In amdgpu_ras_reset_gpu, because bad pages may not be freed,
it has high probability to reserve bad pages failed.
Change to reserve bad pages when freeing VRAM.
v2:
1. avoid allocating the drm_mm node outside of amdgpu_vram_mgr.c
2. move bad page reserving into amdgpu_ras_add_bad_pages, if vram mgr
reserve bad page failed, it will put it into pending list, otherwise
put it into processed list;
3. remove amdgpu_ras_release_bad_pages, because retired page's info has
been moved into amdgpu_vram_mgr
v3:
1. formate code style;
2. rename amdgpu_vram_reserve_scope as amdgpu_vram_reservation;
3. rename scope_pending as reservations_pending;
4. rename scope_processed as reserved_pages;
5. change to iterate over all the pending ones and try to insert them
with drm_mm_reserve_node();
v4:
1. rename amdgpu_vram_mgr_reserve_scope as
amdgpu_vram_mgr_reserve_range;
2. remove unused include "amdgpu_ras.h";
3. rename amdgpu_vram_mgr_check_and_reserve as
amdgpu_vram_mgr_do_reserve;
4. refine amdgpu_vram_mgr_reserve_range to call
amdgpu_vram_mgr_do_reserve.

One issue exposed after below commit with which the system will freeze
at suspend after vGPU is created (no need to activate the vGPU).
commit e6ba76480299 ("drm/i915: Remove i915->kernel_context")
Old implementation pin the intel_context at setup_submission and
unpin it at clean_submission. So after some vGPU is created, the
intel_context is always pinned there although no workload using it.
It will then block i915 enter suspend state.
There is no need to pin it all the time. Pin/unpin it around workload
lifecycle is more reasonable. After GVT enabled suspend/resume, the
pinned intel_context will also get unpined when userspace put VM process
into suspend state since all workloads are retired, then it's safe to
unpin all intel_context for workloads created. So move the pin/unpin to
create_workload and destroy_workload, while still keep the
create/destroy in old place.
V2:
Rebase.

When the system goes to suspend, if the controller is at device mode with
cable connecting to host, the call stack is: cdns3_suspend->
cdns3_gadget_suspend -> cdns3_disconnect_gadget, after cdns3_disconnect_gadget
is called, it owns lock wrongly, it causes the system being deadlock after
resume due to at cdns3_device_thread_irq_handler, it tries to get the lock,
but can't get it forever.
To fix it, we delete the unlock-lock operations at cdns3_disconnect_gadget,
and do it at the caller.

Patch fixes issue caused setting On-chip memory overflow bit in usb_sts
register. The issue occurred because EP_CFG register was set twice
before USB_STS.CFGSTS was set. Every write operation on EP_CFG.BUFFERING
causes that controller increases internal counter holding the number
of reserved on-chip buffers. First time this register was updated in
function cdns3_ep_config before delegating SET_CONFIGURATION request
to class driver and again it was updated when class wanted to enable
endpoint. This patch fixes this issue by configuring endpoints
enabled by class driver in cdns3_gadget_ep_enable and others just
before status stage.

While I thought I had this correct (since it actually did reject modes
like I expected during testing), Ville Syrjala from Intel pointed out
that the logic here isn't correct. max_clock refers to the max data rate
supported by the DP encoder. So, limiting it to the output of ds_clock (which
refers to the maximum dotclock of the downstream DP device) doesn't make any
sense. Additionally, since we're using the connector's bpc as the canonical BPC
we should use this in mode_valid until we support dynamically setting the bpp
based on bandwidth constraints.
https://lists.freedesktop.org/archives/dri-devel/2020-September/280276.html
For more info.
So, let's rewrite this using Ville's advice.
v2:
* Ville pointed out I mixed up the dotclock and the link rate. So fix that...
* ...and also rename all the variables in this function to be more appropriately
labeled so I stop mixing them up.
* Reuse the bpp from the connector for now until we have dynamic bpp selection.
* Use use DIV_ROUND_UP for calculating the mode rate like i915 does, which we
should also have been doing from the start

Ville also pointed out that I got a lot of the logic here wrong as well, whoops.
While I don't think anyone's likely using 3D output with nouveau, the next patch
will make nouveau_conn_mode_valid() make a lot less sense. So, let's just get
rid of it and open-code it like before, while taking care to move the 3D frame
packing calculations on the dot clock into the right place.

Not entirely sure why this never came up when I originally tested this
(maybe some BIOSes already have this setup?) but the ->caps_init vfunc
appears to cause the display engine to throw an exception on driver
init, at least on my ThinkPad P72:
nouveau 0000:01:00.0: disp: chid 0 mthd 008c data 00000000 0000508c 0000102b
This is magic nvidia speak for "You need to have the DMA notifier offset
programmed before you can call NV507D_GET_CAPABILITIES." So, let's fix
this by doing that, and also perform an update afterwards to prevent
racing with the GPU when reading capabilities.
v2:
* Don't just program the DMA notifier offset, make sure to actually
perform an update
v3:
* Don't call UPDATE()
* Actually read the correct notifier fields, as apparently the
CAPABILITIES_DONE field lives in a different location than the main
NV_DISP_CORE_NOTIFIER_1 field. As well, 907d+ use a different
CAPABILITIES_DONE field then pre-907d cards.
v4:
* Don't forget to check the return value of core507d_read_caps()
v5:
* Get rid of NV50_DISP_CAPS_NTFY[14], use NV50_DISP_CORE_NTFY
* Disable notifier after calling GetCapabilities()

We have a few displays in CI that always report their EDID as a bunch of
zeroes. This is consistent behaviour, so one assumes intentional
indication of an "absent" EDID. Flagging these consistent warnings
detracts from CI.
One option would be to ignore the zero EDIDs as intentional behaviour,
but Ville would like to keep the information available for debugging.
The simple alternative then is to reduce the loglevel for all the EDID
dumping from WARN to DEBUG so the information is present but not annoy
CI. Note that the bad EDID dumping is already only shown if
drm.debug=KMS, it's just the loglevel chosen was set to be caught by CI
if it ever occurred as it was expected to be an internal error not
external.

Before this patch, gfs2_fitrim was not properly checking for a "live" file
system. If the file system had something to trim and the file system
was read-only (or spectator) it would start the trim, but when it starts
the transaction, gfs2_trans_begin returns -EROFS (read-only file system)
and it errors out. However, if the file system was already trimmed so
there's no work to do, it never called gfs2_trans_begin. That code is
bypassed so it never returns the error. Instead, it returns a good
return code with 0 work. All this makes for inconsistent behavior:
The same fstrim command can return -EROFS in one case and 0 in another.
This tripped up xfstests generic/537 which reports the error as:
+fstrim with unrecovered metadata just ate your filesystem
This patch adds a check for a "live" (iow, active journal, iow, RW)
file system, and if not, returns the error properly.

Before commit 97fd734ba17e, the local statfs_changeX inode was never
initialized for spectator mounts. However, it still checks for
spectator mounts when unmounting everything. There's no good reason to
lookup the statfs_changeX files because spectators cannot perform recovery.
It still, however, needs the master statfs file for statfs calls.
This patch adds the check for spectator mounts to init_statfs.

Before this patch, function gfs2_meta_sync called filemap_fdatawrite to write
the address space for the metadata being synced. That's great for inodes, but
resource groups all point to the same superblock-address space, sdp->sd_aspace.
Each rgrp has its own range of blocks on which it should operate. That meant
every time an rgrp's metadata was synced, it would write all of them instead
of just the range.
This patch eliminates function gfs2_meta_sync and tailors specific metasync
functions for inodes and rgrps.

Hi,
Before this patch, function init_journal's "undo" directive jumped to label
fail_jinode_gh. But now that it does statfs initialization, it needs to
jump to fail_statfs instead. Failure to do so means that mount failures
after init_journal is successful will neglect to let go of the proper
statfs information, stranding the statfs_changeX inodes. This makes it
impossible to free its glocks, and results in:
gfs2: fsid=sda.s: G: s:EX n:2/805f f:Dqob t:EX d:UN/603701000 a:0 v:0 r:4 m:200 p:1

VFS: Busy inodes after unmount of sda. Self-destruct in 5 seconds. Have a nice day...
The next time the file system is mounted, it then reuses the same glocks,
which ends in a kernel NULL pointer dereference when trying to dump the
reused glock.
This patch makes the "undo" function of init_journal jump to fail_statfs
so the statfs files are properly deconstructed upon failure.

Gfs2 creates an address space for its rgrps called sd_aspace, but it never
called truncate_inode_pages_final on it. This confused vfs greatly which
tried to reference the address space after gfs2 had freed the superblock
that contained it.
This patch adds a call to truncate_inode_pages_final for sd_aspace, thus
avoiding the use-after-free.

return_all_reservations, but return_all_reservations still dereferences
rgd->rd_bits in __rs_deltree. Fix that by moving the call to kfree below the
call to return_all_reservations.

K2G devices still only use single parameter for power-domains property,
so check for this properly in the driver. Without this, every peripheral
fails to probe resulting in boot failure.

VFIO allows a device driver to resolve a fault by mapping a MMIO
range. This can be subsequently result in user_mem_abort() to
try and compute a huge mapping based on the MMIO pfn, which is
a sure recipe for things to go wrong.
Instead, force a PTE mapping when the pfn faulted in has a device
mapping.

Although huge pages can be created out of multiple contiguous PMDs
or PTEs, the corresponding sizes are not supported at Stage-2 yet.
Instead of failing the mapping, fall back to the nearer supported
mapping size (CONT_PMD to PMD and CONT_PTE to PTE respectively).

Pull networking fixes from Jakub Kicinski:
"Current release regressions:
- r8169: fix forced threading conflicting with other shared
interrupts; we tried to fix the use of raise_softirq_irqoff from an
IRQ handler on RT by forcing hard irqs, but this driver shares
legacy PCI IRQs so drop the _irqoff() instead
- tipc: fix memory leak caused by a recent syzbot report fix to
tipc_buf_append()
Current release - bugs in new features:
- devlink: Unlock on error in dumpit() and fix some error codes
- net/smc: fix null pointer dereference in smc_listen_decline()
Previous release - regressions:
- tcp: Prevent low rmem stalls with SO_RCVLOWAT.
- net: protect tcf_block_unbind with block lock
- ibmveth: Fix use of ibmveth in a bridge; the self-imposed filtering
to only send legal frames to the hypervisor was too strict
- net: hns3: Clear the CMDQ registers before unmapping BAR region;
incorrect cleanup order was leading to a crash
- bnxt_en - handful of fixes to fixes:
- Send HWRM_FUNC_RESET fw command unconditionally, even if there
are PCIe errors being reported
- Check abort error state in bnxt_open_nic().
- Invoke cancel_delayed_work_sync() for PFs also.
- Fix regression in workqueue cleanup logic in bnxt_remove_one().
- mlxsw: Only advertise link modes supported by both driver and
device, after removal of 56G support from the driver 56G was not
cleared from advertised modes
- net/smc: fix suppressed return code
Previous release - always broken:
- netem: fix zero division in tabledist, caused by integer overflow
- bnxt_en: Re-write PCI BARs after PCI fatal error.
- cxgb4: set up filter action after rewrites
- net: ipa: command payloads already mapped
Misc:
- s390/ism: fix incorrect system EID, it's okay to change since it
was added in current release
- vsock: use ns_capable_noaudit() on socket create to suppress false
positive audit messages"

stage2_pte_cacheable() tries to figure out whether the mapping installed
in its 'pte' parameter is cacheable or not. Unfortunately, it fails
miserably because it extracts the memory attributes from the entry using
FIELD_GET(), which returns the attributes shifted down to bit 0, but then
compares this with the unshifted value generated by the PAGE_S2_MEMATTR()
macro.
A direct consequence of this bug is that cache maintenance is silently
skipped, which in turn causes 32-bit guests to crash early on when their
set/way maintenance is trapped but not emulated correctly.
Fix the broken masks by avoiding the use of FIELD_GET() altogether.

The new calling convention says that pointers coming from the SMCCC
interface are turned into their HYP version in the host HVC handler.
However, there is still a stray kern_hyp_va() in the TLB invalidation
code, which could result in a corrupted pointer.
Drop the spurious conversion.
