commit fad58a41b84667cb6c9232371fc3af77d4443889 upstream.
For Gen-1 targets like SDM630, it is seen that stressing out the
controller in host mode results in HC died error:
xhci-hcd.12.auto: xHCI host not responding to stop endpoint command
xhci-hcd.12.auto: xHCI host controller not responding, assume dead
xhci-hcd.12.auto: HC died; cleaning up
And at this instant only restarting the host mode fixes it. Disable
SuperSpeed instance in park mode for SDM630 to mitigate this issue.

commit d201c92bff90f3d3d0b079fc955378c15c0483cc upstream.
Correct the specified regulator-min-microvolt value for the buck DCDC_REG2
regulator, which is part of the Rockchip RK809 PMIC, in the Pine64 Quartz64
Model B board dts. According to the RK809 datasheet, version 1.01, this
regulator is capable of producing voltages as low as 0.5 V on its output,
instead of going down to 0.9 V only, which is additionally confirmed by the
regulator-min-microvolt values found in the board dts files for the other
supported boards that use the same RK809 PMIC.
This allows the DVFS to clock the GPU on the Quartz64 Model B below 700 MHz,
all the way down to 200 MHz, which saves some power and reduces the amount of
generated heat a bit, improving the thermal headroom and possibly improving
the bursty CPU and GPU performance on this board.
This also eliminates the following warnings in the kernel log:
core: _opp_supported_by_regulators: OPP minuV: 825000 maxuV: 825000, not supported by regulator
panfrost fde60000.gpu: _opp_add: OPP not supported by regulators (200000000)

commit d3882564a77c21eb746ba5364f3fa89b88de3d61 upstream.
Using sys_io_pgetevents() as the entry point for compat mode tasks
works almost correctly, but misses the sign extension for the min_nr
and nr arguments.
This was addressed on parisc by switching to
compat_sys_io_pgetevents_time64() in commit 6431e92fc827 ("parisc:
io_pgetevents_time64() needs compat syscall in 32-bit compat mode"),
as well as by using more sophisticated system call wrappers on x86 and
s390. However, arm64, mips, powerpc, sparc and riscv still have the
same bug.
Change all of them over to use compat_sys_io_pgetevents_time64()
like parisc already does. This was clearly the intention when the
function was originally added, but it got hooked up incorrectly in
the tables.

[ Upstream commit 6db1208bf95b4c091897b597c415e11edeab2e2d ]
An unintended consequence of commit 9c573cd31343 ("randomize_kstack:
Improve entropy diffusion") was that the per-architecture entropy size
filtering reduced how many bits were being added to the mix, rather than
how many bits were being used during the offsetting. All architectures
fell back to the existing default of 0x3FF (10 bits), which will consume
at most 1KiB of stack space. It seems that this is working just fine,
so let's avoid the confusion and update everything to use the default.
The prior intent of the per-architecture limits were:
arm64: capped at 0x1FF (9 bits), 5 bits effective
powerpc: uncapped (10 bits), 6 or 7 bits effective
riscv: uncapped (10 bits), 6 bits effective
x86: capped at 0xFF (8 bits), 5 (x86_64) or 6 (ia32) bits effective
s390: capped at 0xFF (8 bits), undocumented effective entropy
Current discussion has led to just dropping the original per-architecture
filters. The additional entropy appears to be safe for arm64, x86,
and s390. Quoting Arnd, "There is no point pretending that 15.75KB is
somehow safe to use while 15.00KB is not."

[ Upstream commit 819fe8c96a5172dfd960e5945e8f00f8fed32953 ]
There are two issues with SDHC2 configuration for SA8155P-ADP,
which prevent use of SDHC2 and causes issues with ethernet:
- Card Detect pin for SHDC2 on SA8155P-ADP is connected to gpio4 of
PMM8155AU_1, not to SoC itself. SoC's gpio4 is used for DWMAC
TX. If sdhc driver probes after dwmac driver, it reconfigures
gpio4 and this breaks Ethernet MAC.
- pinctrl configuration mentions gpio96 as CD pin. It seems it was
copied from some SM8150 example, because as mentioned above,
correct CD pin is gpio4 on PMM8155AU_1.
This patch fixes both mentioned issues by providing correct pin handle
and pinctrl configuration.

commit c92e8b9eacebb4060634ebd9395bba1b29aadc68 upstream.
We recently upgraded the view of ESR_EL2 to 64bit, in keeping with
the requirements of the architecture.
However, the AArch32 emulation code was left unaudited, and the
(already dodgy) code that triages whether a trap is spurious or not
(because the condition code failed) broke in a subtle way:
If ESR_EL2.ISS2 is ever non-zero (unlikely, but hey, this is the ARM
architecture we're talking about), the hack that tests the top bits
of ESR_EL2.EC will break in an interesting way.
Instead, use kvm_vcpu_trap_get_class() to obtain the EC, and list
all the possible ECs that can fail a condition code check.
While we're at it, add SMC32 to the list, as it is explicitly listed
as being allowed to trap despite failing a condition code check (as
described in the HCR_EL2.TSC documentation).

commit 947051e361d551e0590777080ffc4926190f62f2 upstream.
When userspace writes to one of the core registers, we make
sure to narrow the corresponding GPRs if PSTATE indicates
an AArch32 context.
The code tries to check whether the context is EL0 or EL1 so
that it narrows the correct registers. But it does so by checking
the full PSTATE instead of PSTATE.M.
As a consequence, and if we are restoring an AArch32 EL0 context
in a 64bit guest, and that PSTATE has *any* bit set outside of
PSTATE.M, we narrow *all* registers instead of only the first 15,
destroying the 64bit state.
Obviously, this is not something the guest is likely to enjoy.
Correctly masking PSTATE to only evaluate PSTATE.M fixes it.

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:
tegra132-norrin.dts:12.3-36: Warning (alias_paths): /aliases:rtc0: aliases property is not a valid node (/i2c@7000d000/as3722@40)

[ 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:

commit 657eef0a5420a02c02945ed8c87f2ddcbd255772 upstream.
Currently CONFIG_ARM64_USE_LSE_ATOMICS depends upon CONFIG_JUMP_LABEL,
as the inline atomics were indirected with a static branch.
However, since commit:
21fb26bfb01ffe0d ("arm64: alternatives: add alternative_has_feature_*()")
... we use an alternative_branch (which is always available) rather than
a static branch, and hence the dependency is unnecessary.
Remove the stale dependency, along with the stale include. This will
allow the use of LSE atomics in kernels built with CONFIG_JUMP_LABEL=n,
and reduces the risk of circular header dependencies via <asm/lse.h>.

When parsing a GICv2 attribute that contains a cpuid, handle this
as the vcpu_id, not a vcpu_idx, as userspace cannot really know
the mapping between the two. For this, use kvm_get_vcpu_by_id()
instead of kvm_get_vcpu().
Take this opportunity to get rid of the pointless check against
online_vcpus, which doesn't make much sense either, and switch
to FIELD_GET as a way to extract the vcpu_id.

[ Upstream commit 43853e843aa6c3d47ff2b0cce898318839483d05 ]
Remove a redundant node from the Pine64 Pinebook Pro dts, which is intended
to provide a value for the delay in PCI Express enumeration, but that isn't
supported without additional out-of-tree kernel patches.
There were already efforts to upstream those kernel patches, because they
reportedly make some PCI Express cards (such as LSI SAS HBAs) usable in
Pine64 RockPro64 (which is also based on the RK3399); otherwise, those PCI
Express cards fail to enumerate. However, providing the required background
and explanations proved to be a tough nut to crack, which is the reason why
those patches remain outside of the kernel mainline for now.
If those out-of-tree patches eventually become upstreamed, the resulting
device-tree changes will almost surely belong to the RK3399 SoC dtsi. Also,
the above-mentioned unusable-without-out-of-tree-patches PCI Express devices
are in all fairness not usable in a Pinebook Pro without some extensive
hardware modifications, which is another reason to delete this redundant
node. When it comes to the Pinebook Pro, only M.2 NVMe SSDs can be installed
out of the box (using an additional passive adapter PCB sold separately by
Pine64), which reportedly works fine with no additional patches.

[ 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 a2ac2a1b02590a22a236c43c455f421cdede45f5 ]
The MT7531 switch listens on PHY address 0x1f on an MDIO bus. I've got two
findings that support this. There's no bootstrapping option to change the
PHY address of the switch. The Linux driver hardcodes 0x1f as the PHY
address of the switch. So the reg property on the device tree is currently
ignored by the Linux driver.
Therefore, describe the correct PHY address on Banana Pi BPI-R2 Pro that
has this switch.

The reason is swsusp_save() -> copy_data_pages() -> page_is_saveable()
-> kernel_page_present() assuming that a page is always present when
can_set_direct_map() is false (all of rodata_full,
debug_pagealloc_enabled() and arm64_kfence_can_set_direct_map() false),
irrespective of the MEMBLOCK_NOMAP ranges. Such MEMBLOCK_NOMAP regions
should not be saved during hibernation.
This problem was introduced by changes to the pfn_valid() logic in
commit a7d9f306ba70 ("arm64: drop pfn_valid_within() and simplify
pfn_valid()").
Similar to other architectures, drop the !can_set_direct_map() check in
kernel_page_present() so that page_is_savable() skips such pages.

The actual clock show wrong frequency:

cat /sys/kernel/debug/mmc0/ios
clock: 200000000 Hz
actual clock: 166000000 Hz
^^^^^^^^^
.....
According to
sdhc0_lpcg: clock-controller@5b200000 {
compatible = "fsl,imx8qxp-lpcg";
reg = <0x5b200000 0x10000>;

clocks = <&clk IMX_SC_R_SDHC_0 IMX_SC_PM_CLK_PER>,
<&conn_ipg_clk>, <&conn_axi_clk>;
clock-indices = <IMX_LPCG_CLK_0>, <IMX_LPCG_CLK_4>,

"sdhc0_lpcg_ipg_clk",
"sdhc0_lpcg_ahb_clk";
power-domains = <&pd IMX_SC_R_SDHC_0>;
}
"per_clk" should be IMX_LPCG_CLK_0 instead of IMX_LPCG_CLK_5.
After correct clocks order:
echo on >/sys/devices/platform/bus\@5b000000/5b010000.mmc/power/control
cat /sys/kernel/debug/mmc0/ios
clock: 200000000 Hz
