Marc Zyngier 2a1a3fa0f2 kallsyms: Don't let kallsyms_lookup_size_offset() fail on retrieving the first symbol
An arm64 kernel configured with

  CONFIG_KPROBES=y
  CONFIG_KALLSYMS=y
  # CONFIG_KALLSYMS_ALL is not set
  CONFIG_KALLSYMS_BASE_RELATIVE=y

reports the following kprobe failure:

  [    0.032677] kprobes: failed to populate blacklist: -22
  [    0.033376] Please take care of using kprobes.

It appears that kprobe fails to retrieve the symbol at address
0xffff000010081000, despite this symbol being in System.map:

  ffff000010081000 T __exception_text_start

This symbol is part of the first group of aliases in the
kallsyms_offsets array (symbol names generated using ugly hacks in
scripts/kallsyms.c):

  kallsyms_offsets:
          .long   0x1000 // do_undefinstr
          .long   0x1000 // efi_header_end
          .long   0x1000 // _stext
          .long   0x1000 // __exception_text_start
          .long   0x12b0 // do_cp15instr

Looking at the implementation of get_symbol_pos(), it returns the
lowest index for aliasing symbols. In this case, it return 0.

But kallsyms_lookup_size_offset() considers 0 as a failure, which
is obviously wrong (there is definitely a valid symbol living there).
In turn, the kprobe blacklisting stops abruptly, hence the original
error.

A CONFIG_KALLSYMS_ALL kernel wouldn't fail as there is always
some random symbols at the beginning of this array, which are never
looked up via kallsyms_lookup_size_offset.

Fix it by considering that get_symbol_pos() is always successful
(which is consistent with the other uses of this function).

Lyude Paul 32f0a98265 drm/i915: Call dma_set_max_seg_size() in i915_driver_hw_probe()
Currently, we don't call dma_set_max_seg_size() for i915 because we
intentionally do not limit the segment length that the device supports.
However, this results in a warning being emitted if we try to map
anything larger than SZ_64K on a kernel with CONFIG_DMA_API_DEBUG_SG
enabled:

[    7.751926] DMA-API: i915 0000:00:02.0: mapping sg segment longer
than device claims to support [len=98304] [max=65536]
[    7.751934] WARNING: CPU: 5 PID: 474 at kernel/dma/debug.c:1220
debug_dma_map_sg+0x20f/0x340

This was originally brought up on
https://bugs.freedesktop.org/show_bug.cgi?id=108517 , and the consensus
there was it wasn't really useful to set a limit (and that dma-debug
isn't really all that useful for i915 in the first place). Unfortunately
though, CONFIG_DMA_API_DEBUG_SG is enabled in the debug configs for
various distro kernels. Since a WARN_ON() will disable automatic problem
reporting (and cause any CI with said option enabled to start
complaining), we really should just fix the problem.

Note that as me and Chris Wilson discussed, the other solution for this
would be to make DMA-API not make such assumptions when a driver hasn't
explicitly set a maximum segment size. But, taking a look at the commit
which originally introduced this behavior, commit 78c47830a5
("dma-debug: check scatterlist segments"), there is an explicit mention
of this assumption and how it applies to devices with no segment size:

	Conversely, devices which are less limited than the rather
	conservative defaults, or indeed have no limitations at all
	(e.g. GPUs with their own internal MMU), should be encouraged to
	set appropriate dma_parms, as they may get more efficient DMA
	mapping performance out of it.

So unless there's any concerns (I'm open to discussion!), let's just
follow suite and call dma_set_max_seg_size() with UINT_MAX as our limit
to silence any warnings.

Changes since v3:
* Drop patch for enabling CONFIG_DMA_API_DEBUG_SG in CI. It looks like
  just turning it on causes the kernel to spit out bogus WARN_ONs()
  during some igt tests which would otherwise require teaching igt to
  disable the various DMA-API debugging options causing this. This is
  too much work to be worth it, since DMA-API debugging is useless for
  us. So, we'll just settle with this single patch to squelch WARN_ONs()
  during driver load for users that have CONFIG_DMA_API_DEBUG_SG turned
  on for some reason.
* Move dma_set_max_seg_size() call into i915_driver_hw_probe() - Chris
  Wilson

Four drm_mm_node are used to reserve guest ggtt space, but some of them
may be skipped and not initialised due to space constraints in
intel_vgt_balloon(). If drm_mm_remove_node() is called with
uninitialized drm_mm_node, the above call trace occurs.

This patch check drm_mm_node's validity before calling
drm_mm_remove_node().

Ville Syrjälä ed5fa90660 drm/i915: Do not create a new max_bpc prop for MST connectors
We're not allowed to create new properties after device registration
so for MST connectors we need to either create the max_bpc property
earlier, or we reuse one we already have. Let's do the latter apporach
since the corresponding SST connector already has the prop and its
min/max are correct also for the MST connector.

The problem was highlighted by commit 4f5368b554 ("drm/kms:
Catch mode_object lifetime errors") which results in the following
spew:
[ 1330.878941] WARNING: CPU: 2 PID: 1554 at drivers/gpu/drm/drm_mode_object.c:45 __drm_mode_object_add+0xa0/0xb0 [drm]

Alexey Kardashevskiy ddfd151f3d KVM: PPC: Book3S: Fix incorrect guest-to-user-translation error handling
H_PUT_TCE_INDIRECT handlers receive a page with up to 512 TCEs from
a guest. Although we verify correctness of TCEs before we do anything
with the existing tables, there is a small window when a check in
kvmppc_tce_validate might pass and right after that the guest alters
the page of TCEs, causing an early exit from the handler and leaving
srcu_read_lock(&vcpu->kvm->srcu) (virtual mode) or lock_rmap(rmap)
(real mode) locked.

This fixes the bug by jumping to the common exit code with an appropriate
unlock.

Jiri Olsa 1345e2ee87 libperf: Add PERF_RECORD_MMAP 'struct mmap_event' to perf/event.h
Move the mmap_event event definition to libperf's event.h header
include.

In order to keep libperf simple, we switch 'u64/u32/u16/u8' types used
events to their generic '__u*' versions.

Perf added 'u*' types mainly to ease up printing __u64 values as stated
in the linux/types.h comment:

  /*
   * We define u64 as uint64_t for every architecture
   * so that we can print it with "%"PRIx64 without getting warnings.
   *
   * typedef __u64 u64;
   * typedef __s64 s64;
   */

Add  and use new PRI_lu64 and PRI_lx64 macros for that.  Use extra '_'
to ease up reading and differentiate them from standard PRI*64 macros.

Committer notes:

Fixup the PRI_l[ux]64 macros on 32-bit arches, conditionally defining it
with that extra 'l' modifier only on arches where __u64 is long long,
leaving it aside on 32-bit arches.

Kent Russell 23b7f6c41d drm/powerplay: Fix Vega20 power reading again
For the 40.46 SMU release, they changed CurrSocketPower to
AverageSocketPower, but this was changed back in 40.47 so just check if
it's 40.46 and make the appropriate change

Tested with 40.45, 40.46 and 40.47 successfully

Kent Russell 21649c0b6b drm/powerplay: Fix Vega20 Average Power value v4
The SMU changed reading from CurrSocketPower to AverageSocketPower, so
reflect this accordingly. This fixes the issue where Average Power
Consumption was being reported as 0 from SMU 40.46-onward

v2: Fixed headline prefix
v3: Add check for SMU version for proper compatibility
v4: Style fix

If writepage()/writepages() saw an error, but handled it without

Trond Myklebust 8f54c7a4ba NFS: Fix spurious EIO read errors
If the client attempts to read a page, but the read fails due to some
spurious error (e.g. an ACCESS error or a timeout, ...) then we need
to allow other processes to retry.
Also try to report errors correctly when doing a synchronous readpage.

This reverts commit a79f194aa4.
The mechanism for aborting I/O is racy, since we are not guaranteed that
the request is asleep while we're changing both task->tk_status and
task->tk_action.

If a connect or bind attempt returns EADDRINUSE, that means we want to

Similarly, ENOBUFS is not fatal, but just indicates a memory allocation
issue. Retry after a short delay.
