[ Upstream commit 1010b4c012b0d78dfb9d3132b49aa2ef024a07a7 ]
Multiple race conditions existed between the PCIe hotplug driver and the
EEH driver, leading to a variety of kernel oopses of the same general
nature:
<pcie device unplug>
<eeh driver trigger>
<hotplug removal trigger>
<pcie tree reconfiguration>
<eeh recovery next step>
<oops in EEH driver bus iteration loop>
A second class of oops is also seen when the underlying bus disappears
during device recovery.
Refactor the EEH module to be PCI rescan and remove safe. Also clean
up a few minor formatting / readability issues.

The PowerNV hotplug driver needs to be able to clear any frozen PE(s)
on the PHB after suprise removal of a downstream device.
Export the eeh_unfreeze_pe() symbol to allow implementation of this

[ Upstream commit c32969d0362a790fbc6117e0b6a737a7e510b843 ]
arch/sh/Makefile defines and exports ld-bfd to be used by
arch/sh/boot/compressed/Makefile and arch/sh/boot/romimage/Makefile.
However some shells, including dash, will not pass through environment
variables whose name includes a hyphen. Usually GNU make does not use
a shell to recurse, but if e.g. $(srctree) contains '~' it will use a
shell here.
Other instances of this problem were previously fixed by commits
2bfbe7881ee0 "kbuild: Do not use hyphen in exported variable name"
and 82977af93a0d "sh: rename suffix-y to suffix_y".
Rename the variable to ld_bfd.

[ Upstream commit 7826c8f37220daabf90c09fcd9a835d6763f1372 ]
The Smnpm extension requires special handling because the guest ISA
extension maps to a different extension (Ssnpm) on the host side.
commit 1851e7836212 ("RISC-V: KVM: Allow Smnpm and Ssnpm extensions for
guests") missed that the vcpu->arch.isa bit is based only on the host
extension, so currently both KVM_RISCV_ISA_EXT_{SMNPM,SSNPM} map to
vcpu->arch.isa[RISCV_ISA_EXT_SSNPM]. This does not cause any problems
for the guest, because both extensions are force-enabled anyway when the
host supports Ssnpm, but prevents checking for (guest) Smnpm in the SBI
FWFT logic.
Redefine kvm_isa_ext_arr to look up the guest extension, since only the
guest -> host mapping is unambiguous. Factor out the logic for checking
for host support of an extension, so this special case only needs to be
handled in one place, and be explicit about which variables hold a host
vs a guest ISA extension.

[ Upstream commit b114fcee766d5101eada1aca7bb5fd0a86c89b35 ]
In the ARM64 BPF JIT when prog->aux->exception_boundary is set for a BPF
program, find_used_callee_regs() is not called because for a program
acting as exception boundary, all callee saved registers are saved.
find_used_callee_regs() sets `ctx->fp_used = true;` when it sees FP
being used in any of the instructions.
For programs acting as exception boundary, ctx->fp_used remains false
even if frame pointer is used by the program and therefore, FP is not
set-up for such programs in the prologue. This can cause the kernel to
crash due to a pagefault.
Fix it by setting ctx->fp_used = true for exception boundary programs as
fp is always saved in such programs.

[ Upstream commit cbbcfb94c55c02a8c4ce52b5da0770b5591a314c ]
Mark Rutland noticed that the task parameter is ignored and
'current' is being used instead. Since this is usually
what its passed, it hasn't yet been causing problems but likely
will as the code gets more testing.
But, once this is fixed, it creates a new bug in copy_thread_gcs()
since the gcs_el_mode isn't yet set for the task before its being
checked. Move gcs_alloc_thread_stack() after the new task's
gcs_el0_mode initialization to avoid this.

[ Upstream commit 344b6580472451390d070c65c27f59716a1deecb ]
When CONFIG_DEBUG_EFI is enabled, some objects are needlessly rebuilt.
[Steps to reproduce]
Enable CONFIG_DEBUG_EFI and run 'make' twice in a clean source tree.
On the second run, arch/arm64/kernel/head.o is rebuilt even though
no files have changed.
$ make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- clean
$ make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu-
[ snip ]
$ make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu-
CALL scripts/checksyscalls.sh
AS arch/arm64/kernel/head.o
AR arch/arm64/kernel/built-in.a
AR arch/arm64/built-in.a
AR built-in.a
[ snip ]
The issue is caused by the use of the $(realpath ...) function.
At the time arch/arm64/kernel/Makefile is parsed on the first run,
$(objtree)/vmlinux does not exist. As a result,
$(realpath $(objtree)/vmlinux) expands to an empty string.
On the second run of Make, $(objtree)/vmlinux already exists, so
$(realpath $(objtree)/vmlinux) expands to the absolute path of vmlinux.
However, this change in the command line causes arch/arm64/kernel/head.o
to be rebuilt.
To address this issue, use $(abspath ...) instead, which does not require
the file to exist. While $(abspath ...) does not resolve symlinks, this
should be fine from a debugging perspective.
The GNU Make manual [1] clearly explains the difference between the two:
$(realpath names...)
For each file name in names return the canonical absolute name.
A canonical name does not contain any . or .. components, nor any
repeated path separators (/) or symlinks. In case of a failure the
empty string is returned. Consult the realpath(3) documentation for
a list of possible failure causes.
$(abspath namees...)
For each file name in names return an absolute name that does not
contain any . or .. components, nor any repeated path separators (/).
Note that, in contrast to realpath function, abspath does not resolve
symlinks and does not require the file names to refer to an existing
file or directory. Use the wildcard function to test for existence.
The same problem exists in drivers/firmware/efi/libstub/Makefile.zboot.
On the first run of Make, $(obj)/vmlinuz.efi.elf does not exist when the
Makefile is parsed, so -DZBOOT_EFI_PATH is set to an empty string.
Replace $(realpath ...) with $(abspath ...) there as well.

[ Upstream commit 83f672a7f69ec38b1bbb27221e342937f68c11c7 ]
When MACH_IS_MVME147, the boot console calls mvme147_scc_write() to
generate console output. That will continue to work even after
debug_cons_nputs() becomes unavailable so there's no need to
unregister the boot console.
Take the opportunity to remove a repeated MACH_IS_* test. Use the
actual .write method (instead of a wrapper) and test that pointer
instead. This means adding an unused parameter to debug_cons_nputs() for
consistency with the struct console API.
early_printk.c is only built when CONFIG_EARLY_PRINTK=y. As of late,
head.S is only built when CONFIG_MMU_MOTOROLA=y. So let the former symbol
depend on the latter, to obviate some ifdef conditionals.

[ Upstream commit 41a1452759a8b1121df9cf7310acf31d766ba70b ]
IO hotplug add event is handled in the user space with drmgr tool.
After the device is enabled, the user space uses /sys/kernel/dlpar
interface with “dt add index <drc_index>” to update the device tree.
The kernel interface (dlpar_hp_dt_add()) finds the parent node for
the specified ‘drc_index’ from ibm,drc-info property. The recent FW
provides this property from 2017 onwards. But KVM guest code in
some releases is still using the older SLOF firmware which has
ibm,drc-indexes property instead of ibm,drc-info.
If the ibm,drc-info is not available, this patch adds changes to
search ‘drc_index’ from the indexes array in ibm,drc-indexes
property to support old FW.

[ Upstream commit cd803da7c033e376a66793a43ee98e136bc6cc25 ]
Old revisions of the ROCK 4D board have a dedicated crystal to
supply the RTL8211F PHY's 25MHz clock input. At least some newer
revisions instead use REFCLKO25M_GMAC0_OUT. The DT already has
this half-prepared, but there are some issues:
1. The DT relies on auto-selecting the right PHY driver, which
requires that it works good enough to read the ID registers.
This does not work without the clock, which is handled by
the PHY driver. By updating the compatible to contain the
RTL8211F IDs, so that the operating system can choose the
right PHY driver without relying on a pre-powered PHY.
2. Despite the name REFCLKO25M_GMAC0_OUT could also provide a
different frequency, so ensure it is explicitly set to 25
MHz as expected by the PHY.
3. While at it switch from deprecated "enable-gpio" to standard
"enable-gpios".

[ Upstream commit ab9f2388e0b99cd164ddbd74a6133d3070e2788d ]
After a recent restructuring of the ITS mitigation, RSB stuffing can no longer
be enabled in eIBRS+Retpoline mode. Before ITS, retbleed mitigation only
allowed stuffing when eIBRS was not enabled. This was perfectly fine since
eIBRS mitigates retbleed.
However, RSB stuffing mitigation for ITS is still needed with eIBRS. The
restructuring solely relies on retbleed to deploy stuffing, and does not allow
it when eIBRS is enabled. This behavior is different from what was before the
restructuring. Fix it by allowing stuffing in eIBRS+retpoline mode also.

The retbleed select function leaves the mitigation to AUTO in some cases.
Moreover, the update function can also set the mitigation to AUTO. This
is inconsistent with other mitigations and requires explicit handling of
AUTO at the end of update step.
Make sure a mitigation gets selected in the select step, and do not change
it to AUTO in the update step. When no mitigation can be selected leave it
to NONE, which is what AUTO was getting changed to in the end.

The blsp_dma controller is shared between the different subsystems,
which is why it is already initialized by the firmware. We should not
reinitialize it from Linux to avoid potential other users of the DMA
engine to misbehave.
In mainline this can be described using the "qcom,controlled-remotely"
property. In the downstream/vendor kernel from Qualcomm there is an
opposite "qcom,managed-locally" property. This property is *not* set
for the qcom,sps-dma@7884000 and qcom,sps-dma@7ac4000 [1] so adding
"qcom,controlled-remotely" upstream matches the behavior of the
downstream/vendor kernel.
Adding this fixes booting Longcheer L9360.

Coresight
[ Upstream commit bd4f35786d5f0798cc1f8c187a81a7c998e6c58f ]
An infinite loop has been created by the Coresight devices. When only a
source device is enabled, the coresight_find_activated_sysfs_sink function
is recursively invoked in an attempt to locate an active sink device,
ultimately leading to a stack overflow and system crash. Therefore, disable
the replicator1 to break the infinite loop and prevent a potential stack
overflow.
