NEW_ADDR blocks are purely in-memory preallocated blocks, and thus
equivalent to what the core FS code calls delayed allocations, and not
unwritten extents which do have on-disk blocks allocated from which
reads always return zeroes until they are converted to written status.

When testing with a mixed zoned / convention device combination, there
are regular but not 100% reproducible failures in xfstests generic/113
where the __is_valid_data_blkaddr assert hits due to finding a hole.
This seems to be because f2fs_map_blocks can set this flag on a hole
when it was found in the extent cache.
Rework f2fs_iomap_begin to just check the special block numbers directly.
This has the added benefits of the WARN_ON showing which invalid block
address we found, and being properly error out on delalloc blocks that
are confusingly called unwritten but not actually suitable for direct
I/O.

to call clear_page_private_reference() in .{release,invalid}_folio,

With below two cases, it will cause NULL pointer dereference when
accessing SM_I(sbi)->fcc_info in f2fs_issue_flush().
a) If kthread_run() fails in f2fs_create_flush_cmd_control(), it will
release SM_I(sbi)->fcc_info,
- mount -o noflush_merge /dev/vda /mnt/f2fs
- mount -o remount,flush_merge /dev/vda /mnt/f2fs -- kthread_run() fails
- dd if=/dev/zero of=/mnt/f2fs/file bs=4k count=1 conv=fsync
b) we will never allocate memory for SM_I(sbi)->fcc_info w/ below
testcase,
- mount -o ro /dev/vda /mnt/f2fs
- mount -o rw,remount /dev/vda /mnt/f2fs
- dd if=/dev/zero of=/mnt/f2fs/file bs=4k count=1 conv=fsync
In order to fix this issue, let change as below:
- fix error path handling in f2fs_create_flush_cmd_control().
- allocate SM_I(sbi)->fcc_info even if readonly is on.

syzbot is reporting hung task at do_user_addr_fault() [1], for there is
a silent deadlock between PG_locked bit and ni_lock lock.
Since filemap_update_page() calls filemap_read_folio() after calling
folio_trylock() which will set PG_locked bit, ntfs_truncate() must not
call truncate_setsize() which will wait for PG_locked bit to be cleared
when holding ni_lock lock.

freeing image->elf_headers in the error path of crash_load_segments()

If v4 READDIR operation hits a mountpoint and gets back an error,
then it will include that entry in the reply and set RDATTR_ERROR for it
to the error.
That's fine for "normal" exported filesystems, but on the v4root, we
need to be more careful to only expose the existence of dentries that
lead to exports.
If the mountd upcall times out while checking to see whether a
mountpoint on the v4root is exported, then we have no recourse other
than to fail the whole operation.

Starting from ICL, the default for MIPI GPIO sequences seems to be using
native GPIOs i.e. GPIOs available in the GPU. These native GPIOs reuse
many pins that quite frankly seem scary to poke based on the VBT
sequences. We pretty much have to trust that the board is configured
such that the relevant HPD, PP_CONTROL and GPIO bits aren't used for
anything else.
MIPI sequence v4 also adds a flag to fall back to non-native sequences.
v5:
- Wrap SHOTPLUG_CTL_DDI modification in spin_lock() in icp_irq_handler()
too (Ville)
- References instead of Closes issue 6131 because this does not fix everything
v4:
- Wrap SHOTPLUG_CTL_DDI modification in spin_lock_irq() (Ville)
v3:
- Fix -Wbitwise-conditional-parentheses (kernel test robot <lkp@intel.com>)
v2:
- Fix HPD pin output set (impacts GPIOs 0 and 5)
- Fix GPIO data output direction set (impacts GPIOs 4 and 9)
- Reduce register accesses to single intel_de_rwm()

Guoqing Jiang reports that openSUSE cannot compile the kernel rpm due
to "BuildRequires: elfutils-libelf-devel" added by commit 8818039f959b
("kbuild: add ability to make source rpm buildable using koji").
The relevant package name in openSUSE is libelf-devel.
Add it as an alternative package.
BTW, if it is impossible to solve the build requirement, the final
resort would be:
$ make RPMOPTS=--nodeps rpm-pkg
This passes --nodeps to the rpmbuild command so it will not verify
build dependencies. This is useful to test rpm builds on non-rpm
system. On Debian/Ubuntu, for example, you can install rpmbuild by
'apt-get install rpm'.
NOTE1:
Likewise, it is possible to bypass the build dependency check for
debian package builds:
$ make DPKG_FLAGS=-d deb-pkg
NOTE2:
The 'or' operator is supported since RPM 4.13. So, old distros such
as CentOS 7 will break. I suggest installing newer rpmbuild in such
cases.

commit 3d57e1b7b1d4 ("kbuild: refactor the prerequisites of the modpost
rule") moved 'vmlinux.o' inside modpost-args, possibly before some of
the other options. However, getopt() in musl libc follows POSIX and
stops looking for options upon reaching the first non-option argument.
As a result, the '-T' option is misinterpreted as a positional argument,
and the build fails:
make -f ./scripts/Makefile.modpost
scripts/mod/modpost -E -o Module.symvers vmlinux.o -T modules.order
-T: No such file or directory
make[1]: *** [scripts/Makefile.modpost:137: Module.symvers] Error 1
make: *** [Makefile:1960: modpost] Error 2
The fix is to move all options before 'vmlinux.o' in modpost-args.

Previously, *.rpm files were created under $HOME/rpmbuild/, but since
commit 8818039f959b ("kbuild: add ability to make source rpm buildable
using koji"), srcrpm-pkg creates the source rpm in the kernel tree
because it sets '_srcrpmdir'.

Dennis Gilmore reports that the BuildID is missing in the arm64 vmlinux
since commit 994b7ac1697b ("arm64: remove special treatment for the
link order of head.o").
The issue is that the type of .notes section, which contains the BuildID,
changed from NOTES to PROGBITS.
Ard Biesheuvel figured out that whichever object gets linked first gets
to decide the type of a section. The PROGBITS type is the result of the
compiler emitting .note.GNU-stack as PROGBITS rather than NOTE.
While Ard provided a fix for arm64, I want to fix this globally because
the same issue is happening on riscv since commit 2348e6bf4421 ("riscv:
remove special treatment for the link order of head.o"). This problem
will happen in general for other architectures if they start to drop
unneeded entries from scripts/head-object-list.txt.
Discard .note.GNU-stack in include/asm-generic/vmlinux.lds.h.

In the case where a firmware file is too large (e.g. someone
downloaded a web page ASCII dump from github...), the firmware object
is released but the pointer is not zerod. If no other firmware file
was found then release would be called again leading to a double kfree.
Also, the size check was only being applied to the initial firmware
load not any of the subsequent attempts. So move the check into a
wrapper that is used for all loads.

The catch-all evict can fail due to object lock contention, since it
only goes as far as trylocking the object, due to us already holding the
vm->mutex. Doing a full object lock here can deadlock, since the
vm->mutex is always our inner lock. Add another execbuf pass which drops
the vm->mutex and then tries to grab the object will the full lock,
before then retrying the eviction. This should be good enough for now to
fix the immediate regression with userspace seeing -ENOSPC from execbuf
due to contended object locks during GTT eviction.
v2 (Mani)
- Also revamp the docs for the different passes.

The attribute __maybe_unused should remain only until the respective
info is not in the pciidlist. The info can't be added together
with its definition because that would cause the driver to automatically
probe for the device, while it's still not ready for that. However once
pciidlist contains it, the attribute can be removed.
