Where 0x35d is a static call site that's turned into a conditional

In order to re-write Jcc.d32 instructions text_poke_bp() needs to be
taught about them.
The biggest hurdle is that the whole machinery is currently made for 5
byte instructions and extending this would grow struct text_poke_loc
which is currently a nice 16 bytes and used in an array.
However, since text_poke_loc contains a full copy of the (s32)
displacement, it is possible to map the Jcc.d32 2 byte opcodes to
Jcc.d8 1 byte opcode for the int3 emulation.
This then leaves the replacement bytes; fudge that by only storing the
last 5 bytes and adding the rule that 'length == 6' instruction will
be prefixed with a 0x0f byte.

The PSCI suspend code is currently instrumentable, which is not safe as
instrumentation (e.g. ftrace) may try to make use of RCU during idle
periods when RCU is not watching.
To fix this we need to ensure that psci_suspend_finisher() and anything
it calls are not instrumented. We can do this fairly simply by marking
psci_suspend_finisher() and the psci*_cpu_suspend() functions as
noinstr, and the underlying helper functions as __always_inline.
When CONFIG_DEBUG_VIRTUAL=y, __pa_symbol() can expand to an out-of-line
instrumented function, so we must use __pa_symbol_nodebug() within
psci_suspend_finisher().
The raw SMCCC invocation functions are written in assembly, and are not
subject to compiler instrumentation.

memblock_merge_regions() is called after regions have been modified to
merge the neighboring compatible regions. That will check all regions
but most checks are useless.
Most of the time we only insert one or a few new regions, or modify one or
a few regions. At this time, we don't need to check all the regions. We
only need to check the changed regions, because other not related regions
cannot be merged.
Add two parameters to memblock_merge_regions() to indicate the lower and
upper boundary to scan.
Debug code that counts the number of total iterations in
memblock_merge_regions(), like for instance
void memblock_merge_regions(struct memblock_type *type)
{
static int iteration_count = 0;
static int max_nr_regions = 0;
max_nr_regions = max(max_nr_regions, (int)type->cnt);
...
while () {
iteration_count++;
...
}
pr_info("iteration_count: %d max_nr_regions %d", iteration_count,
max_nr_regions);
}
Produces the following numbers on a physical machine with 1T of memory:
before: [2.472243] iteration_count: 45410 max_nr_regions 178
after: [2.470869] iteration_count: 923 max_nr_regions 176
The actual startup speed seems to change little, but it does reduce the

When using a xfrm interface in a bridged setup (the outgoing device is
bridged), the incoming packets in the xfrm interface are only tracked
in the outgoing direction.
$ brctl show
bridge name interfaces
br_eth1 eth1
$ conntrack -L
tcp 115 SYN_SENT src=192... dst=192... [UNREPLIED] ...
If br_netfilter is enabled, the first (encrypted) packet is received onR
eth1, conntrack hooks are called from br_netfilter emulation which
allocates nf_bridge info for this skb.
If the packet is for local machine, skb gets passed up the ip stack.
The skb passes through ip prerouting a second time. br_netfilter
ip_sabotage_in supresses the re-invocation of the hooks.
After this, skb gets decrypted in xfrm layer and appears in
network stack a second time (after decryption).
Then, ip_sabotage_in is called again and suppresses netfilter
hook invocation, even though the bridge layer never called them
for the plaintext incarnation of the packet.
Free the bridge info after the first suppression to avoid this.
I was unable to figure out where the regression comes from, as far as i
can see br_netfilter always had this problem; i did not expect that skb
is looped again with different headers.

Almost(?) every i.MX variant has clk mux for ethernet (rgmii/rmii) reference
clock located in the GPR1 register. So far this clk is configured in
different ways:
- mach-imx6q is doing mux configuration based on ptp vs enet_ref clk
comparison.
- mach-imx7d is setting mux to PAD for all boards
- mach-imx6ul is setting mux to internal clock for all boards.
Since we have imx7d and imx6ul board variants which do not work with
configurations forced by kernel mach code, we need to implement this clk
mux properly as part of the clk framework. Which is done by this patch.

While we do have GT oriented print macros, add few more GuC
specific to have common look and feel across all messages
related to the GuC and to avoid chasing the gt pointer.
We will use these macros shortly in upcoming patches.

reg_base and reg_downshift currently don't have any effect if used with
a regmap_bus or regmap_config which only offers single register
operations (ie. reg_read, reg_write and optionally reg_update_bits).
Fix that and take them into account also for regmap_bus with only
reg_read and read_write operations by applying reg_base and
reg_downshift in _regmap_bus_reg_write, _regmap_bus_reg_read.
Also apply reg_base and reg_downshift in _regmap_update_bits, but only
in case the operation is carried out with a reg_update_bits call
defined in either regmap_bus or regmap_config.
Fixes: 0074f3f2b1 ("regmap: allow a defined reg_base to be added to every address")
Fixes: 86fc59ef81 ("regmap: add configurable downshift for addresses")

Since clock stop causes bus reset on Intel controllers, we need
to wait for the debounce interval on resume, to ensure all the
interrupt status registers are set correctly.

idle_bias_on was set because cs42l42 has a "VMID" type pseudo-midrail
supply (named FILT+), and these typically take a long time to charge.
But the driver never enabled pm_runtime so it would never have powered-
down the cs42l42 anyway.
In fact, FILT+ can charge to operating voltage within 12.5 milliseconds
of enabling HP or ADC. This time is already covered by the startup
delay of the HP/ADC.
The datasheet warning about FILT+ taking up to 1 second to charge only
applies in the special cases that either the PLL is started or
DETECT_MODE set to non-zero while both HP and ADC are off. The driver
never does either of these.
Removing idle_bias_on allows the Soundwire host controller to suspend
if there isn't a snd_soc_jack handler registered.
