The use of an undefined macro in an #if directive is warned, but only
in *.c files. No warning from other files such as *.S, *.lds.S.

Since -Wundef is a preprocessor-related warning, it should be added to
KBUILD_CPPFLAGS instead of KBUILD_CFLAGS.

My previous attempt [1] uncovered several issues. I could not finish
fixing them all.

This commit adds -Wundef to KBUILD_CPPFLAGS for W=1 builds in order to
block new breakages. (The kbuild test robot tests with W=1)

We can fix the warnings one by one. After fixing all of them, we can
make it default in the top Makefile, and remove -Wundef from
KBUILD_CFLAGS.

CONFIG_WERROR turns warnings into errors, which happens only for *.c
files because -Werror is added to KBUILD_CFLAGS.

Adding it to KBUILD_CPPFLAGS makes more sense because preprocessors
understand the -Werror option.

For example, you can put a #warning directive in any preprocessed code.

    warning: #warning "this is a warning message" [-Wcpp]

If -Werror is added, it is promoted to an error.

    error: #warning "this is a warning message" [-Werror=cpp]

This commit moves -Werror to KBUILD_CPPFLAGS so it works in the same way
for *.c, *.S, *.lds.S or whatever needs preprocessing.

Port silent mode detection to the future (post make-4.4) versions of gnu make.

Makefile contains the following piece of make code to detect if option -s is
specified on the command line.

ifneq ($(findstring s,$(filter-out --%,$(MAKEFLAGS))),)

This code is executed by make at parse time and assumes that MAKEFLAGS
does not contain command line variable definitions.
Currently if the user defines a=s on the command line, then at build only
time MAKEFLAGS contains " -- a=s".
However, starting with commit dc2d963989b96161472b2cd38cef5d1f4851ea34
MAKEFLAGS contains command line definitions at both parse time and
build time.

This '-s' detection code then confuses a command line variable
definition which contains letter 's' with option -s.

$ # old make
$ make net/wireless/ocb.o a=s
  CALL    scripts/checksyscalls.sh
  DESCEND objtool
$ # this a new make which defines makeflags at parse time
$ ~/src/gmake/make/l64/make net/wireless/ocb.o a=s
$

We can see here that the letter 's' from 'a=s' was confused with -s.

This patch checks for presence of -s using a method recommended by the
make manual here
https://www.gnu.org/software/make/manual/make.html#Testing-Flags.

If an object is shared among multiple modules, and some of them are
configured as 'm', but the others as 'y', the shared object is built
as modular, then linked to the modules and vmlinux. This is a potential
issue because the expected CFLAGS are different between modules and
builtins.

Commit 637a642f ("zstd: Fixing mixed module-builtin objects")
reported that this could be even more fatal in some cases such as
Clang LTO.

That commit fixed lib/zlib/zstd_{compress,decompress}, but there are
still more instances of breakage.

This commit adds a W=1 warning for shared objects, so that the kbuild
test robot, which provides build tests with W=1, will avoid a new
breakage slipping in.

The flag that tells the event to call its triggers after reading the event
is set for eprobes after the eprobe is enabled. This leads to a race where
the eprobe may be triggered at the beginning of the event where the record
information is NULL. The eprobe then dereferences the NULL record causing
a NULL kernel pointer bug.

Test for a NULL record to keep this from happening.

  cifs: add check for returning value of SMB2_set_info_init

SRS cap is the hardware cap telling if the hardware IOMMU can support
requests seeking supervisor privilege or not. SRE bit in scalable-mode
PASID table entry is treated as Reserved(0) for implementation not
supporting SRS cap.

Checking SRS cap before setting SRE bit can avoid the non-recoverable
fault of "Non-zero reserved field set in PASID Table Entry" caused by
setting SRE bit while there is no SRS cap support. The fault messages
look like below:

 DMAR: DRHD: handling fault status reg 2
 DMAR: [DMA Read NO_PASID] Request device [00:0d.0] fault addr 0x1154e1000
       [fault reason 0x5a]
       SM: Non-zero reserved field set in PASID Table Entry

The A/D bits are preseted for IOVA over first level(FL) usage for both
kernel DMA (i.e, domain typs is IOMMU_DOMAIN_DMA) and user space DMA
usage (i.e., domain type is IOMMU_DOMAIN_UNMANAGED).

Presetting A bit in FL requires to preset the bit in every related paging
entries, including the non-leaf ones. Otherwise, hardware may treat this
as an error. For example, in a case of ECAP_REG.SMPWC==0, DMA faults might
occur with below DMAR fault messages (wrapped for line length) dumped.

 DMAR: DRHD: handling fault status reg 2
 DMAR: [DMA Read NO_PASID] Request device [aa:00.0] fault addr 0x10c3a6000
    [fault reason 0x90]
    SM: A/D bit update needed in first-level entry when set up in no snoop

Pull zonefs fixes from Damien Le Moal:

 - Fix the IO error recovery path for failures happening in the last
   zone of device, and that zone is a "runt" zone (smaller than the
   other zone). The current code was failing to properly obtain a zone
   report in that case.

 - Remove the unused to_attr() function as it is unused, causing
   compilation warnings with clang.

Avoid resetting the module-wide i8042_platform_device pointer in
i8042_probe() or i8042_remove(), so that the device can be properly
destroyed by i8042_exit() on module unload.
