commit dfe6d190f38fc5df5ff2614b463a5195a399c885 upstream.
It appears that we don't allow a vcpu to be restored in AArch32
System mode, as we *never* included it in the list of valid modes.
Just add it to the list of allowed modes.

commit 428a575dc9038846ad259466d5ba109858c0a023 upstream.
During boot, Linux kernel complains:
[ 0.000000] GIC: GICv2 detected, but range too small and irqchip.gicv2_force_probe not set
This SoC is using a regular GIC-400 and the GICR space size should be
8KB rather than 256B.
With this patch:
[ 0.000000] GIC: Using split EOI/Deactivate mode
So this should be the correct fix.

commit 2633c58e1354d7de2c8e7be8bdb6f68a0a01bad7 upstream.
There is no such device as "as3722@40", because its name is "pmic". Use
phandles for aliases to fix relying on full node path. This corrects
aliases for RTC devices and also fixes dtc W=1 warning:

[ Upstream commit ffbf4fb9b5c12ff878a10ea17997147ea4ebea6f ]
When CONFIG_DEBUG_BUGVERBOSE=n, we fail to add necessary padding bytes
to bug_table entries, and as a result the last entry in a bug table will
be ignored, potentially leading to an unexpected panic(). All prior
entries in the table will be handled correctly.
The arm64 ABI requires that struct fields of up to 8 bytes are
naturally-aligned, with padding added within a struct such that struct
are suitably aligned within arrays.
When CONFIG_DEBUG_BUGVERPOSE=y, the layout of a bug_entry is:
struct bug_entry {
signed int bug_addr_disp; // 4 bytes
signed int file_disp; // 4 bytes
unsigned short line; // 2 bytes
unsigned short flags; // 2 bytes
}
... with 12 bytes total, requiring 4-byte alignment.
When CONFIG_DEBUG_BUGVERBOSE=n, the layout of a bug_entry is:
struct bug_entry {
signed int bug_addr_disp; // 4 bytes
unsigned short flags; // 2 bytes
< implicit padding > // 2 bytes
}
... with 8 bytes total, with 6 bytes of data and 2 bytes of trailing
padding, requiring 4-byte alginment.
When we create a bug_entry in assembly, we align the start of the entry
to 4 bytes, which implicitly handles padding for any prior entries.
However, we do not align the end of the entry, and so when
CONFIG_DEBUG_BUGVERBOSE=n, the final entry lacks the trailing padding
bytes.
For the main kernel image this is not a problem as find_bug() doesn't
depend on the trailing padding bytes when searching for entries:
for (bug = __start___bug_table; bug < __stop___bug_table; ++bug)
if (bugaddr == bug_addr(bug))
return bug;
However for modules, module_bug_finalize() depends on the trailing
bytes when calculating the number of entries:
mod->num_bugs = sechdrs[i].sh_size / sizeof(struct bug_entry);
... and as the last bug_entry lacks the necessary padding bytes, this entry
will not be counted, e.g. in the case of a single entry:
sechdrs[i].sh_size == 6
sizeof(struct bug_entry) == 8;
sechdrs[i].sh_size / sizeof(struct bug_entry) == 0;
Consequently module_find_bug() will miss the last bug_entry when it does:
for (i = 0; i < mod->num_bugs; ++i, ++bug)
if (bugaddr == bug_addr(bug))
goto out;
... which can lead to a kenrel panic due to an unhandled bug.
This can be demonstrated with the following module:
static int __init buginit(void)
{
WARN(1, "hello\n");
return 0;
}
static void __exit bugexit(void)
{
}
module_init(buginit);
module_exit(bugexit);
MODULE_LICENSE("GPL");
... which will trigger a kernel panic when loaded:

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 204f9ed4bad6293933179517624143b8f412347c ]
The USB DP/DM HS PHY interrupts need to be provided by the PDC interrupt
controller in order to be able to wake the system up from low-power
states and to be able to detect disconnect events, which requires
triggering on falling edges.
A recent commit updated the trigger type but failed to change the
interrupt provider as required. This leads to the current Linux driver
failing to probe instead of printing an error during suspend and USB
wakeup not working as intended.

the interrupt type to be consistent between both devices. This ensures
correct setup of the interrupt line regardless of probing order.

commit 3c0696076aad60a2f04c019761921954579e1b0e upstream.
It is currently possible for a userspace application to enter an
infinite page fault loop when using HugeTLB pages implemented with
contiguous PTEs when HAFDBS is not available. This happens because:
1. The kernel may sometimes write PTEs that are sw-dirty but hw-clean
(PTE_DIRTY | PTE_RDONLY | PTE_WRITE).
2. If, during a write, the CPU uses a sw-dirty, hw-clean PTE in handling
the memory access on a system without HAFDBS, we will get a page
fault.
3. HugeTLB will check if it needs to update the dirty bits on the PTE.
For contiguous PTEs, it will check to see if the pgprot bits need
updating. In this case, HugeTLB wants to write a sequence of
sw-dirty, hw-dirty PTEs, but it finds that all the PTEs it is about
to overwrite are all pte_dirty() (pte_sw_dirty() => pte_dirty()),
so it thinks no update is necessary.
We can get the kernel to write a sw-dirty, hw-clean PTE with the
following steps (showing the relevant VMA flags and pgprot bits):
i. Create a valid, writable contiguous PTE.
VMA vmflags: VM_SHARED | VM_READ | VM_WRITE
VMA pgprot bits: PTE_RDONLY | PTE_WRITE
PTE pgprot bits: PTE_DIRTY | PTE_WRITE
ii. mprotect the VMA to PROT_NONE.
VMA vmflags: VM_SHARED
VMA pgprot bits: PTE_RDONLY
PTE pgprot bits: PTE_DIRTY | PTE_RDONLY
iii. mprotect the VMA back to PROT_READ | PROT_WRITE.
VMA vmflags: VM_SHARED | VM_READ | VM_WRITE
VMA pgprot bits: PTE_RDONLY | PTE_WRITE
PTE pgprot bits: PTE_DIRTY | PTE_WRITE | PTE_RDONLY
Make it impossible to create a writeable sw-dirty, hw-clean PTE with
pte_modify(). Such a PTE should be impossible to create, and there may
be places that assume that pte_dirty() implies pte_hw_dirty().

commit c854188ea01062f5a5fd7f05658feb1863774eaa upstream.
We currently expose the PMU version of the host to the guest via
emulation of the DFR0_EL1 and AA64DFR0_EL1 debug feature registers.
However many of the features offered beyond PMUv3 for 8.1 are not
supported in KVM. Examples of this include support for the PMMIR
registers (added in PMUv3 for ARMv8.4) and 64-bit event counters
added in (PMUv3 for ARMv8.5).
Let's trap the Debug Feature Registers in order to limit
PMUVer/PerfMon in the Debug Feature Registers to PMUv3 for ARMv8.1
to avoid unexpected behaviour.
Both ID_AA64DFR0.PMUVer and ID_DFR0.PerfMon follow the "Alternative ID
scheme used for the Performance Monitors Extension version" where 0xF
means an IMPLEMENTATION DEFINED PMU is implemented, and values 0x0-0xE
are treated as with an unsigned field (with 0x0 meaning no PMU is
present). As we don't expect to expose an IMPLEMENTATION DEFINED PMU,
and our cap is below 0xF, we can treat these fields as unsigned when
applying the cap.

commit 8e35aa642ee4dab01b16cc4b2df59d1936f3b3c2 upstream.
When emulating ID registers there is often a need to cap the version
bits of a feature such that the guest will not use features that the
host is not aware of. For example, when KVM mediates access to the PMU
by emulating register accesses.
Let's add a helper that extracts a performance monitors ID field and
caps the version to a given value.
Fields that identify the version of the Performance Monitors Extension
do not follow the standard ID scheme, and instead follow the scheme
described in ARM DDI 0487E.a page D13-2825 "Alternative ID scheme used
for the Performance Monitors Extension version". The value 0xF means an
IMPLEMENTATION DEFINED PMU is present, and values 0x0-OxE can be treated
the same as an unsigned field with 0x0 meaning no PMU is present.

In linux-6.1, the related code is refactored in commit 124c49b1b5d9
("arm64: armv8_deprecated: rework deprected instruction handling") and this
issue was incidentally fixed. I have adapted the patch set to linux stable
5.10. However, 4.19 and 5.10 are too different and the patch set is
hard to adapt to 4.19.
This patch is to solve the problem of repeated addition of linked lists
described below with few changes.
How to reproduce:
CONFIG_ARMV8_DEPRECATED=y, CONFIG_SWP_EMULATION=y, and CONFIG_DEBUG_LIST=y,
then launch two shell executions:
#!/bin/bash
while [ 1 ];
do
echo 1 > /proc/sys/abi/swp
done
or "echo 1 > /proc/sys/abi/swp" and then aunch two shell executions:
#!/bin/bash
while [ 1 ];
do
echo 0 > /proc/sys/abi/swp
done
In emulation_proc_handler(), read and write operations are performed on
insn->current_mode. In the concurrency scenario, mutex only protects
writing insn->current_mode, and not protects the read. Suppose there are
two concurrent tasks, task1 updates insn->current_mode to INSN_EMULATE
in the critical section, the prev_mode of task2 is still the old data
INSN_UNDEF of insn->current_mode. As a result, two tasks call
update_insn_emulation_mode twice with prev_mode = INSN_UNDEF and
current_mode = INSN_EMULATE, then call register_emulation_hooks twice,
resulting in a list_add double problem.
After applying this patch, the following list add or list del double
warnings never occur.
