The root cause of panic is the num_pm of nfit_test1 is wrong.
Though 1 is specified for num_pm at nfit_test_init(), it must be 2,
because nfit_test1->spa_set[] array has 2 elements.
Since the array is smaller than expected, the driver breaks other area.
(it is often the link list of devres).
As a result, panic occurs like the following example.

acpi_evaluate_dsm() and friends take a pointer to a raw buffer of 16
bytes. Instead we convert them to use guid_t type. At the same time we
convert current users.
acpi_str_to_uuid() becomes useless after the conversion and it's safe to
get rid of it.

Add a testcase to test kprobes via ftrace interface
with many concurrent kprobe events.
This tries to add many kprobe events (up to 256) on
kernel functions. To avoid making ftrace-based
kprobes (kprobes on fentry), it skips first N bytes
(on x86 N=5, on ppc or arm N=4) of function entry.
After that, it enables all those events, disable it,
and remove it.
Since the unoptimization buffer reclaiming will
be delayed, after removing events, it will wait
enough time.

This patch adds various verifier test cases:
1) A test case for the pruning issue when tracking alignment
is used.
2) Various PTR_TO_MAP_VALUE_OR_NULL tests to make sure pointer
arithmetic turns such register into UNKNOWN_VALUE type.
3) Test cases for the special treatment of LD_ABS/LD_IND to
make sure verifier doesn't break calling convention here.
Latter is needed, since f.e. arm64 JIT uses r1 - r5 for
storing temporary data, so they really must be marked as
NOT_INIT.

The tm-resched-dscr test has started failing sometimes, depending on
what compiler it's built with, eg:
test: tm_resched_dscr
Check DSCR TM context switch: tm-resched-dscr: tm-resched-dscr.c:76: test_body: Assertion `rv' failed.
!! child died by signal 6
When it fails we see that the compiler doesn't initialise rv to 1 before
entering the inline asm block. Although that's counter intuitive, it
is allowed because we tell the compiler that the inline asm will write
to rv (using "=r"), meaning the original value is irrelevant.
Marking it as a read/write parameter would presumably work, but it seems
simpler to fix it by setting the initial value of rv in the inline asm.

Commit 0a5539f66133 ("bpf: Provide a linux/types.h override
for bpf selftests.") caused a build failure for tools/testing/selftest/bpf
because of some missing types:
$ make -C tools/testing/selftests/bpf/

In file included from /home/yhs/work/net-next/tools/testing/selftests/bpf/test_pkt_access.c:8:

static __always_inline __u16 __swab16p(const __u16 *p)
...
The type __aligned_u64 is defined in linux:include/uapi/linux/types.h.
The fix is to copy missing type definition into
tools/testing/selftests/bpf/include/uapi/linux/types.h.
Adding additional include "string.h" resolves __always_inline issue.

With clang/llvm 4.0+, the test case is able to generate

440: (b7) r1 = 15
441: (05) goto pc+73
515: (79) r6 = *(u64 *)(r10 -152)

520: (71) r1 = *(u8 *)(r8 +0)
521: (73) *(u8 *)(r2 +45) = r1
....

Watchdog drivers are not required to retain programming information,
such as timeouts, after the watchdog device is closed. Therefore,
the watchdog test should be able to perform multiple actions after
opening the watchdog device.
For example, to set the timeout to 10s and ping every 5s:
watchdog-test -t 10 -p 5 -e

520: (71) r1 = *(u8 *)(r8 +0)
521: (73) *(u8 *)(r2 +45) = r1
....
and the verifier complains "R2 invalid mem access 'inv'" for insn #521.
This is because verifier marks register r2 as unknown value after #519
where r2 is a stack pointer and r1 holds a constant value.
Teach verifier to recognize "stack_ptr + imm" and
"stack_ptr + reg with const val" as valid stack_ptr with new offset.

To overcome bugs as described and fixed in 89087c456fb5 ("bpf: Fix
values type used in test_maps"), provide a generic BPF_DECLARE_PERCPU()
and bpf_percpu() accessor macro for all percpu map values used in
tests.
Declaring variables works as follows (also works for structs):
BPF_DECLARE_PERCPU(uint32_t, my_value);
They can then be accessed normally as uint32_t type through:
bpf_percpu(my_value, <cpu_nr>)
For example:
bpf_percpu(my_value, 0)++;
Implicitly, we make sure that the passed type is allocated and aligned
by gcc at least on a 8-byte boundary, so that it works together with
the map lookup/update syscall for percpu maps. We use it as a usage
example in test_maps, so that others are free to adapt this into their
code when necessary.

R4=pkt(id=0,off=14,r=14) R5=inv56 R10=fp
This is due to the unconditional ...
#define htons __builtin_bswap16
#define ntohs __builtin_bswap16
... in test_progs that causes this. Make use of asm/byteorder.h
and use __constant_htons() where possible and only perform the

An tracing instance has several of the same capabilities as the top level
instance, but may be implemented slightly different. Instead of just writing
tests that duplicat the same test cases of the top level instance, allow a
test to be written for both the top level as well as for an instance.
If a test case can be run in both the top level as well as in an tracing
instance directory, then it should add a tag "# flags: instance" in the
header of the test file. Then after all tests have run, any test that has an
instance flag set, will run again within a tracing instance.

Maps of per-cpu type have their value element size adjusted to 8 if it
is specified smaller during various map operations.
This makes test_maps as a 32-bit binary fail, in fact the kernel
writes past the end of the value's array on the user's stack.
To be quite honest, I think the kernel should reject creation of a
per-cpu map that doesn't have a value size of at least 8 if that's
what the kernel is going to silently adjust to later.
If the user passed something smaller, it is a sizeof() calcualtion
based upon the type they will actually use (just like in this testcase
code) in later calls to the map operations.

Add napi_id access to __sk_buff for socket filter program types, tc
program types and other bpf_convert_ctx_access() users. Having access
to skb->napi_id is useful for per RX queue listener siloing, f.e.
in combination with SO_ATTACH_REUSEPORT_EBPF and when busy polling is
used, meaning SO_REUSEPORT enabled listeners can then select the
corresponding socket at SYN time already [1]. The skb is marked via
skb_mark_napi_id() early in the receive path (e.g., napi_gro_receive()).
Currently, sockets can only use SO_INCOMING_NAPI_ID from 6d4339028b35
("net: Introduce SO_INCOMING_NAPI_ID") as a socket option to look up
the NAPI ID associated with the queue for steering, which requires a
prior sk_mark_napi_id() after the socket was looked up.
Semantics for the __sk_buff napi_id access are similar, meaning if
skb->napi_id is < MIN_NAPI_ID (e.g. outgoing packets using sender_cpu),
then an invalid napi_id of 0 is returned to the program, otherwise a
valid non-zero napi_id.

The gpio test requires to insert the gpio mockup module (CONFIG_GPIO_MOCKUP).
The gpio mockup driver depends on gpiolib (CONFIG_GPIOLIB).
CONFIG_GPIO_SYSFS is selected automatically by the gpio mockup driver.
Tested on x86_64 and arm64 with defconfig and kselftest-merge.

To build breakpoint_test_arm64, ARCH value is only tested for "aarch64".
It covers only the native build because it's computed from uname -m output.
For cross-compilation, ARCH is set to arm64 and prevent to cross-compile
the test.
Fix the test to allow both native and cross-compilation of the test.
Note: glibc is missing several of the TRAP_* constants in the userspace
definitions. Specifically TRAP_BRANCH and TRAP_HWBKPT.
