Several verifier_private_stack tests failed with latest bpf-next.
For example, for 'Private stack, single prog' subtest, the
jitted code:
func #0:
0: f3 0f 1e fa endbr64
4: 0f 1f 44 00 00 nopl (%rax,%rax)
9: 0f 1f 00 nopl (%rax)
c: 55 pushq %rbp
d: 48 89 e5 movq %rsp, %rbp
10: f3 0f 1e fa endbr64
14: 49 b9 58 74 8a 8f 7d 60 00 00 movabsq $0x607d8f8a7458, %r9
1e: 65 4c 03 0c 25 28 c0 48 87 addq %gs:-0x78b73fd8, %r9
27: bf 2a 00 00 00 movl $0x2a, %edi
2c: 49 89 b9 00 ff ff ff movq %rdi, -0x100(%r9)
33: 31 c0 xorl %eax, %eax
35: c9 leave
36: e9 20 5d 0f e1 jmp 0xffffffffe10f5d5b
The insn 'addq %gs:-0x78b73fd8, %r9' does not match the expected
regex 'addq %gs:0x{{.*}}, %r9' and this caused test failure.
Fix it by changing '%gs:0x{{.*}}' to '%gs:{{.*}}' to accommodate the
possible negative offset. A few other subtests are fixed in a similar way.

Commit [1] moves percpu data on x86 from address 0x000... to address
0xfff...
Before [1]:
159020: 0000000000030700 0 OBJECT GLOBAL DEFAULT 23 pcpu_hot
After [1]:
152602: ffffffff83a3e034 4 OBJECT GLOBAL DEFAULT 35 pcpu_hot
As a result, verifier_bpf_fastcall tests should now expect a negative
value for pcpu_hot, IOW, the disassemble should show "r=" instead of
"w=".
Fix this in the test.
Note that, a later change created a new variable "cpu_number" for
bpf_get_smp_processor_id() [2]. The inlining logic is updated properly
as part of this change, so there is no need to fix anything on the
kernel side.
[1] commit 9d7de2aa8b41 ("x86/percpu/64: Use relative percpu offsets")
[2] commit 01c7bc5198e9 ("x86/smp: Move cpu number to percpu hot section")

The change in struct file [1] moved f_ref to the 3rd cache line.
It made *(u64 *)file dereference invalid from the verifier point of view,
because btf_struct_walk() walks into f_lock field, which is 4-byte long.
Fix the selftests to deference the file pointer as a 4-byte access.

When the cq reservation is failed, the error code is not set which is
initialized to zero in __xsk_generic_xmit(). That means the packet is not
send successfully but sendto() return ok.
Considering the impact on uapi, return -EAGAIN is a good idea. The cq is
full usually because it is not released in time, try to send msg again is
appropriate.
The bug was at the very early implementation of xsk, so the Fixes tag
targets the commit that introduced the changes in
xsk_cq_reserve_addr_locked where this fix depends on.
Fixes: e6c4047f5122 ("xsk: Use xsk_buff_pool directly for cq functions")

Pull x86 TDX updates from Dave Hansen:
"Avoid direct HLT instruction execution in TDX guests.
TDX guests aren't expected to use the HLT instruction directly. It
causes a virtualization exception (#VE). While the #VE _can_ be
handled, the current handling is slow and buggy and the easiest thing
is just to avoid HLT in the first place. Plus, the kernel already has
paravirt infrastructure that makes it relatively painless.
Make TDX guests require paravirt and add some TDX-specific paravirt
handlers which avoid HLT in the normal halt routines. Also add a
warning in case another HLT sneaks in.
There was a report that this leads to a "major performance
improvement" on specjbb2015, probably because of the extra #VE
overhead or missed wakeups from the buggy HLT handling"

Some architectures do not have data cache coherency between user and
kernel space. For these architectures, the cache needs to be flushed on
both the kernel and user addresses so that user space can see the updates
the kernel has made.
Instead of using flush_dcache_folio() and playing with virt_to_folio()
within the call to that function, use flush_kernel_vmap_range() which
takes the virtual address and does the work for those architectures that
need it.
This also fixes a bug where the flush of the reader page only flushed one
page. If the sub-buffer order is 1 or more, where the sub-buffer size
would be greater than a page, it would miss the rest of the sub-buffer
content, as the "reader page" is not just a page, but the size of a
sub-buffer.

The code to map the physical memory retrieved by memmap currently
allocates an array of pages to cover the physical memory and then calls
vmap() to map it to a virtual address. Instead of using this temporary
array of struct page descriptors, simply use vmap_page_range() that can
directly map the contiguous physical memory to a virtual address.

The reserve_mem kernel command line option may pass back a physical
address, but the memory is still part of the normal memory just like
using memblock_alloc() would be. This means that the physical memory
returned by the reserve_mem command line option can be converted directly
to virtual memory by simply using phys_to_virt().
When freeing the buffer there's no need to call vunmap() anymore as the
memory allocated by reserve_mem is freed by the call to
reserve_mem_release_by_name().
Because the persistent ring buffer can also be allocated via the memmap
option, which *is* different than normal memory as it cannot be added back
to the buddy system, it must be treated differently. It still needs to be
virtually mapped to have access to it. It also can not be freed nor can it
ever be memory mapped to user space.
Create a new trace_array flag called TRACE_ARRAY_FL_MEMMAP which gets set
if the buffer is created by the memmap option, and this will prevent the
buffer from being memory mapped by user space.
Also increment the ref count for memmap'ed buffers so that they can never
be freed.

Kernel cross-compilation with BUILDTIME_MCOUNT_SORT produces zeroed
mcount values if the build-host endianness does not match the ELF
file endianness.
The mcount values array is converted from ELF file
endianness to build-host endianness during initialization in
fill_relocs()/fill_addrs(). Avoid extra conversion of these values during
weak-function zeroing; otherwise, they do not match nm-parsed addresses
and all mcount values are zeroed out.

The trace event verifier checks the formats of trace events to make sure
that they do not point at memory that is not in the trace event itself or
in data that will never be freed. If an event references data that was
allocated when the event triggered and that same data is freed before the
event is read, then the kernel can crash by reading freed memory.
The verifier runs at boot up (or module load) and scans the print formats
of the events and checks their arguments to make sure that dereferenced
pointers are safe. If the format uses "%*p.." the verifier will ignore it,
and that could be dangerous. Cover this case as well.
Also add to the sample code a use case of "%*pbl".
