In case the optimization fails, we leak new-ly created trampoline
vma mapping (in case we just created it), let's unmap it.

Removing struct uprobe_trampoline object and it's tracking code,
because it's not needed. We can do same thing directly on top of
struct vm_area_struct objects.
This makes the code simpler and allows easy propagation of the
trampoline vma object into child process in following change.
Note the original code called destroy_uprobe_trampoline if the
optimiation failed, but it only freed the struct uprobe_trampoline
object, not the vma. The new vma leak is fixed in following change.

Pull mod_devicetable.h header split from Uwe Kleine-König:
"Split <linux/mod_devicetable.h> in per subsystem headers
<linux/mod_devicetable.h> is included transitively in nearly every
driver in an x86_64 allmodconfig build of v7.1:
$ find drivers -name \*.o -not -name \*.mod.o | wc -l
21330
$ find drivers -name \*.o.cmd -not -name \*.mod.o.cmd | xargs grep -l mod_devicetable.h | wc -l
17038
The result of this mixture of different and unrelated subsystem
details is that even when touching an obscure device id struct most of
the kernel needs to be recompiled. Given that each driver typically
only needs one or two of these structures, splitting into per
subsystem headers and only including what is really needed reduces the
amount of needed recompilation.
This split is implemented in the first commit and then after some
preparatory work in the following commits, the last two replace
includes of <linux/mod_devicetable.h> by the actually needed more
specific headers.
There are still a few instances left, but the ones with high impact
(that is in headers that are used a lot) and the easy ones (.c files)
are handled. These remaining includes will be addressed during the
next merge window"

(headers)
<linux/mod_devicetable.h> is included in a many files:
$ git grep '<linux/mod_devicetable.h>' ef0c9f75a195 | wc -l
1598
; some of them are widely used headers. To stop mixing up different and
unrelated driver( type)s let the subsystem headers only use the subset
of the recently split <linux/mod_devicetable.h> that are relevant for
them.
The fallout (I hope) is addressed in the previous commits that handle
sources relying on e.g. <linux/i2c.h> pulling in the full legacy header
and thus providing pci_device_id.

Currently <linux/compiler.h> isn't included at all (not even
transitively) in <asm/ptrace.h>.
arch/parisc/kernel/asm-offsets.c just happens to include the following
chain of includes before <asm/ptrace.h>:
<linux/sched.h>
-> <asm/processor.h>
-> <asm/hardware.h>
-> <linux/mod_devicetable.h>
-> <linux/uuid.h>
-> <linux/string.h>
-> <linux/compiler.h>
. That chain will be broken, because in one of the next commits
<asm/hardware.h> is changed to only include <linux/device-id/parisc.h>
instead of <linux/mod_devicetable.h>. So to ensure
arch/parisc/kernel/asm-offsets.c knows about unlikely() even after that
change, #include <linux/compiler.h> explicitly.

Traditionally <linux/mod_devicetable.h> was a header defining a plethora
of structs, among them struct cpu_features. This was split now with the
objective that only the relevant bits are included.
Currently <linux/mod_devicetable.h> is transitively included in
arch/loongarch/kvm/main.c via:
arch/loongarch/kvm/main.c ->
<linux/kvm_host.h> ->
<linux/entry-virt.h> ->
<linux/resume_user_mode.h> ->
<linux/memcontrol.h> ->
<linux/cgroup.h> ->
<linux/kernel_stat.h> ->
<linux/interrupt.h> ->
<linux/hardirq> ->
<asm/hardirq.h> ->
<linux/irq.h> ->
<asm/irq.h> ->
<linux/irqdomain.h> ->
<linux/of.h> ->
<linux/mod_devicetable.h>
To keep struct cpu_features available once <linux/of.h> stops including
<linux/mod_devicetable.h>, include it here explicitly.

The syscall trace path reloads syscall arguments from pt_regs before
calling the syscall handler. On C-SKY ABIv2, the 5th and 6th syscall
arguments are prepared as stack arguments before invoking syscallid.
The current code adjusts sp before loading LSAVE_A4 and LSAVE_A5. Since
those offsets are relative to the original pt_regs base, loading them
after changing sp fetches the wrong slots. As a result, traced syscalls
that use the 5th or 6th argument may receive corrupted arguments.
This is visible with mmap2(), which takes six arguments. A small
PTRACE_SYSCALL reproducer opens a file and maps one page with:
mmap(NULL, 4096, PROT_READ | PROT_EXEC, MAP_PRIVATE, fd, 0)
Before the fix, the traced child fails the mmap and exits with 12.
After the fix, the mapping succeeds and the child exits with 0.
Fix the trace path by loading a4/a5 from pt_regs before changing sp.
Tested on: ck860f, linux-4.19.15, C-SKY abiv2
Fixes: e0bbb53843b5 ("csky: Fixup abiv2 syscall_trace break a4 & a5")

The default msi-map from sm8550.dtsi is deleted for both pcie0 and
pcie1. The QPS615 PCIe switch on each port exposes more than two
devices (1 USP + 3 DSPs), but Gunyah currently limits ITS device
mappings to two per root complex to save memory. With msi-map
present, the ITS MAPD command times out.
Deleting msi-map causes the DWC controller to fall back to its
internal iMSI-RX module, which handles MSIs without this limitation.

Enable secondary USB controller in host mode on lemans EVK Platform.
Secondary USB controller is connected to a Genesys Logic USB HUB GL3590
having 4 ports. The ports of hub that are present on lemans EVK standalone
board are used as follows:-
1) port-1 is connected to HD3SS3220 Type-C port controller.
2) port-4 is used for the M.2 E key on corekit. Standard core kit uses UART
for Bluetooth. This port is to be used only if user optionally replaces the
WiFi card with the NFA765 chip which uses USB for Bluetooth.
Remaining 2 ports will become functional when the interface plus mezzanine
board is stacked on top of corekit:
3) port-2 is connected to another hub which is present on the mezz through
which 4 type-A ports are connected.
4) port-3 is used for the M.2 B key for a 5G card when the mezz is
connected.

IRQ_TYPE_xxx flags are not correct in the context of GPIO flags.
These are simple defines so they could be used in DTS but they will not
have the same meaning: IRQ_TYPE_LEVEL_LOW = 8 = GPIO_TRANSITORY.
Correct the touchscreen irq-gpios to use proper flags, assuming the
author of the code wanted similar logical behavior:
IRQ_TYPE_LEVEL_LOW => GPIO_ACTIVE_LOW

Add the missing Broadcom Wi-Fi and Bluetooth child nodes for the
9Tripod X3568 v4 board.
The Bluetooth subnode is attached to uart8 with hardware flow control
enabled via RTS/CTS pins.
The Wi-Fi subnode is connected via the sdmmc2 bus.
Additionally, change the status of the i2s3_2ch node to "disabled"
since the required rk3568-codec-digital driver for Bluetooth audio
is currently unavailable in the mainline tree.

9Tripod X3568 v4
The 'gpio' property for fixed regulators has been deprecated in favor
of the plural 'gpios' form according to the regulator-fixed binding.
Update the USB host and USB OTG fixed regulators for the 9Tripod X3568 v4
board to use the modern 'gpios' property to conform with current
devicetree binding standards.

Call xbc_prepend_embedded_cmdline() in setup_arch() right after the
CONFIG_CMDLINE merge and before strscpy(command_line, ...) so the
build-time-rendered embedded bootconfig "kernel" subtree is part of
boot_command_line by the time parse_early_param() runs. early_param()
handlers (mem=, earlycon=, loglevel=, ...) now see values supplied via
CONFIG_BOOT_CONFIG_EMBED_FILE without parsing bootconfig at runtime.
Gate the prepend on the same opt-in the runtime parser uses: prepend
when "bootconfig" is present on the command line, or when
CONFIG_BOOT_CONFIG_FORCE is set. Detect it with parse_args(), exactly
as setup_boot_config() does, so both agree on what counts as opt-in:
any "bootconfig" key regardless of value (bare, =0, =1, ...), and only
before the "--" that separates init arguments. Sharing the parser keeps
the early and late paths from diverging -- e.g. "bootconfig=0" or a
"-- bootconfig" meant for init must not apply the embedded keys early
while the runtime parser skips them.
The prepend necessarily runs before setup_boot_config() detects an
initrd bootconfig, so an initrd cannot override the embedded "kernel"
keys for early_param(). This is intentional: the embedded cmdline acts
like a build-time CONFIG_CMDLINE. An initrd bootconfig's "kernel" keys
never reached early_param() anyway (they apply late via
extra_command_line), so nothing is lost -- the initrd keys still apply
late, with last-wins keeping the embedded values in effect.

In the unregister path we use __in_uprobe_trampoline check with
current->mm for the VMA lookup, which is wrong, because we are
in the tracer context, not the traced process.
Add mm_struct pointer argument to __in_uprobe_trampoline and
changing related callers to pass proper mm_struct pointer.

Commit 93d7356e4b30 ("arm64: sysreg: Describe ID_AA64DFR2_EL1 fields")
encodes the FEAT_BWE2 value of the BWE field as '0b0002'. Binary
literals only accept the digits 0 and 1, so the intended value is 2,
i.e. 0b0010.
The macro generated by gen-sysreg.awk currently expands to
#define ID_AA64DFR2_EL1_BWE_FEAT_BWE2 UL(0b0002)
is not legal C and would fail to compile if any in-tree code referenced
it. At present no caller uses this enum value, so the kernel still
builds cleanly, but the bug is latent.
Fix the typo by using the correct binary literal 0b0010.
