iwlwifi: pcie: move power gating workaround earlier in the flow
commit 0df36b90c47d93295b7e393da2d961b2f3b6cde4 upstream.
We need to reset the NIC after setting the bits to enable power
gating and that cannot be done too late in the flow otherwise it
cleans other registers and things that were already configured,
causing initialization to fail.
In order to fix this, move the function to the common code in trans.c
so it can be called directly from there at an earlier point, just
after the reset we already do during initialization.

ocxl: Fix concurrent AFU open and device removal
commit a58d37bce0d21cf7fbd589384c619e465ef2f927 upstream.
If an ocxl device is unbound through sysfs at the same time its AFU is
being opened by a user process, the open code may dereference freed
stuctures, which can lead to kernel oops messages. You'd have to hit a
tiny time window, but it's possible. It's fairly easy to test by
making the time window bigger artificially.
Fix it with a combination of 2 changes:
- when an AFU device is found in the IDR by looking for the device
minor number, we should hold a reference on the device until after
the context is allocated. A reference on the AFU structure is kept
when the context is allocated, so we can release the reference on
the device after the context allocation.
- with the fix above, there's still another even tinier window,
between the time the AFU device is found in the IDR and the
reference on the device is taken. We can fix this one by removing
the IDR entry earlier, when the device setup is removed, instead
of waiting for the 'release' device callback. With proper locking
around the IDR.

x86/MCE/AMD: Allow Reserved types to be overwritten in smca_banks[]
commit 966af20929ac24360ba3fac5533eb2ab003747da upstream.
Each logical CPU in Scalable MCA systems controls a unique set of MCA
banks in the system. These banks are not shared between CPUs. The bank
types and ordering will be the same across CPUs on currently available
systems.
However, some CPUs may see a bank as Reserved/Read-as-Zero (RAZ) while
other CPUs do not. In this case, the bank seen as Reserved on one CPU is
assumed to be the same type as the bank seen as a known type on another
CPU.
In general, this occurs when the hardware represented by the MCA bank
is disabled, e.g. disabled memory controllers on certain models, etc.
The MCA bank is disabled in the hardware, so there is no possibility of
getting an MCA/MCE from it even if it is assumed to have a known type.
For example:
Full system:
Bank | Type seen on CPU0 | Type seen on CPU1
------------------------------------------------
0 | LS | LS
1 | UMC | UMC
2 | CS | CS
System with hardware disabled:
Bank | Type seen on CPU0 | Type seen on CPU1
------------------------------------------------
0 | LS | LS
1 | UMC | RAZ
2 | CS | CS
For this reason, there is a single, global struct smca_banks[] that is
initialized at boot time. This array is initialized on each CPU as it
comes online. However, the array will not be updated if an entry already
exists.
This works as expected when the first CPU (usually CPU0) has all
possible MCA banks enabled. But if the first CPU has a subset, then it
will save a "Reserved" type in smca_banks[]. Successive CPUs will then
not be able to update smca_banks[] even if they encounter a known bank
type.
This may result in unexpected behavior. Depending on the system
configuration, a user may observe issues enumerating the MCA
thresholding sysfs interface. The issues may be as trivial as sysfs
entries not being available, or as severe as system hangs.
For example:
Bank | Type seen on CPU0 | Type seen on CPU1
------------------------------------------------
0 | LS | LS
1 | RAZ | UMC
2 | CS | CS
Extend the smca_banks[] entry check to return if the entry is a
non-reserved type. Otherwise, continue so that CPUs that encounter a
known bank type can update smca_banks[].

KVM: arm/arm64: Properly handle faulting of device mappings
commit 6d674e28f642e3ff676fbae2d8d1b872814d32b6 upstream. A device mapping is normally always mapped at Stage-2, since there is very little gain in having it faulted in. Nonetheless, it is possible to end-up in a situation where the device mapping has been removed from Stage-2 (userspace munmaped the VFIO region, and the MMU notifier did its job), but present in a userspace mapping (userpace has mapped it back at the same address). In such a situation, the device mapping will be demand-paged as the guest performs memory accesses. This requires to be careful when dealing with mapping size, cache management, and to handle potential execution of a device mapping.

KVM: PPC: Book3S HV: Fix regression on big endian hosts
commit 228b607d8ea1b7d4561945058d5692709099d432 upstream.
VCPU_CR is the offset of arch.regs.ccr in kvm_vcpu.
arch/powerpc/include/asm/kvm_host.h defines arch.regs as a struct
pt_regs, and arch/powerpc/include/asm/ptrace.h defines the ccr field
of pt_regs as "unsigned long ccr". Since unsigned long is 64 bits, a
64-bit load needs to be used to load it, unless an endianness specific
correction offset is added to access the desired subpart. In this
case there is no reason to _not_ use a 64 bit load though.

iocost: over-budget forced IOs should schedule async delay
commit d7bd15a138aef3be227818aad9c501e43c89c8c5 upstream.
When over-budget IOs are force-issued through root cgroup,
iocg_kick_delay() adjusts the async delay accordingly but doesn't
actually schedule async throttle for the issuing task. This bug is
pretty well masked because sooner or later the offending threads are
gonna get directly throttled on regular IOs or have async delay
scheduled by mem_cgroup_throttle_swaprate().
However, it can affect control quality on filesystem metadata heavy
operations. Let's fix it by invoking blkcg_schedule_throttle() when
iocg_kick_delay() says async delay is needed.

commit ab42b48f32d4c766420c3499ee9c0289b7028182 upstream. The "auto-attach" handler function `gsc_hpdi_auto_attach()` calls `dma_alloc_coherent()` in a loop to allocate some DMA data buffers, and also calls it to allocate a buffer for a DMA descriptor chain. However, it does not check the return value of any of these calls. Change `gsc_hpdi_auto_attach()` to return `-ENOMEM` if any of these `dma_alloc_coherent()` calls fail. This will result in the comedi core calling the "detach" handler `gsc_hpdi_detach()` as part of the clean-up, which will call `gsc_hpdi_free_dma()` to free any allocated DMA coherent memory buffers.

USB: EHCI: Do not return -EPIPE when hub is disconnected
commit 64cc3f12d1c7dd054a215bc1ff9cc2abcfe35832 upstream. When disconnecting a USB hub that has some child device(s) connected to it (such as a USB mouse), then the stack tries to clear halt and reset device(s) which are _already_ physically disconnected. The issue has been reproduced with: CPU: IMX6D5EYM10AD or MCIMX6D5EYM10AE. SW: U-Boot 2019.07 and kernel 4.19.40. CPU: HP Proliant Microserver Gen8. SW: Linux version 4.2.3-300.fc23.x86_64 In this situation there will be error bit for MMF active yet the CERR equals EHCI_TUNE_CERR + halt. Existing implementation interprets this as a stall [1] (chapter 8.4.5). The possible conditions when the MMF will be active + halt can be found from [2] (Table 4-13). Fix for the issue is to check whether MMF is active and PID Code is IN before checking for the stall. If these conditions are true then it is not a stall. What happens after the fix is that when disconnecting a hub with attached device(s) the situation is not interpret as a stall.

cpufreq: Avoid leaving stale IRQ work items during CPU offline
commit 85572c2c4a45a541e880e087b5b17a48198b2416 upstream.
The scheduler code calling cpufreq_update_util() may run during CPU
offline on the target CPU after the IRQ work lists have been flushed
for it, so the target CPU should be prevented from running code that
may queue up an IRQ work item on it at that point.
Unfortunately, that may not be the case if dvfs_possible_from_any_cpu
is set for at least one cpufreq policy in the system, because that
allows the CPU going offline to run the utilization update callback
of the cpufreq governor on behalf of another (online) CPU in some
cases.
If that happens, the cpufreq governor callback may queue up an IRQ
work on the CPU running it, which is going offline, and the IRQ work
may not be flushed after that point. Moreover, that IRQ work cannot
be flushed until the "offlining" CPU goes back online, so if any
other CPU calls irq_work_sync() to wait for the completion of that
IRQ work, it will have to wait until the "offlining" CPU is back
online and that may not happen forever. In particular, a system-wide
deadlock may occur during CPU online as a result of that.
The failing scenario is as follows. CPU0 is the boot CPU, so it
creates a cpufreq policy and becomes the "leader" of it
(policy->cpu). It cannot go offline, because it is the boot CPU.
Next, other CPUs join the cpufreq policy as they go online and they
leave it when they go offline. The last CPU to go offline, say CPU3,
may queue up an IRQ work while running the governor callback on
behalf of CPU0 after leaving the cpufreq policy because of the
dvfs_possible_from_any_cpu effect described above. Then, CPU0 is
the only online CPU in the system and the stale IRQ work is still
queued on CPU3. When, say, CPU1 goes back online, it will run
irq_work_sync() to wait for that IRQ work to complete and so it
will wait for CPU3 to go back online (which may never happen even
in principle), but (worse yet) CPU0 is waiting for CPU1 at that
point too and a system-wide deadlock occurs.
To address this problem notice that CPUs which cannot run cpufreq
utilization update code for themselves (for example, because they
have left the cpufreq policies that they belonged to), should also
be prevented from running that code on behalf of the other CPUs that
belong to a cpufreq policy with dvfs_possible_from_any_cpu set and so
in that case the cpufreq_update_util_data pointer of the CPU running
the code must not be NULL as well as for the CPU which is the target
of the cpufreq utilization update in progress.
Accordingly, change cpufreq_this_cpu_can_update() into a regular
function in kernel/sched/cpufreq.c (instead of a static inline in a
header file) and make it check the cpufreq_update_util_data pointer
of the local CPU if dvfs_possible_from_any_cpu is set for the target
cpufreq policy.
Also update the schedutil governor to do the
cpufreq_this_cpu_can_update() check in the non-fast-switch
case too to avoid the stale IRQ work issues.

efi/memreserve: Register reservations as 'reserved' in /proc/iomem
commit ab0eb16205b43ece4c78e2259e681ff3d645ea66 upstream. Memory regions that are reserved using efi_mem_reserve_persistent() are recorded in a special EFI config table which survives kexec, allowing the incoming kernel to honour them as well. However, such reservations are not visible in /proc/iomem, and so the kexec tools that load the incoming kernel and its initrd into memory may overwrite these reserved regions before the incoming kernel has a chance to reserve them from further use. Address this problem by adding these reservations to /proc/iomem as they are created. Note that reservations that are inherited from a previous kernel are memblock_reserve()'d early on, so they are already visible in /proc/iomem.

spi: fsl: use platform_get_irq() instead of of_irq_to_resource()
commit 63aa6a692595d47a0785297b481072086b9272d2 upstream.
Unlike irq_of_parse_and_map() which has a dummy definition on SPARC,
of_irq_to_resource() hasn't.
But as platform_get_irq() can be used instead and is generic, use it.

The problem comes from the error path which calls
irq_dispose_mapping() while the IRQ has been requested with
devm_request_irq().
IRQ doesn't need to be mapped with irq_of_parse_and_map(). The only
need is to get the IRQ virtual number. For that, use
of_irq_to_resource() instead of the
irq_of_parse_and_map()/irq_dispose_mapping() pair.
