The reason is due to llvm change https://reviews.llvm.org/D87153
where the CORE relocation global generation is moved from the beginning
of target dependent optimization (llc) to the beginning
of target independent optimization (opt).
Since samples/bpf programs did not use vmlinux.h and its clang compilation
uses native architecture, we need to adjust arch triple at opt level
to do CORE relocation global generation properly. Otherwise, the above
error will appear.
This patch fixed the issue by introduce opt and llvm-dis to compilation chain,
which will do proper CORE relocation global generation as well as O2 level
optimization. Tested with llvm10, llvm11 and trunk/llvm12.

bpf_program__set_attach_target(prog, fd, ...) will always fail when
fd = 0 (attach to a kernel symbol) because obj->btf_vmlinux is NULL

Fix this by using libbpf_find_vmlinux_btf_id().

Say a user reuse map fd after creating a map manually and set the
pin_path, then load the object via libbpf.
In libbpf bpf_object__create_maps(), bpf_object__reuse_map() will
return 0 if there is no pinned map in map->pin_path. Then after
checking if map fd exist, we should also check if pin_path was set
and do bpf_map__pin() instead of continue the loop.
Fix it by creating map if fd not exist and continue checking pin_path
after that.

Previously we forgot to close the map fd if bpf_map_update_elem()
failed during map slot init, which will leak map fd.
Let's move map slot initialization to new function init_map_slots() to
simplify the code. And close the map fd if init slot failed.

Kernel threads intentionally do CLONE_FS in order to follow any changes
that 'init' does to set up the root directory (or cwd).
It is admittedly a bit odd, but it avoids the situation where 'init'
does some extensive setup to initialize the system environment, and then
we execute a usermode helper program, and it uses the original FS setup
from boot time that may be very limited and incomplete.
[ Both Al Viro and Eric Biederman point out that 'pivot_root()' will
follow the root regardless, since it fixes up other users of root (see
chroot_fs_refs() for details), but overmounting root and doing a
chroot() would not. ]
However, Vegard Nossum noticed that the CLONE_FS not only means that we
follow the root and current working directories, it also means we share
umask with whatever init changed it to. That wasn't intentional.
Just reset umask to the original default (0022) before actually starting
the usermode helper program.

Tetsuo Handa reports that splice() can return 0 before the real EOF, if
the data in the splice source pipe is an empty pipe buffer. That empty
pipe buffer case doesn't happen in any normal situation, but you can
trigger it by doing a write to a pipe that fails due to a page fault.
Tetsuo has a test-case to show the behavior:
#define _GNU_SOURCE
#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>
#include <unistd.h>
int main(int argc, char *argv[])
{
const int fd = open("/tmp/testfile", O_WRONLY | O_CREAT, 0600);
int pipe_fd[2] = { -1, -1 };
pipe(pipe_fd);
write(pipe_fd[1], NULL, 4096);
/* This splice() should wait unless interrupted. */
return !splice(pipe_fd[0], NULL, fd, NULL, 65536, 0);
}
which results in
write(5, NULL, 4096) = -1 EFAULT (Bad address)
splice(4, NULL, 3, NULL, 65536, 0) = 0
and this can confuse splice() users into believing they have hit EOF
prematurely.
The issue was introduced when the pipe write code started pre-allocating
the pipe buffers before copying data from user space.
This is modified verion of Tetsuo's original patch.

Fusion adapters can steer completions to individual queues, and
we now have support for shared host-wide tags.
So we can enable multiqueue support for fusion adapters.
Once driver enable shared host-wide tags, cpu hotplug feature is also
supported as it was enabled using below patchsets -
commit bf0beec060 ("blk-mq: drain I/O when all CPUs in a hctx are
offline")
Currently driver has provision to disable host-wide tags using
"host_tagset_enable" module parameter.
Once we do not have any major performance regression using host-wide
tags, we will drop the hand-crafted interrupt affinity settings.
Performance is also meeting the expecatation - (used both none and
mq-deadline scheduler)

So that we don't use a value of 0 for when Scsi_Host.nr_hw_queues is unset,
use the tag_set->nr_hw_queues (which holds 1 for this case).

Add Host and host template flag 'host_tagset' so hostwide tagset can be
shared on multiple reply queues after the SCSI device's reply queue is
converted to blk-mq hw queue.

Currently BUILD_BUG() macro is expanded to smth like the following:
do {
extern void __compiletime_assert_0(void)
__attribute__((error("BUILD_BUG failed")));
if (!(!(1)))
__compiletime_assert_0();
} while (0);
If used in a function body this obviously would produce build errors
with -Wnested-externs and -Werror.
Build objtool with -Wno-nested-externs to enable BUILD_BUG() usage.

Commit 9c34d023dc ("ASoC: omap-mcbsp: Re-arrange files for core McBSP
and Sidetone function split"), in rearranging various files, also replaced
calls to platform_get_resource_by_name() + devm_ioremap_resource() with a
single call to devm_platform_ioremap_resource_byname(). However, the
struct resource is needed as we access its members so at present a null
pointer is dereferenced. Fix by doing things the old way.

We are generating incorrect path in case of rename retry because
we are restarting from wrong dentry. We should restart from the
dentry which was received in the call to nfs_path.

While sst_dsp_get_thread_context() is declared as solution-agnostic, it
is only used by /skylake/ solution. Majority of thread_context field
usages are direct accesses. Improve code cohesiveness and convert to
single usage model.

sound/soc/intel/common/ declares several helper functions for /intel/
solutions. In practice, differences between these - /haswell/ and
/skylake/ especially - led to many of the helpers being used only by a
single solution. As /skylake/ makes no use of these and /haswell/ and
/baytail/ are no more, remove the unused functions.
