commit 0ac417b8f124427c90ec8c2ef4f632b821d924cc upstream.
Q7_THRM# pin is connected to a diode on the module which is used
as a level shifter, and the pin have a pull-down enabled by
default. We need to configure it to internal pull-up, other-
wise whenever the pin is configured as INPUT and we try to
control it externally the value will always remain zero.

[ Upstream commit 61231eb8113ce47991f35024f9c20810b37996bf ]
"gmac" node stands for just an ordinary Ethernet controller,
which is by no means a provider of interrupts, i.e. it doesn't serve
as an interrupt controller, thus "#interrupt-cells" property doesn't
belong to it and so we remove it.

[ Upstream commit 945a7c8570916650a415757d15d83e0fa856a686 ]
The PCIE_WAKE# has a diode used as a level-shifter, and is used as an
input pin. While the SoC default is to enable the pull-up, the core
rk3399 pinconf for this pin opted for pull-none. So as to not disturb
the behaviour of other boards which may rely on pull-none instead of
pull-up, set the needed pull-up only for RK3399 Puma.

[ Upstream commit 9543f6e26634537997b6e909c20911b7bf4876de ]
Fix cpuid_deps[] to list the correct dependencies for GFNI, VAES, and
VPCLMULQDQ. These features don't depend on AVX512, and there exist CPUs
that support these features but not AVX512. GFNI actually doesn't even
depend on AVX.
This prevents GFNI from being unnecessarily disabled if AVX is disabled
to mitigate the GDS vulnerability.
This also prevents all three features from being unnecessarily disabled
if AVX512VL (or its dependency AVX512F) were to be disabled, but it
looks like there isn't any case where this happens anyway.

commit 5ce344beaca688f4cdea07045e0b8f03dc537e74 upstream.
When done from a virtual machine, instructions that touch APIC memory
must be emulated. By convention, MMIO accesses are typically performed
via io.h helpers such as readl() or writeq() to simplify instruction
emulation/decoding (ex: in KVM hosts and SEV guests) [0].
Currently, native_apic_mem_read() does not follow this convention,
allowing the compiler to emit instructions other than the MOV
instruction generated by readl(). In particular, when the kernel is
compiled with clang and run as a SEV-ES or SEV-SNP guest, the compiler
would emit a TESTL instruction which is not supported by the SEV-ES
emulator, causing a boot failure in that environment. It is likely the
same problem would happen in a TDX guest as that uses the same
instruction emulator as SEV-ES.
To make sure all emulators can emulate APIC memory reads via MOV, use
the readl() function in native_apic_mem_read(). It is expected that any
emulator would support MOV in any addressing mode as it is the most
generic and is what is usually emitted currently.
The TESTL instruction is emitted when native_apic_mem_read() is inlined
into apic_mem_wait_icr_idle(). The emulator comes from
insn_decode_mmio() in arch/x86/lib/insn-eval.c. It's not worth it to
extend insn_decode_mmio() to support more instructions since, in theory,
the compiler could choose to output nearly any instruction for such
reads which would bloat the emulator beyond reason.

commit abee7c494d8c41bb388839bccc47e06247f0d7de upstream.
When running in lazy TLB mode the currently active page tables might
be the ones of a previous process, e.g. when running a kernel thread.
This can be problematic in case kernel code is being modified via
text_poke() in a kernel thread, and on another processor exit_mmap()
is active for the process which was running on the first cpu before
the kernel thread.
As text_poke() is using a temporary address space and the former
address space (obtained via cpu_tlbstate.loaded_mm) is restored
afterwards, there is a race possible in case the cpu on which
exit_mmap() is running wants to make sure there are no stale
references to that address space on any cpu active (this e.g. is
required when running as a Xen PV guest, where this problem has been
observed and analyzed).
In order to avoid that, drop off TLB lazy mode before switching to the
temporary address space.

commit 04c35ab3bdae7fefbd7c7a7355f29fa03a035221 upstream.
PAT handling won't do the right thing in COW mappings: the first PTE (or,
in fact, all PTEs) can be replaced during write faults to point at anon
folios. Reliably recovering the correct PFN and cachemode using
follow_phys() from PTEs will not work in COW mappings.
Using follow_phys(), we might just get the address+protection of the anon
folio (which is very wrong), or fail on swap/nonswap entries, failing
follow_phys() and triggering a WARN_ON_ONCE() in untrack_pfn() and
track_pfn_copy(), not properly calling free_pfn_range().
In free_pfn_range(), we either wouldn't call memtype_free() or would call
it with the wrong range, possibly leaking memory.
To fix that, let's update follow_phys() to refuse returning anon folios,
and fallback to using the stored PFN inside vma->vm_pgoff for COW mappings
if we run into that.
We will now properly handle untrack_pfn() with COW mappings, where we
don't need the cachemode. We'll have to fail fork()->track_pfn_copy() if
the first page was replaced by an anon folio, though: we'd have to store
the cachemode in the VMA to make this work, likely growing the VMA size.
For now, lets keep it simple and let track_pfn_copy() just fail in that
case: it would have failed in the past with swap/nonswap entries already,
and it would have done the wrong thing with anon folios.
Simple reproducer to trigger the WARN_ON_ONCE() in untrack_pfn():

commit 3ddf944b32f88741c303f0b21459dbb3872b8bc5 upstream.

...
sysfs nodes by writing the new bit mask of events to enable.
When the write is accepted, the kernel deletes all current timers and
reinits all banks.
Doing that in parallel can lead to initializing a timer which is already
armed and in the timer wheel, i.e., in use already:
ODEBUG: init active (active state 0) object: ffff888063a28000 object
type: timer_list hint: mce_timer_fn+0x0/0x240 arch/x86/kernel/cpu/mce/core.c:2642
WARNING: CPU: 0 PID: 8120 at lib/debugobjects.c:514
debug_print_object+0x1a0/0x2a0 lib/debugobjects.c:514
Fix that by grabbing the sysfs mutex as the rest of the MCA sysfs code
does.

commit c567f2948f57bdc03ed03403ae0234085f376b7d upstream.
This reverts commit d794734c9bbfe22f86686dc2909c25f5ffe1a572.
While the original change tries to fix a bug, it also unintentionally broke
existing systems, see the regressions reported at:
https://lore.kernel.org/all/3a1b9909-45ac-4f97-ad68-d16ef1ce99db@pavinjoseph.com/
Since d794734c9bbf was also marked for -stable, let's back it out before
causing more damage.
Note that due to another upstream change the revert was not 100% automatic:

commit 35f20786c481d5ced9283ff42de5c69b65e5ed13 upstream.
arch/powerpc/lib/xor_vmx.o is built with '-msoft-float' (from the main
powerpc Makefile) and '-maltivec' (from its CFLAGS), which causes an
error when building with clang after a recent change in main:
error: option '-msoft-float' cannot be specified with '-maltivec'
make[6]: *** [scripts/Makefile.build:243: arch/powerpc/lib/xor_vmx.o] Error 1
Explicitly add '-mhard-float' before '-maltivec' in xor_vmx.o's CFLAGS
to override the previous inclusion of '-msoft-float' (as the last option
wins), which matches how other areas of the kernel use '-maltivec', such
as AMDGPU.

[ Upstream commit 5f491356b7149564ab22323ccce79c8d595bfd0c ]
Binutils 2.38 complains about the use of mfpmr when building
ppc6xx_defconfig:
CC arch/powerpc/kernel/pmc.o
{standard input}: Assembler messages:
{standard input}:45: Error: unrecognized opcode: `mfpmr'
{standard input}:56: Error: unrecognized opcode: `mtpmr'
This is because by default the kernel is built with -mcpu=powerpc, and
the mt/mfpmr instructions are not defined.
It can be avoided by enabling CONFIG_E300C3_CPU, but just adding that to
the defconfig will leave open the possibility of randconfig failures.
So add machine directives around the mt/mfpmr instructions to tell
binutils how to assemble them.

[ Upstream commit 0568b6f0d863643db2edcc7be31165740c89fa82 ]
IPv6 checksum tests with unaligned addresses on 64-bit builds result
in unexpected failures.
Expected expected == csum_result, but
expected == 46591 (0xb5ff)
csum_result == 46381 (0xb52d)
with alignment offset 1
Oddly enough, the problem disappeared after adding test code into
the beginning of csum_ipv6_magic().
As it turns out, the 'sum' parameter of csum_ipv6_magic() is declared as
__wsum, which is a 32-bit variable. However, it is treated as 64-bit
variable in the 64-bit assembler code. Tests showed that the upper 32 bit
of the register used to pass the variable are _not_ cleared when entering
the function. This can result in checksum calculation errors.
Clearing the upper 32 bit of 'sum' as first operation in the assembler
code fixes the problem.

[ Upstream commit 4b75b12d70506e31fc02356bbca60f8d5ca012d0 ]
hppa 64-bit systems calculates the IPv6 checksum using 64-bit add
operations. The last add folds protocol and length fields into the 64-bit
result. While unlikely, this operation can overflow. The overflow can be
triggered with a code sequence such as the following.
/* try to trigger massive overflows */
memset(tmp_buf, 0xff, sizeof(struct in6_addr));
csum_result = csum_ipv6_magic((struct in6_addr *)tmp_buf,
(struct in6_addr *)tmp_buf,
0xffff, 0xff, 0xffffffff);
Fix the problem by adding any overflows from the final add operation into
the calculated checksum. Fortunately, we can do this without additional
cost by replacing the add operation used to fold the checksum into 32 bit
with "add,dc" to add in the missing carry.

[ Upstream commit 4408ba75e4ba80c91fde7e10bccccf388f5c09be ]
Calculating the IPv6 checksum on 32-bit systems missed overflows when
adding the proto+len fields into the checksum. This results in the
following unit test failure.
# test_csum_ipv6_magic: ASSERTION FAILED at lib/checksum_kunit.c:506
Expected ( u64)csum_result == ( u64)expected, but
( u64)csum_result == 46722 (0xb682)
( u64)expected == 46721 (0xb681)
not ok 5 test_csum_ipv6_magic
This is probably rarely seen in the real world because proto+len are
usually small values which will rarely result in overflows when calculating
the checksum. However, the unit test code uses large values for the length
field, causing the test to fail.
Fix the problem by adding the missing carry into the final checksum.

[ Upstream commit a2abae8f0b638c31bb9799d9dd847306e0d005bd ]
IP checksum unit tests report the following error when run on hppa/hppa64.
# test_ip_fast_csum: ASSERTION FAILED at lib/checksum_kunit.c:463
Expected ( u64)csum_result == ( u64)expected, but
( u64)csum_result == 33754 (0x83da)
( u64)expected == 10946 (0x2ac2)
not ok 4 test_ip_fast_csum
0x83da is the expected result if the IP header length is 20 bytes. 0x2ac2
is the expected result if the IP header length is 24 bytes. The test fails
with an IP header length of 24 bytes. It appears that ip_fast_csum()
always returns the checksum for a 20-byte header, no matter how long
the header actually is.
Code analysis shows a suspicious assembler sequence in ip_fast_csum().
" addc %0, %3, %0\n"
"1: ldws,ma 4(%1), %3\n"
" addib,< 0, %2, 1b\n" <---
While my understanding of HPPA assembler is limited, it does not seem
to make much sense to subtract 0 from a register and to expect the result
to ever be negative. Subtracting 1 from the length parameter makes more
sense. On top of that, the operation should be repeated if and only if
the result is still > 0, so change the suspicious instruction to
" addib,> -1, %2, 1b\n"
The IP checksum unit test passes after this change.

commit e7862eda309ecfccc36bb5558d937ed3ace07f3f upstream.
The AMD Zen4 core supports a new feature called Automatic IBRS.
It is a "set-and-forget" feature that means that, like Intel's Enhanced IBRS,
h/w manages its IBRS mitigation resources automatically across CPL transitions.
The feature is advertised by CPUID_Fn80000021_EAX bit 8 and is enabled by
setting MSR C000_0080 (EFER) bit 21.
Enable Automatic IBRS by default if the CPU feature is present. It typically
provides greater performance over the incumbent generic retpolines mitigation.
Reuse the SPECTRE_V2_EIBRS spectre_v2_mitigation enum. AMD Automatic IBRS and
Intel Enhanced IBRS have similar enablement. Add NO_EIBRS_PBRSB to
cpu_vuln_whitelist, since AMD Automatic IBRS isn't affected by PBRSB-eIBRS.
The kernel command line option spectre_v2=eibrs is used to select AMD Automatic
IBRS, if available.

[ Upstream commit 23e85be1ec81647374055f731488cc9a7c013a5c ]
Add regulator nodes vcc-dram and vcc1v2 to the devicetree. These
regulators correspond to U4 and U5 in the schematics:

[ Upstream commit 367c50f78451d3bd7ad70bc5c89f9ba6dec46ca9 ]
Current average steal timer calculation produces volatile and inflated
values. The only user of this value is KVM so far and it uses that to
decide whether or not to yield the vCPU which is seeing steal time.
KVM compares average steal timer to a threshold and if the threshold
is past then it does not allow CPU polling and yields it to host, else
it keeps the CPU by polling.
Since KVM's steal time threshold is very low by default (%10) it most
likely is not effected much by the bloated average steal timer values
because the operating region is pretty small. However there might be
new users in the future who might rely on this number. Fix average
steal timer calculation by changing the formula from:
avg_steal_timer = avg_steal_timer / 2 + steal_timer;
to the following:
avg_steal_timer = (avg_steal_timer + steal_timer) / 2;
This ensures that avg_steal_timer is actually a naive average of steal
timer values. It now closely follows steal timer values but of course
in a smoother manner.

Running event hv_gpci/dispatch_timebase_by_processor_processor_time_in_timebase_cycles,phys_processor_idx=0/

The above error is because of the hcall failure as required
permission "Enable Performance Information Collection" is not set.
Based on current code, single_gpci_request function did not check the
error type incase hcall fails and by default returns EINVAL. But we can
have other reasons for hcall failures like H_AUTHORITY/H_PARAMETER with
detail_rc as GEN_BUF_TOO_SMALL, for which we need to act accordingly.
Fix this issue by adding new checks in the single_gpci_request and
h_gpci_event_init functions.
Result after fix patch changes:
# perf stat -e hv_gpci/dispatch_timebase_by_processor_processor_time_in_timebase_cycles,phys_processor_idx=0/ sleep 2
