613b065ca3 net: stmmac: fix dma queue left shift overflow issue
When queue number is > 4, left shift overflows due to 32 bits
integer variable. Mask calculation is wrong for MTL_RXQ_DMA_MAP1.

If CONFIG_UBSAN is enabled, kernel dumps below warning:

76c16d3e19 net: stmmac: switch to use interrupt for hw crosstimestamping
Using current implementation of polling mode, there is high chances we
will hit into timeout error when running phc2sys. Hence, update the
implementation of hardware crosstimestamping to use the MAC interrupt
service routine instead of polling for TSIS bit in the MAC Timestamp
Interrupt Status register to be set.

ced7866db3 drm/i915/ttm: fix 32b build
Since segment_pages is no longer a compile time constant, it looks the
DIV_ROUND_UP(node->size, segment_pages) breaks the 32b build. Simplest
is just to use the ULL variant, but really we should need not need more
than u32 for the page alignment (also we are limited by that due to the
sg->length type), so also make it all u32.

4b335e1e0d perf trace: Fix SIGSEGV when processing syscall args
On powerpc, 'perf trace' is crashing with a SIGSEGV when trying to
process a perf.data file created with 'perf trace record -p':

  #0  0x00000001225b8988 in syscall_arg__scnprintf_augmented_string <snip> at builtin-trace.c:1492
  #1  syscall_arg__scnprintf_filename <snip> at builtin-trace.c:1492
  #2  syscall_arg__scnprintf_filename <snip> at builtin-trace.c:1486
  #3  0x00000001225bdd9c in syscall_arg_fmt__scnprintf_val <snip> at builtin-trace.c:1973
  #4  syscall__scnprintf_args <snip> at builtin-trace.c:2041
  #5  0x00000001225bff04 in trace__sys_enter <snip> at builtin-trace.c:2319

That points to the below code in tools/perf/builtin-trace.c:
	/*
	 * If this is raw_syscalls.sys_enter, then it always comes with the 6 possible
	 * arguments, even if the syscall being handled, say "openat", uses only 4 arguments
	 * this breaks syscall__augmented_args() check for augmented args, as we calculate
	 * syscall->args_size using each syscalls:sys_enter_NAME tracefs format file,
	 * so when handling, say the openat syscall, we end up getting 6 args for the
	 * raw_syscalls:sys_enter event, when we expected just 4, we end up mistakenly
	 * thinking that the extra 2 u64 args are the augmented filename, so just check
	 * here and avoid using augmented syscalls when the evsel is the raw_syscalls one.
	 */
	if (evsel != trace->syscalls.events.sys_enter)
		augmented_args = syscall__augmented_args(sc, sample, &augmented_args_size, trace->raw_augmented_syscalls_args_size);

As the comment points out, we should not be trying to augment the args
for raw_syscalls. However, when processing a perf.data file, we are not
initializing those properly. Fix the same.

  There's a problem with sleeping under spinlock, when xa_insert could

  problem that we unfortunately did not discover during review.

  I'm sorry to do such change at rc6 time but the revert is IMO the
  safer option, there are patches to use mutex instead of the spin locks
  but that would need more testing. The revert branch has been tested on
  a few setups, all seem ok.

  The conversion to xarray will be revisited in the future"

829d680e82 random: cap jitter samples per bit to factor of HZ
Currently the jitter mechanism will require two timer ticks per
iteration, and it requires N iterations per bit. This N is determined
with a small measurement, and if it's too big, it won't waste time with
jitter entropy because it'd take too long or not have sufficient entropy
anyway.

With the current max N of 32, there are large timeouts on systems with a
small CONFIG_HZ. Rather than set that maximum to 32, instead choose a
factor of CONFIG_HZ. In this case, 1/30 seems to yield sane values for
different configurations of CONFIG_HZ.

11052589cf tcp/udp: Make early_demux back namespacified.
Commit e21145a987 ("ipv4: namespacify ip_early_demux sysctl knob") made
it possible to enable/disable early_demux on a per-netns basis.  Then, we
introduced two knobs, tcp_early_demux and udp_early_demux, to switch it for
TCP/UDP in commit dddb64bcb3 ("net: Add sysctl to toggle early demux for
tcp and udp").  However, the .proc_handler() was wrong and actually
disabled us from changing the behaviour in each netns.

We can execute early_demux if net.ipv4.ip_early_demux is on and each proto
.early_demux() handler is not NULL.  When we toggle (tcp|udp)_early_demux,
the change itself is saved in each netns variable, but the .early_demux()
handler is a global variable, so the handler is switched based on the
init_net's sysctl variable.  Thus, netns (tcp|udp)_early_demux knobs have
nothing to do with the logic.  Whether we CAN execute proto .early_demux()
is always decided by init_net's sysctl knob, and whether we DO it or not is
by each netns ip_early_demux knob.

This patch namespacifies (tcp|udp)_early_demux again.  For now, the users
of the .early_demux() handler are TCP and UDP only, and they are called
directly to avoid retpoline.  So, we can remove the .early_demux() handler
from inet6?_protos and need not dereference them in ip6?_rcv_finish_core().
If another proto needs .early_demux(), we can restore it at that time.

Pull drm fixes from Dave Airlie:
 "This is the regular fixes pull for this week. This has a bunch of
  amdgpu fixes, major one reverts the buddy allocator until it can be
  tested more, otherwise just small ones, then i915 has a bunch of
  fixes.

  The outstanding firmware regressions reported by phoronix will
  hopefully be dealt with ASAP.

  amdgpu:
   - revert buddy allocator support for now
   - DP MST blank screen fix for specific platforms
   - MEC firmware check fix for GC 10.3.7
   - Deep color fix for DCE
   - Fix possible divide by 0
   - Coverage blend mode fix
   - Fix cursor only commit timestamps

  i915:
   - Selftest fix
   - TTM fix sg_table construction
   - Error return fixes
   - Fix a performance regression related to waitboost
   - Fix GT resets"

7962918160 KVM: emulate: do not adjust size of fastop and setcc subroutines
Instead of doing complicated calculations to find the size of the subroutines
(which are even more complicated because they need to be stringified into
an asm statement), just hardcode to 16.

It is less dense for a few combinations of IBT/SLS/retbleed, but it has
the advantage of being really simple.

Biao Huang says:

====================
stmmac: dwmac-mediatek: fix clock issue

changes in v5:
1. add reivewd-by as Matthias's comments.
2. fix "warning: unused variable 'ret' [-Wunused-variable]" as Jakub's comments

changes in v4:
1. improve commit message and test ko insertion/remove as Matthias's comments.
2. add patch "net: stmmac: fix pm runtime issue in stmmac_dvr_remove()" to
   fix vlan filter deletion issue.
3. add patch "net: stmmac: fix unbalanced ptp clock issue in suspend/resume flow"
   to fix unbalanced ptp clock issue in suspend/resume flow.

changes in v3:
1. delete mediatek_dwmac_exit() since there is no operation in it,
as Matthias's comments.

changes in v2:
1. clock configuration is still needed in probe,
and invoke mediatek_dwmac_clks_config() instead.
2. update commit message.

v1:
remove duplicated clock configuration in init/exit.

f4c7d8948e net: stmmac: fix unbalanced ptp clock issue in suspend/resume flow
Current stmmac driver will prepare/enable ptp_ref clock in
stmmac_init_tstamp_counter().

The stmmac_pltfr_noirq_suspend will disable it once in suspend flow.

But in resume flow,
	stmmac_pltfr_noirq_resume --> stmmac_init_tstamp_counter
	stmmac_resume --> stmmac_hw_setup --> stmmac_init_ptp --> stmmac_init_tstamp_counter
ptp_ref clock reference counter increases twice, which leads to unbalance
ptp clock when resume back.

Move ptp_ref clock prepare/enable out of stmmac_init_tstamp_counter to fix it.

Fixes: 0735e639f1 ("net: stmmac: skip only stmmac_ptp_register when resume from suspend")
