After revisiting the design, I believe `struct z_erofs_bvec` should
be page-based instead of folio-based due to the reasons below:
- The minimized memory mapping block is a page;
- Under the certain circumstances, only temporary pages needs to be
used instead of folios since refcount, mapcount for such pages are
unnecessary;
- Decompressors handle all types of pages including temporary pages,
not only folios.
When handling `struct z_erofs_bvec`, all folio-related information
is now accessed using the page_folio() helper.
The final goal of this round adaptation is to eliminate direct
accesses to `struct page` in the EROFS codebase, except for some
exceptions like `z_erofs_is_shortlived_page()` and
`z_erofs_page_is_invalidated()`, which require a new helper to
determine the memdesc type of an arbitrary page.
Actually large folios of compressed files seem to work now, yet I tend
to conduct more tests before officially enabling this for all scenarios.

Previously, a folio just contains one page. In order to enable large
folios, z_erofs_scan_folios() needs to handle multi-page folios.
First, this patch eliminates all gotos. Instead, the new loop deal
with multiple parts in each folio. It's simple to handle the parts
which belong to unmapped extents or fragment extents; but for encoded
extents, the page boundaries needs to be considered for `tight` and
`split` to keep inplace I/Os work correctly: when a part crosses the
page boundary, they needs to be reseted properly.
Besides, simplify `tight` derivation since Z_EROFS_PCLUSTER_HOOKED
has been removed for quite a while.

In the process of adding support for shared IRQ pins, a scenario
was accidentally created where adv7511_irq_process returned
prematurely causing the EDID to fail randomly.
Since the interrupt handler is broken up into two main helper functions,
update both of them to treat the helper functions as IRQ handlers. These
IRQ routines process their respective tasks as before, but if they
determine that actual work was done, mark the respective IRQ status
accordingly, and delay the check until everything has been processed.
This should guarantee the helper functions don't return prematurely
while still returning proper values of either IRQ_HANDLED or IRQ_NONE.

xfrm_policy_kill() is called at different places to delete xfrm
policy. It will call xfrm_pol_put(). But xfrm_dev_policy_delete() is
not called to free the policy offloaded to hardware.
The three commits cited here are to handle this issue by calling
xfrm_dev_policy_delete() outside xfrm_get_policy(). But they didn't
cover all the cases. An example, which is not handled for now, is
xfrm_policy_insert(). It is called when XFRM_MSG_UPDPOLICY request is
received. Old policy is replaced by new one, but the offloaded policy
is not deleted, so driver doesn't have the chance to release hardware
resources.
To resolve this issue for all cases, move xfrm_dev_policy_delete()
into xfrm_policy_kill(), so the offloaded policy can be deleted from
hardware when it is called, which avoids hardware resources leakage.

At this time, conntrack either returns NF_ACCEPT or NF_DROP.
To improve debuging it would be nice to be able to replace NF_DROP verdict
with NF_DROP_REASON() helper,
This helper releases the skb instantly (so drop_monitor can pinpoint
exact location) and returns NF_STOLEN.
Prepare call sites to deal with this before introducing such changes
in conntrack and nat core.

The only generic interface to execute asynchronously in the BH context is
tasklet; however, it's marked deprecated and has some design flaws. To
replace tasklets, BH workqueue support was recently added. A BH workqueue
behaves similarly to regular workqueues except that the queued work items
are executed in the BH context.
This patch converts drivers/mmc/* from tasklet to BH workqueue.

Some controllers may not be able to reach a bus clock as low as 400 KHz
due to a lack of sufficient divisors. In these cases, the SD card slot
becomes non-functional as Linux continuously attempts to set the bus
clock to 400 KHz. If the controller is incapable of getting that low,
set its minimum frequency instead. While this may eliminate some SD
cards, it allows those capable of operating at the controller's minimum
frequency to be used.

Commit c0e5f4e73a ("misc: rtsx: Add support for RTS5261") silently
removed RTSX_MS_CARD from its MFD cell, so rtsx_pci_ms isn't used
by any driver anymore.
Since there doesn't seem to any complaint, hence drop the driver.

When defined using bit-fields, the compiler takes care of packing the
bits in a memory-efficient way and frees us from defining
LANDLOCK_SHIFT_ACCESS_* by hand. The exact memory layout does not
matter in our use case.
The manual definition of LANDLOCK_SHIFT_ACCESS_* has resulted in bugs in
at least two recent patch sets [1] [2] where new kinds of handled access
rights were introduced.

As it turns out, clearing the BSS was not the right fix for the issue
that was ultimately fixed by commit decd347c2a ("x86/efistub:
Reinstate soft limit for initrd loading"), and given that the Windows
EFI loader becomes very unhappy when entered with garbage in BSS, this
is one thing that x86 PC EFI implementations can be expected to get
right.
So drop it from the pure PE entrypoint. The handover protocol entrypoint
still needs this - it is used by the flaky distro bootloaders that
barely implement PE/COFF at all.

The fail label is only used in a situation where the previous EFI API
call succeeded, and so status will be set to EFI_SUCCESS. Fix this, by
dropping the goto entirely, and call efi_exit() with the correct error
code.

0c18184de9 ("platform/x86: apple-gmux: support MMIO gmux on T2 Macs")
brought support for T2 Macs in apple-gmux. But in order to use dual GPU,
the integrated GPU has to be enabled. On such dual GPU EFI Macs, the EFI
stub needs to report that it is booting macOS in order to prevent the
firmware from disabling the iGPU.
This patch is also applicable for some non T2 Intel Macs.
