Huawei use the product code HUAWEI_PRODUCT_E353 (0x1506) for a
number of different devices, which each can appear with a number
of different descriptor sets. Different types of interfaces
can be identified by looking at the subclass and protocol fields
Subclass 1 protocol 8 is actually the data interface of a CDC
ECM set, with subclass 1 protocol 9 as the control interface.
Neither support serial data communcation, and cannot therefore
be supported by this driver.
At the same time, add a few other sets which appear if the
device is configured in "Windows mode" using this modeswitch

Commit 06222e491e663dac939f04b125c9dc52126a75c4 got the if wrong so that
it always evaluates as true. This is semantically harmless, but makes
SEEK_CUR and SEEK_SET needlessly query the server.
Rewrite the if to explicitly enumerate the cases we DO need a valid i_size
to make this code less fragile.

Found one system with UEFI/iBFT, kernel does not detect the iBFT during
iscsi_ibft module loading.
Root cause: on x86 (UEFI), we are calling of find_ibft_region() much earlier
- specifically in setup_arch() before ACPI is enabled.
Try to split acpi checking code out and call that later
At that time ACPI iBFT already get permanent mapped with ioremap.
So isa_virt_to_bus() will get wrong phys from right virt address.
We could just skip that phys address printing.
For legacy one, print the found address early.
-v2: update comments and description according to Konrad.
-v3: fix problem about module use case that is found by Konrad.
-v4: use acpi_get_table() instead of acpi_table_parse() to handle module use case that is found by Konrad again..

The test in fuse_file_llseek() "not SEEK_CUR or not SEEK_SET" always evaluates
to true.
This was introduced in 3.1 by commit 06222e49 (fs: handle SEEK_HOLE/SEEK_DATA
properly in all fs's that define their own llseek) and changed the behavior of
SEEK_CUR and SEEK_SET to always retrieve the file attributes. This is a
performance regression.

Fix two bugs in fuse_retrieve():
- retrieving more than one page would yield repeated instances of the
first page
- if more than FUSE_MAX_PAGES_PER_REQ pages were requested than the
request page array would overflow

beginning.

Exactly like roundup_pow_of_two(1), the rounddown version was buggy for
the case of a compile-time constant '1' argument. Probably because it
originated from the same code, sharing history with the roundup version
from before the bugfix (for that one, see commit 1a06a52ee1b0: "Fix
roundup_pow_of_two(1)").
However, unlike the roundup version, the fix for rounddown is to just
remove the broken special case entirely. It's simply not needed - the
generic code
1UL << ilog2(n)
does the right thing for the constant '1' argment too. The only reason
roundup needed that special case was because rounding up does so by
subtracting one from the argument (and then adding one to the result)
causing the obvious problems with "ilog2(0)".
But rounddown doesn't do any of that, since ilog2() naturally truncates
(ie "rounds down") to the right rounded down value. And without the
ilog2(0) case, there's no reason for the special case that had the wrong
value.
tl;dr: rounddown_pow_of_two(1) should be 1, not 0.

The old PowerMac swim3 driver has some "interesting" locking issues,
using a private lock and failing to lock the queue before completing
requests, which triggered WARN_ONs among others.
This rips out the private lock, makes everything operate under the
block queue lock, and generally makes things simpler.
We used to also share a queue between the two possible instances which
was problematic since we might pick the wrong controller in some cases,
so make the queue and the current request per-instance and use
queuedata to point to our private data which is a lot cleaner.
We still share the queue lock but then, it's nearly impossible to actually
use 2 swim3's simultaneously: one would need to have a Wallstreet
PowerBook, the only machine afaik with two of these on the motherboard,
and populate both hotswap bays with a floppy drive (the machine ships
only with one), so nobody cares...
While at it, add a little fix to clear up stale interrupts when loading
the driver or plugging a floppy drive in a bay.

the host is flagged as removable, mmc_suspend_host()

sync can get blocked trying to acquire host which is already

efi_call_phys_prelog() sets up a 1:1 mapping of the physical address
range in swapper_pg_dir. Instead of replacing then restoring entries
in swapper_pg_dir we should be using initial_page_table which already
contains the 1:1 mapping.
It's safe to blindly switch back to swapper_pg_dir in the epilog
because the physical EFI routines are only called before
efi_enter_virtual_mode(), e.g. before any user processes have been
forked. Therefore, we don't need to track which pgd was in %cr3 when
we entered the prelog.
The previous code actually contained a bug because it assumed that the
kernel was loaded at a physical address within the first 8MB of ram,
usually at 0x100000. However, this isn't the case with a
CONFIG_RELOCATABLE=y kernel which could have been loaded anywhere in
the physical address space.
Also delete the ancient (and bogus) comments about the page table
being restored after the lock is released. There is no locking.
