commit 914d6f44fc50 ("RISC-V: only iterate over possible CPUs in ISA
string parser") changed riscv_fill_hwcap() from iterating over CPU DT
nodes to iterating over logical CPU IDs. Since this function runs long
before cpu_dev_init() creates CPU devices, it hits the fallback path in
of_cpu_device_node_get(), which itself iterates over the DT nodes,
searching for a node with the requested CPU ID. (Incidentally, this
makes riscv_fill_hwcap() now take quadratic time.)
riscv_fill_hwcap() passes a logical CPU ID to of_cpu_device_node_get(),
which uses the arch_match_cpu_phys_id() hook to translate the logical ID
to a physical ID as found in the DT.
arch_match_cpu_phys_id() has a generic weak definition, and RISC-V
provides a strong definition using cpuid_to_hartid_map(). However, the
RISC-V specific implementation is located in arch/riscv/kernel/smp.c,
and that file is only compiled when SMP is enabled.
As a result, when SMP is disabled, the generic definition is used, and
riscv_isa gets initialized based on the ISA string of hart 0, not the
boot hart. On FU740, this means has_fpu() returns false, and userspace
crashes when trying to use floating-point instructions.
Fix this by moving arch_match_cpu_phys_id() to a file which is always
compiled.

Fixes: 914d6f44fc50 ("RISC-V: only iterate over possible CPUs in ISA string parser")

The commit d73ef2d69c0d ("rtnetlink: let rtnl_bridge_setlink checks
IFLA_BRIDGE_MODE length") added the nla_len check in rtnl_bridge_setlink,
which is the only caller for ndo_bridge_setlink handlers defined in
low-level driver codes. Hence, this patch cleanups the redundant checks in
each ndo_bridge_setlink handler function.

Fix the following warning:
drivers/net/ethernet/broadcom/bnxt/bnxt_dcb.c: In function ‘bnxt_hwrm_queue_cos2bw_cfg’:

Fix it by modifying struct hwrm_queue_cos2bw_cfg_input to use an array
of sub struct similar to the previous patch. This will eliminate the
pointer arithmetc to calculate the destination pointer passed to
memcpy().

^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Modify the FW interface defintion of struct hwrm_queue_cos2bw_qcfg_output
to use an array of sub struct for the queue1 to queue7 fields. Note that
the layout of the queue0 fields are different and these are not part of
the array. This makes the code much cleaner by removing the pointer

40613da52b13 ("PCI: acpiphp: Reassign resources on bridge if necessary")
changed acpiphp hotplug to use pci_assign_unassigned_bridge_resources()
which depends on bridge being available, however enable_slot() can be
called without bridge associated:
1. Legitimate case of hotplug on root bus (widely used in virt world)
2. A (misbehaving) firmware, that sends ACPI Bus Check notifications to
non existing root ports (Dell Inspiron 7352/0W6WV0), which end up at
enable_slot(..., bridge = 0) where bus has no bridge assigned to it.
acpihp doesn't know that it's a bridge, and bus specific 'PCI
subsystem' can't augment ACPI context with bridge information since
the PCI device to get this data from is/was not available.
Issue is easy to reproduce with QEMU's 'pc' machine, which supports PCI
hotplug on hostbridge slots. To reproduce, boot kernel at commit
40613da52b13 in VM started with following CLI (assuming guest root fs is
installed on sda1 partition):
# qemu-system-x86_64 -M pc -m 1G -enable-kvm -cpu host \
-monitor stdio -serial file:serial.log \
-kernel arch/x86/boot/bzImage \
-append "root=/dev/sda1 console=ttyS0" \
guest_disk.img
Once guest OS is fully booted at qemu prompt:
(qemu) device_add e1000
(check serial.log) it will cause NULL pointer dereference at:
void pci_assign_unassigned_bridge_resources(struct pci_dev *bridge)
{
struct pci_bus *parent = bridge->subordinate;
BUG: kernel NULL pointer dereference, address: 0000000000000018
? pci_assign_unassigned_bridge_resources+0x1f/0x260
enable_slot+0x21f/0x3e0
acpiphp_hotplug_notify+0x13d/0x260
acpi_device_hotplug+0xbc/0x540
acpi_hotplug_work_fn+0x15/0x20
process_one_work+0x1f7/0x370
worker_thread+0x45/0x3b0
The issue was discovered on Dell Inspiron 7352/0W6WV0 laptop with following
sequence:
1. Suspend to RAM
2. Wake up with the same backtrace being observed:
3. 2nd suspend to RAM attempt makes laptop freeze
Fix it by using __pci_bus_assign_resources() instead of
pci_assign_unassigned_bridge_resources() as we used to do, but only in case
when bus doesn't have a bridge associated (to cover for the case of ACPI
event on hostbridge or non existing root port).
That lets us keep hotplug on root bus working like it used to and at the
same time keeps resource reassignment usable on root ports (and other 1st
level bridges) that was fixed by 40613da52b13.

The changes from commit 32832a407a71 ("io_uring: Fix io_uring mmap() by
using architecture-provided get_unmapped_area()") to the parisc
implementation of get_unmapped_area() broke glibc's locale-gen
executable when running on parisc.
This patch reverts those architecture-specific changes, and instead
adjusts in io_uring_mmu_get_unmapped_area() the pgoff offset which is
then given to parisc's get_unmapped_area() function. This is much
cleaner than the previous approach, and we still will get a coherent
addresss.
This patch has no effect on other architectures (SHM_COLOUR is only
defined on parisc), and the liburing testcase stil passes on parisc.

Buffers mapped with pgprot_writecombined() are not correctly
flushed. This triggers issues on VPU access using random
memory content such as MMU translation faults, invalid context
descriptors being fetched and can lead to VPU FW crashes.

A switch from OSI to PC mode is only possible if all CPUs other than the
calling one are OFF, either through a call to CPU_OFF or not yet booted.
Currently OSI mode is enabled before power domains are created. In cases
where CPUidle states are not using hierarchical CPU topology the bail out
path tries to switch back to PC mode which gets denied by firmware since
other CPUs are online at this point and creates inconsistent state as
firmware is in OSI mode and Linux in PC mode.
This change moves enabling OSI mode after power domains are created,
this would makes sure that hierarchical CPU topology is used before
switching firmware to OSI mode.

This reverts commit 46d21ec067490ab9cdcc89b9de5aae28786a8b8e.
The tests were made with a specific workload, further tests on a
recently updated fedora 38 system with a system wide perf.data file
shows 'perf report' taking excessive time resolving inlines in vmlinux,
so lets revert this until a full investigation and improvement on the
addr2line support code is made.

Compared to all the other work we're already doing to deliver
an skb to userspace this is very cheap - at worse an extra
call to ktime_get_real() - and very useful.
(and indeed it may even be cheaper if we're running from other hooks)
(background: Android occasionally logs packets which
caused wake from sleep/suspend and we'd like to have
timestamps reliably associated with these events)

RX full flags are raised if certain types of RX FIFO are full, and then
drop all following MPDU of AMPDU. In order to resume to receive MPDU
when RX FIFO becomes available, we clear the register bits by the
commit a0d99ebb3ecd ("wifi: rtw89: initialize DMA of CMAC"). But, 8852AE
needs more settings to support this. To quickly fix disconnection problem,
revert the behavior as before.
