spi-geni-qcom: Add new interfaces and utilise them

Merge series from Vijaya Krishna Nivarthi <quic_vnivarth@quicinc.com>:

A "known issue" during implementation of SE DMA for spi geni driver was
that it does DMA map/unmap internally instead of in spi framework.
Current patches remove this hiccup and also clean up code a bit.

Testing revealed no regressions and results with 1000 iterations of
reading from EC showed no loss of performance.

perf tools fixes for v6.4: 2nd batch

- Fix BPF CO-RE naming convention for checking the availability of fields on
'union perf_mem_data_src' on the running kernel.

- Remove the use of llvm-strip on BPF skel object files, not needed, fixes a
build breakage when the llvm package, that contains it in most distros, isn't
installed.

- Fix tools that use both evsel->{bpf_counter_list,bpf_filters}, removing them from a
union.

- Remove extra "--" from the 'perf ftrace latency' --use-nsec option,
previously it was working only when using the '-n' alternative.

- Don't stop building when both binutils-devel and a C++ compiler isn't
available to compile the alternative C++ demangle support code, disable that
feature instead.

- Sync the linux/in.h and coresight-pmu.h header copies with the kernel sources.

- Fix relative include path to cs-etm.h.

erofs: fix null-ptr-deref caused by erofs_xattr_prefixes_init

Fragments and dedupe share one feature bit, and thus packed inode may not
exist when fragment feature bit (dedupe feature bit exactly) is set, e.g.
when deduplication feature is in use while fragments feature is not. In
this case, sbi->packed_inode could be NULL while fragments feature bit
is set.

Fix this by accessing packed inode only when it exists.

Pull erofs updates from Gao Xiang:
"In this cycle, sub-page block support for uncompressed files is
available. It's mainly used to enable original signing ('golden')
4k-block images on arm64 with 16/64k pages. In addition, end users
could also use this feature to build a manifest to directly refer to
golden tar data.

Besides, long xattr name prefix support is also introduced in this
cycle to avoid too many xattrs with the same prefix (e.g. overlayfs
xattrs). It's useful for erofs + overlayfs combination (like Composefs
model): the image size is reduced by ~14% and runtime performance is
also slightly improved.

Others are random fixes and cleanups as usual.

Summary:

- Add sub-page block size support for uncompressed files

- Support flattened block device for multi-blob images to be attached
into virtual machines (including cloud servers) and bare metals

- Support long xattr name prefixes to optimize images with common
xattr namespaces (e.g. files with overlayfs xattrs) use cases

- Various minor cleanups & fixes"

Merge tag 'v6.4/vfs.acl' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs

Pull acl updates from Christian Brauner:
"After finishing the introduction of the new posix acl api last cycle
the generic POSIX ACL xattr handlers are still around in the
filesystems xattr handlers for two reasons:

(1) Because a few filesystems rely on the ->list() method of the
generic POSIX ACL xattr handlers in their ->listxattr() inode
operation.

(2) POSIX ACLs are only available if IOP_XATTR is raised. The
IOP_XATTR flag is raised in inode_init_always() based on whether
the sb->s_xattr pointer is non-NULL. IOW, the registered xattr
handlers of the filesystem are used to raise IOP_XATTR. Removing
the generic POSIX ACL xattr handlers from all filesystems would
risk regressing filesystems that only implement POSIX ACL support
and no other xattrs (nfs3 comes to mind).

This contains the work to decouple POSIX ACLs from the IOP_XATTR flag
as they don't depend on xattr handlers anymore. So it's now possible
to remove the generic POSIX ACL xattr handlers from the sb->s_xattr
list of all filesystems. This is a crucial step as the generic POSIX
ACL xattr handlers aren't used for POSIX ACLs anymore and POSIX ACLs
don't depend on the xattr infrastructure anymore.

Adressing problem (1) will require more long-term work. It would be
best to get rid of the ->list() method of xattr handlers completely at
some point.

For erofs, ext{2,4}, f2fs, jffs2, ocfs2, and reiserfs the nop POSIX
ACL xattr handler is kept around so they can continue to use
array-based xattr handler indexing.

This update does simplify the ->listxattr() implementation of all
these filesystems however"

erofs: avoid hardcoded blocksize for subpage block support

As the first step of converting hardcoded blocksize to that specified in
on-disk superblock, convert all call sites of hardcoded blocksize to
sb->s_blocksize except for:

1) use sbi->blkszbits instead of sb->s_blocksize in
erofs_superblock_csum_verify() since sb->s_blocksize has not been
updated with the on-disk blocksize yet when the function is called.

2) use inode->i_blkbits instead of sb->s_blocksize in erofs_bread(),
since the inode operated on may be an anonymous inode in fscache mode.
Currently the anonymous inode is allocated from an anonymous mount
maintained in erofs, while in the near future we may allocate anonymous
inodes from a generic API directly and thus have no access to the
anonymous inode's i_sb. Thus we keep the block size in i_blkbits for
anonymous inodes in fscache mode.

Be noted that this patch only gets rid of the hardcoded blocksize, in
preparation for actually setting the on-disk block size in the following
patch. The hard limit of constraining the block size to PAGE_SIZE still
exists until the next patch.
