of some stack-allocated structures (like
	struct mtd_oob_ops, used in bbt_nand_read(), which is indirectly
	called from scan_bmt()),

      - increased the stack size for some functions (for example,
	spinand_mtd_read(), which is indirectly called from scan_bmt(),
	now uses an extra stack-allocated struct mtd_ecc_stats).

 3. OpenWrt currently compiles the kernel with the
    -fno-optimize-sibling-calls flag, which prevents tail-call
    optimization.

Collectively, all of these factors caused stack usage in the mtk_bmt
driver to grow excessively large, triggering stack overflows.

Recursion is not really necessary in scan_bmt() as it simply iterates
over flash memory blocks in reverse order, looking for a valid BMT.
Refactor the logic contained in the scan_bmt() and read_bmt() functions
in target/linux/generic/files/drivers/mtd/nand/mtk_bmt_v2.c so that deep
recursion is prevented (and therefore also any potential stack overflows
it may cause).

2bab7d273e kernel: Initialize RNG using CPU RNG and bootloader
This activates the following kernel options by default:
* CONFIG_RANDOM_TRUST_CPU
* CONFIG_RANDOM_TRUST_BOOTLOADER

With these option Linux will also use data from the CPU RNG e.g. RDRAND
and the bootloader to initialize the Linux RNG if such sources are
available.
These random bits are used in addition to the other sources, no other
sources are getting deactivated. I read that the Chacha mixer isn't
vulnerable to injected entropy, so this should not be a problem even if
these sources might inject bad random data.

The Linux kernel suggests to activate both options, Debian also
activates them. This does not increase kernel code size.

de0ed4ffbf generic: Convert incorrect generic/5.15 patches again
OpenWrt's developer guide prefers having actual patches so they an be
sent upstream more easily.

However, in the case of hack-5.15 patches which are not meant for
upstream, adding proper fields allows for `git am` to properly function.

This commit tries to rectify that, by digging in the history to find
where and how it was first added.

The previous attempt to replace an open coded paged read in the RealTek
Ethernet PHY driver was too naive and resulted in breaking the r8169
PCIe Ethernet driver which also makes use of the RealTek Ethernet PHY
driver.
Fix this by instead of using the (not yet populated) paged operations
rather use rtl821x_write_page and protect the whole paged read operation
using the MDIO bus mutex.
