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.

Avoid such issue by always mapping the buffer of REPORT ZONES commands
using DMA_BIDIRECTIONAL (read+write IOMMU mapping). This is done by
introducing the helper function _base_scsi_dma_map() and using this helper
in _base_build_sg_scmd() and _base_build_sg_scmd_ieee() instead of calling
directly scsi_dma_map().

This simplifies the min_t() and max_t() macros by no longer making them
work in the context of a C constant expression.
That means that you can no longer use them for static initializers or
for array sizes in type definitions, but there were only a couple of
such uses, and all of them were converted (famous last words) to use
MIN_T/MAX_T instead.

After a recent change in clang to stop consuming all instances of '-S'
and '-c' [1], the stack protector scripts break due to the kernel's use
of -Werror=unused-command-line-argument to catch cases where flags are
not being properly consumed by the compiler driver:
$ echo | clang -o - -x c - -S -c -Werror=unused-command-line-argument
clang: error: argument unused during compilation: '-c' [-Werror,-Wunused-command-line-argument]
This results in CONFIG_STACKPROTECTOR getting disabled because
CONFIG_CC_HAS_SANE_STACKPROTECTOR is no longer set.
'-c' and '-S' both instruct the compiler to stop at different stages of
the pipeline ('-S' after compiling, '-c' after assembling), so having
them present together in the same command makes little sense. In this
case, the test wants to stop before assembling because it is looking at
the textual assembly output of the compiler for either '%fs' or '%gs',
so remove '-c' from the list of arguments to resolve the error.
All versions of GCC continue to work after this change, along with
versions of clang that do or do not contain the change mentioned above.

Commit 3a7e02c040b1 ("minmax: avoid overly complicated constant
expressions in VM code") added the simpler MIN_T/MAX_T macros in order
to avoid some excessive expansion from the rather complicated regular
min/max macros.
The complexity of those macros stems from two issues:
(a) trying to use them in situations that require a C constant
expression (in static initializers and for array sizes)
(b) the type sanity checking
and MIN_T/MAX_T avoids both of these issues.
Now, in the whole (long) discussion about all this, it was pointed out
that the whole type sanity checking is entirely unnecessary for
min_t/max_t which get a fixed type that the comparison is done in.
But that still leaves min_t/max_t unnecessarily complicated due to
worries about the C constant expression case.
However, it turns out that there really aren't very many cases that use
min_t/max_t for this, and we can just force-convert those.
This does exactly that.
Which in turn will then allow for much simpler implementations of
min_t()/max_t(). All the usual "macros in all upper case will evaluate
the arguments multiple times" rules apply.
We should do all the same things for the regular min/max() vs MIN/MAX()
cases, but that has the added complexity of various drivers defining
their own local versions of MIN/MAX, so that needs another level of
fixes first.

UFS link is just put into hibern8 state during the 'freeze' process of the
hibernation. Afterwards, the system may get powered down. But that doesn't
matter during wakeup. Because during wakeup from hibernation, UFS link is
again put into hibern8 state by the restore kernel and then the control is
handed over to the to image kernel.
So in both the places, UFS link is never turned OFF. But
ufshcd_system_restore() just assumes that the link will be in OFF state and
sets the link state accordingly. And this breaks hibernation wakeup:
[ 2445.371335] phy phy-1d87000.phy.3: phy_power_on was called before phy_init
[ 2445.427883] ufshcd-qcom 1d84000.ufshc: Controller enable failed
[ 2445.427890] ufshcd-qcom 1d84000.ufshc: ufshcd_host_reset_and_restore: Host init failed -5
[ 2445.427906] ufs_device_wlun 0:0:0:49488: ufshcd_wl_resume failed: -5
[ 2445.427918] ufs_device_wlun 0:0:0:49488: PM: dpm_run_callback(): scsi_bus_restore returns -5
[ 2445.427973] ufs_device_wlun 0:0:0:49488: PM: failed to restore async: error -5
So fix the issue by removing the code that sets the link to OFF state.
