The bnxt_coredump_record structure is very long, causing a warning
about possible stack overflow on 32-bit architectures:
drivers/net/ethernet/broadcom/bnxt/bnxt_ethtool.c: In function 'bnxt_get_coredump':
drivers/net/ethernet/broadcom/bnxt/bnxt_ethtool.c:2989:1: error: the frame size of 1188 bytes is larger than 1024 bytes [-Werror=frame-larger-than=]
I could not see any reason to operate on an on-stack copy of the
structure before copying it back into the caller-provided buffer, which
also simplifies the code here.

The only remaining caller of this function is inside of an #ifdef
after another caller got removed. This causes a harmless warning
in some configurations:
drivers/net/ethernet/broadcom/bcmsysport.c:1068:13: error: 'bcm_sysport_resume_from_wol' defined but not used [-Werror=unused-function]
Removing the #ifdef around the PM functions simplifies the code
and avoids the problem but letting the compiler drop the unused
functions silently.

The newly added suspend/resume functions cause a build warning
when CONFIG_PM is disabled:
drivers/net/ethernet/stmicro/stmmac/stmmac_pci.c:324:12: error: 'stmmac_pci_resume' defined but not used [-Werror=unused-function]
drivers/net/ethernet/stmicro/stmmac/stmmac_pci.c:306:12: error: 'stmmac_pci_suspend' defined but not used [-Werror=unused-function]
Mark them as __maybe_unused so gcc can drop them silently.

Removing one of the callers of pppol2tp_session_get_sock caused a harmless
warning in some configurations:
net/l2tp/l2tp_ppp.c:142:21: 'pppol2tp_session_get_sock' defined but not used [-Wunused-function]
Rather than adding another #ifdef here, using a proper IS_ENABLED()
check makes the code more readable and avoids those warnings while
letting the compiler figure out for itself which code is needed.
This adds one pointer for the unused show() callback in struct
l2tp_session, but that seems harmless.

The utsname()->nodename string may be 64 bytes long, and it gets
copied without the trailing nul byte into the shorter record->system_name,
as gcc now warns:
In file included from include/linux/bitmap.h:9,
from include/linux/ethtool.h:16,
from drivers/net/ethernet/broadcom/bnxt/bnxt_ethtool.c:13:
In function 'strncpy',
inlined from 'bnxt_fill_coredump_record' at drivers/net/ethernet/broadcom/bnxt/bnxt_ethtool.c:2863:2:
include/linux/string.h:254:9: error: '__builtin_strncpy' output truncated before terminating nul copying as many bytes from a string as its length [-Werror=stringop-truncation]
Using strlcpy() at least avoids overflowing the destination buffer
and adds proper nul-termination. It may still truncate long names
though, which probably can't be solved here.

Those #ifdef checks are hard to get right, replace them all with
IS_ENABLED() checks that leave the same code visible to the compiler
but let it optimize out the unused bits based on the configuration.

Pull vfs icache updates from Al Viro:
- NFS mkdir/open_by_handle race fix
- analogous solution for FUSE, replacing the one currently in mainline
- new primitive to be used when discarding halfway set up inodes on
failed object creation; gives sane warranties re icache lookups not
returning such doomed by still not freed inodes. A bunch of
filesystems switched to that animal.
- Miklos' fix for last cycle regression in iget5_locked(); -stable will
need a slightly different variant, unfortunately.
- misc bits and pieces around things icache-related (in adfs and jfs).
* 'work.mkdir' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs:
jfs: don't bother with make_bad_inode() in ialloc()
adfs: don't put inodes into icache
new helper: inode_fake_hash()
vfs: don't evict uninitialized inode
jfs: switch to discard_new_inode()
ext2: make sure that partially set up inodes won't be returned by ext2_iget()
udf: switch to discard_new_inode()

Pull vfs open-related updates from Al Viro:
- "do we need fput() or put_filp()" rules are gone - it's always fput()
now. We keep track of that state where it belongs - in ->f_mode.
- int *opened mess killed - in finish_open(), in ->atomic_open()
instances and in fs/namei.c code around do_last()/lookup_open()/atomic_open().
- alloc_file() wrappers with saner calling conventions are introduced
(alloc_file_clone() and alloc_file_pseudo()); callers converted, with
much simplification.
- while we are at it, saner calling conventions for path_init() and
link_path_walk(), simplifying things inside fs/namei.c (both on
open-related paths and elsewhere).
* 'work.open3' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: (40 commits)
few more cleanups of link_path_walk() callers
allow link_path_walk() to take ERR_PTR()
make path_init() unconditionally paired with terminate_walk()
document alloc_file() changes
make alloc_file() static
do_shmat(): grab shp->shm_file earlier, switch to alloc_file_clone()
new helper: alloc_file_clone()
create_pipe_files(): switch the first allocation to alloc_file_pseudo()
anon_inode_getfile(): switch to alloc_file_pseudo()
hugetlb_file_setup(): switch to alloc_file_pseudo()

net_sched: Fix two tc_index filter init issues
These two patches fix two tc_index filter init issues. The first one fixes
missing exts info in new filter, which will cause NULL pointer dereference
when delete tcindex filter. The second one fixes missing res info when create
new filter, which will make filter unbind failed.

This is because we didn't update f->result.res when create new filter. Then in
tcindex_delete() -> tcf_unbind_filter(), we will failed to find out the res
and unbind filter, which will trigger the WARN_ON() in cbq_destroy_class().
Fix it by updating f->result.res when create new filter.

This is because in tcindex_set_parms, when there is no old_r, we set new
exts to cr.exts. And we didn't set it to filter when r == &new_filter_result.
Then in tcindex_delete() -> tcf_exts_get_net(), we will get NULL pointer
dereference as we didn't init exts.
Fix it by moving tcf_exts_change() after "if (old_r && old_r != r)" check.
Then we don't need "cr" as there is no errout after that.

git://git.kernel.org/pub/scm/linux/kernel/git/mips/linux
Pull MIPS updates from Paul Burton:
"Here are the main MIPS changes for 4.19.
An overview of the general architecture changes:
- Massive DMA ops refactoring from Christoph Hellwig (huzzah for
deleting crufty code!).
- We introduce NT_MIPS_DSP & NT_MIPS_FP_MODE ELF notes &
corresponding regsets to expose DSP ASE & floating point mode state
respectively, both for live debugging & core dumps.
- We better optimize our code by hard-coding cpu_has_* macros at
compile time where their values are known due to the ISA revision
that the kernel build is targeting.
- The EJTAG exception handler now better handles SMP systems, where
it was previously possible for CPUs to clobber a register value
saved by another CPU.
- Our implementation of memset() gained a couple of fixes for MIPSr6
systems to return correct values in some cases where stores fault.
- We now implement ioremap_wc() using the uncached-accelerated cache
coherency attribute where supported, which is detected during boot,
and fall back to plain uncached access where necessary. The
MIPS-specific (and unused in tree) ioremap_uncached_accelerated() &
ioremap_cacheable_cow() are removed.
- The prctl(PR_SET_FP_MODE, ...) syscall is better supported for SMP
systems by reworking the way we ensure remote CPUs that may be
running threads within the affected process switch mode.
- Systems using the MIPS Coherence Manager will now set the
MIPS_IC_SNOOPS_REMOTE flag to avoid some unnecessary cache
maintenance overhead when flushing the icache.
- A few fixes were made for building with clang/LLVM, which now
sucessfully builds kernels for many of our platforms.
- Miscellaneous cleanups all over.
And some platform-specific changes:
- ar7 gained stubs for a few clock API functions to fix build
failures for some drivers.
- ath79 gained support for a few new SoCs, a few fixes & better
gpio-keys support.
- Ci20 now exposes its SPI bus using the spi-gpio driver.
- The generic platform can now auto-detect a suitable value for
PHYS_OFFSET based upon the memory map described by the device tree,
allowing us to avoid wasting memory on page book-keeping for
systems where RAM starts at a non-zero physical address.
- Ingenic systems using the jz4740 platform code now link their
vmlinuz higher to allow for kernels of a realistic size.
- Loongson32 now builds the kernel targeting MIPSr1 rather than
MIPSr2 to avoid CPU errata.
- Loongson64 gains a couple of fixes, a workaround for a write
buffering issue & support for the Loongson 3A R3.1 CPU.
- Malta now uses the piix4-poweroff driver to handle powering down.
- Microsemi Ocelot gained support for its SPI bus & NOR flash, its
second MDIO bus and can now be supported by a FIT/.itb image.
- Octeon saw a bunch of header cleanups which remove a lot of
duplicate or unused code"

- A large rework of the early boot code that will make life easier
for KASAN and KASLR. With the rework the bootable uncompressed
image is not generated anymore, only the bzImage is available. For
debuggung purposes the new "no compression" option is used.
- Re-enable the gcc plugins as the issue with the latent entropy
plugin is solved with the early boot code rework.

+ Detect the etoken facility and remove expolines automatically.
+ Add expolines to a few more indirect branches.
- A rewrite of the common I/O layer trace points to make them
consumable by 'perf stat'.
- Add support for format-3 PCI function measurement blocks.

Pull x86 cache QoS (RDT/CAR) updates from Thomas Gleixner:
"Add support for pseudo-locked cache regions.
Cache Allocation Technology (CAT) allows on certain CPUs to isolate a
region of cache and 'lock' it. Cache pseudo-locking builds on the fact
that a CPU can still read and write data pre-allocated outside its
current allocated area on cache hit. With cache pseudo-locking data
can be preloaded into a reserved portion of cache that no application
can fill, and from that point on will only serve cache hits. The cache
pseudo-locked memory is made accessible to user space where an
application can map it into its virtual address space and thus have a
region of memory with reduced average read latency.
The locking is not perfect and gets totally screwed by WBINDV and
similar mechanisms, but it provides a reasonable enhancement for
certain types of latency sensitive applications.
The implementation extends the current CAT mechanism and provides a
generally useful exclusive CAT mode on which it builds the extra
pseude-locked regions"

[Why]
A null pointer deference can occur if crtc is null in
amdgpu_dm_crtc_handle_crc_irq. This can happen if get_crtc_by_otg_inst
returns NULL during dm_crtc_high_irq, leading to a hang in some IGT
test cases.
[How]
Check that CRTC is non-null before accessing its fields.

[why]
Older ASICs require both phys_id and connector_id
to execute bios command table. If we are not passing the
right connector_id - it can lead to a black screen.
[how]
Set connector_obj_id when executing vbios command table

[why]
We are disabling clock source while other pipes are still using
it, because we don't verify the number of pipes that share it.
[how]
- Adding a function in resources to return the number of pipes
sharing the clock source.
- Checking that no one is sharing the clock source before disabling

[why]
HDMI and DVI share the same PHY clock and single link
DVI and HDMI both use 4 lanes, so they should be allowed
to be sharing the same clock source if all other parameters
are satisfied.
[how]
Change a check for general DVI to Dual DVI.

[Why]
DOUBLE_BUFFER_EN bit is getting cleared before enable blanking.
That leads to CRTC_BLANK_DATA_EN is getting updated immediately.
[How]
Get DOUBLE_BUFFER_EN bit set, the same as DCE110.
