Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.

If the caller supplies an iocb->ki_pos value that is close to the
filesystem upper limit, and an iterator with a count that causes us to
overflow that limit, then filemap_read() enters an infinite loop.
This behaviour was discovered when testing xfstests generic/525 with the
"localio" optimisation for loopback NFS mounts.

i2c-host fixes for v6.12-rc7
In designware an incorrect behavior has been fixes when
concluding a transmission.
Fixed return error value evaluation in the Mule multiplexer.
CONFIG_CLK_KUNIT_TEST=y, CONFIG_DEBUG_KMEMLEAK=y
and CONFIG_DEBUG_KMEMLEAK_AUTO_SCAN=y, the following memory leak occurs.
If the KUNIT_ASSERT_*() fails, the latter (exit() or testcases)
clk_put() or clk_hw_unregister() will fail to release the clk resource
and cause memory leaks, use new clk_hw_register_kunit()
and clk_hw_get_clk_kunit() to automatically release them.

Allowing these GDSCs to collapse makes the QMP combo PHYs lose their
configuration on machine suspend. Currently, the QMP combo PHY driver
doesn't reinitialise the HW on resume. Under such conditions, the USB
SuperSpeed support is broken. To avoid this, mark the pwrsts flags with
RET_ON. This has been already done for USB 0 and 1 SS PHY GDSCs,
Do this also for the USB MP SS1 PHY GDSC config. The USB MP SS0 PHY GDSC
already has it.

When the Tx FIFO is empty and the last command has no STOP bit
set, the master holds SCL low. If I2C_DYNAMIC_TAR_UPDATE is not
set, BIT(13) MST_ON_HOLD of IC_RAW_INTR_STAT is not enabled,
causing the __i2c_dw_disable() timeout. This is quite similar to
commit 2409205acd3c ("i2c: designware: fix __i2c_dw_disable() in

MST_HOLD_TX_FIFO_EMPTY in IC_STATUS, which is available when
IC_STAT_FOR_CLK_STRETCH is set.

The pipediv2_clk's source from the same mux as pipe clock. So they have
same limitation, which is that the PHY sequence requires to enable these
local CBCs before the PHY is actually outputting a clock to them. This
means the clock won't actually turn on when we vote them. Hence, let's
skip the halt bit check of the pipediv2_clk, otherwise pipediv2_clk may
stuck at off state during bootup.

Christoffer reports that on some implementations, writing to
GICR_ISACTIVER0 (and similar GICD registers) can race badly with a guest
issuing a deactivation of that interrupt via the system register interface.
There are multiple reasons to this:
- this uses an early write-acknoledgement memory type (nGnRE), meaning
that the write may only have made it as far as some interconnect
by the time the store is considered "done"
- the GIC itself is allowed to buffer the write until it decides to
take it into account (as long as it is in finite time)
The effects are that the activation may not have taken effect by the time
the kernel enters the guest, forcing an immediate exit, or that a guest
deactivation occurs before the interrupt is active, doing nothing.
In order to guarantee that the write to the ISACTIVER register has taken
effect, read back from it, forcing the interconnect to propagate the write,
and the GIC to process the write before returning the read.
