The irq handling is currently split between the irq handler
and the threaded irq handler. Some of the handling (such as
dma related stuffs) done within the irq handler might sleep or
take some time leading to issues if the kernel is built with
realtime constraints. In order to fix that, perform an overall
rework to perform most of the job within the threaded handler
and only keep fifo access in the non threaded handler.

On the Dell XPS 15 7590/0VYV0G, BIOS 1.24.0 09/11/2023, Linux prints the
warning below.
i801_smbus 0000:00:1f.4: Accelerometer lis3lv02d is present on SMBus but its address is unknown, skipping registration
Following the same suggestions by Wolfram Sang as for the Dell Precision

address 0x29.

Now that the driver core can properly handle constant struct bus_type,
move the i2c_bus_type variable to be a constant structure as well, placing
it into read-only memory which can not be modified at runtime.
Note, the sound/soc/rockchip/rk3399_gru_sound.c also needed tweaking as
it decided to save off a pointer to a bus type for internal stuff, and
it was using the i2c_bus_type as well.

I originally restricted i2c_register_spd() to only support systems
with up to 4 memory slots, so that we can experiment with it on
a limited numbers of systems. It's been more than 3 years and it
seems to work just fine, so the time has come to lift this arbitrary
limitation.
The maximum number of memory slots which can be connected to a single
I2C segment is 8, so support that many SPD EEPROMs. Any system with
more than 8 memory slots would have either multiple SMBus channels
or SMBus multiplexing, so it would need dedicated care. We'll get to
that later as needed.

To properly handle ACK on the bus when transferring more than one
message in polling mode, move the polling handling loop from
s3c24xx_i2c_message_start() to s3c24xx_i2c_doxfer(). This way
i2c_s3c_irq_nextbyte() is always executed till the end, properly
acknowledging the IRQ bits and no recursive calls to
i2c_s3c_irq_nextbyte() are made.
While touching this, also fix finishing transfers in polling mode by
using common code path and always waiting for the bus to become idle
and disabled.

To support FM+, we mainly need to turn the SMD constant into a parameter
and set it accordingly. That also means we can finally fix SMD to our
needs instead of bailing out. A sanity check for SMD then becomes a
sanity check for 'x == 0'. After all that, activating the enable bit for
FM+ is all we need to do. Tested with a Renesas Falcon board using R-Car

Pull tracing fixes from Steven Rostedt::
"Eventfs fixes:
- With the usage of simple_recursive_remove() recommended by Al Viro,
the code should not be calling "d_invalidate()" itself. Doing so is
causing crashes. The code was calling d_invalidate() on the race of
trying to look up a file while the parent was being deleted. This
was detected, and the added dentry was having d_invalidate() called
on it, but the deletion of the directory was also calling
d_invalidate() on that same dentry.
- A fix to not free the eventfs_inode (ei) until the last dput() was
called on its ei->dentry made the ei->dentry exist even after it
was marked for free by setting the ei->is_freed. But code elsewhere
still was checking if ei->dentry was NULL if ei->is_freed is set
and would trigger WARN_ON if that was the case. That's no longer
true and there should not be any warnings when it is true.
- Use GFP_NOFS for allocations done under eventfs_mutex. The
eventfs_mutex can be taken on file system reclaim, make sure that
allocations done under that mutex do not trigger file system
reclaim.
- Clean up code by moving the taking of inode_lock out of the helper
functions and into where they are needed, and not use the parameter
to know to take it or not. It must always be held but some callers
of the helper function have it taken when they were called.
- Warn if the inode_lock is not held in the helper functions.
- Warn if eventfs_start_creating() is called without a parent. As
eventfs is underneath tracefs, all files created will have a parent
(the top one will have a tracefs parent).

- Add Mathieu Desnoyers as an official reviewer of the tracing subsystem"

Pull arm64 fixes from Catalin Marinas:
- Fix "rodata=on" not disabling "rodata=full" on arm64
- Add arm64 make dependency between vmlinuz.efi and Image, leading to
occasional build failures previously (with parallel building)
- Add newline to the output formatting of the za-fork kselftest
* tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux:

git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip
Pull xen fixes from Juergen Gross:
- A small cleanup patch for the Xen privcmd driver
- A fix for the swiotlb-xen driver which was missing the advertising of
the maximum mapping length
- A fix for Xen on Arm for a longstanding bug, which happened to occur
only recently: a structure in percpu memory crossed a page boundary,
which was rejected by the hypervisor
* tag 'for-linus-6.7a-rc3-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip:
arm/xen: fix xen_vcpu_info allocation alignment
xen: privcmd: Replace zero-length array with flex-array member and use __counted_by
swiotlb-xen: provide the "max_mapping_size" method

Enable GENERIC_BUG_RELATIVE_POINTERS which will store 32-bit relative
offsets to the bug address and the source file name instead of 64-bit
absolute addresses. This effectively reduces the size of the
bug_table[] array by half on 64-bit kernels.

Those return codes are only defined for the parisc architecture and
are leftovers from when we wanted to be HP-UX compatible.
They are not returned by any Linux kernel syscall but do trigger
problems with the glibc strerrorname_np() and strerror() functions as
reported in glibc issue #31080.
There is no need to keep them, so simply remove them.

Make sure that the __bug_table section gets 32- or 64-bit aligned,
depending if a 32- or 64-bit kernel is being built.
Mark it non-writeable and use .blockz instead of the .org assembler
directive to pad the struct.
