The Verdin family has a signal called sleep-moci which can be used to
turn off peripherals on the carrier board when the SoM goes into
suspend. So far we have hogged this signal, which means the peripherals
are always on and it is not possible to add peripherals that depend on
the sleep-moci to be on. With this change, we replace the hog with a
regulator so that peripherals can add their own regulators that use the
same gpio. Carrier boards that allow peripherals to be powered off in
suspend can disable this regulator and implement their own regulator to
control the sleep-moci.

This commit adds device tree support for the NXP S32G3-based
S32G-VNP-RDB3 Board [1].
The S32G3 features an 8-core ARM Cortex-A53 based SoC developed by NXP.
The device tree files are derived from the official NXP downstream
Linux tree [2].
This addition encompasses a limited selection of peripherals that
are upstream-supported. Apart from the ARM System Modules
(GIC, Generic Timer, etc.), the following IPs have been validated:
* UART: fsl-linflexuart
* SDHC: fsl-imx-esdhc
Clock settings for the chip rely on ATF Firmware [3].
Pin control integration into the device tree is pending and currently
relies on Firmware/U-Boot settings [4].
These changes were validated using BSP39 Firmware/U-Boot from NXP [5].
The modifications enable booting the official Ubuntu 22.04 from NXP on
the RDB3 with default settings from the SD card and eMMC.

- Undo the deferred 5-level page table setup as it cannot work with

- Prevent inconsistent XFD state on CPU hotplug, where the MSR is reset

result prevents updating the MSR.
- Register the local APIC address only once in the MPPARSE enumeration
to prevent triggering the related WARN_ONs() in the APIC and topology

- Handle the case where no APIC is found gracefully by registering a
fake APIC in the topology code. That makes all related topology
functions work correctly and does not affect the actual APIC driver

- Don't evaluate logical IDs during early boot as the local APIC IDs

- Cure the fallout of the per CPU rework on UP which misplaced the

x86/efistub: Call mixed mode boot services on the firmware's stack
Normally, the EFI stub calls into the EFI boot services using the stack
that was live when the stub was entered. According to the UEFI spec,
this stack needs to be at least 128k in size - this might seem large but
all asynchronous processing and event handling in EFI runs from the same
stack and so quite a lot of space may be used in practice.
In mixed mode, the situation is a bit different: the bootloader calls
the 32-bit EFI stub entry point, which calls the decompressor's 32-bit
entry point, where the boot stack is set up, using a fixed allocation
of 16k. This stack is still in use when the EFI stub is started in
64-bit mode, and so all calls back into the EFI firmware will be using
the decompressor's limited boot stack.
Due to the placement of the boot stack right after the boot heap, any
stack overruns have gone unnoticed. However, commit
5c4feadb0011983b ("x86/decompressor: Move global symbol references to C code")
moved the definition of the boot heap into C code, and now the boot
stack is placed right at the base of BSS, where any overruns will
corrupt the end of the .data section.
While it would be possible to work around this by increasing the size of
the boot stack, doing so would affect all x86 systems, and mixed mode
systems are a tiny (and shrinking) fraction of the x86 installed base.
So instead, record the firmware stack pointer value when entering from
the 32-bit firmware, and switch to this stack every time a EFI boot
service call is made.

x86/boot/64: Move 5-level paging global variable assignments back
Commit
63bed9660420 ("x86/startup_64: Defer assignment of 5-level paging
global variables") moved assignment of 5-level global variables to later
in the boot in order to avoid having to use RIP relative addressing in
order to set them. However, when running with 5-level paging and SME
active (mem_encrypt=on), the variables are needed as part of the page
table setup needed to encrypt the kernel (using pgd_none(), p4d_offset(),
etc.). Since the variables haven't been set, the page table manipulation
is done as if 4-level paging is active, causing the system to crash on
boot.
While only a subset of the assignments that were moved need to be set
early, move all of the assignments back into check_la57_support() so that
these assignments aren't spread between two locations. Instead of just
reverting the fix, this uses the new RIP_REL_REF() macro when assigning
the variables.

x86/fpu: Keep xfd_state in sync with MSR_IA32_XFD
Commit
672365477ae8 ("x86/fpu: Update XFD state where required") and
commit
8bf26758ca96 ("x86/fpu: Add XFD state to fpstate") introduced a
per CPU variable xfd_state to keep the MSR_IA32_XFD value cached, in
order to avoid unnecessary writes to the MSR.
On CPU hotplug MSR_IA32_XFD is reset to the init_fpstate.xfd, which
wipes out any stale state. But the per CPU cached xfd value is not
reset, which brings them out of sync.
As a consequence a subsequent xfd_update_state() might fail to update
the MSR which in turn can result in XRSTOR raising a #NM in kernel
space, which crashes the kernel.
To fix this, introduce xfd_set_state() to write xfd_state together
with MSR_IA32_XFD, and use it in all places that set MSR_IA32_XFD.

race and expires the global queue. This causes the last CPU to

Cure this by re-evaluating the wakeup time unconditionally.
- The split into local (pinned) and global timers in the timer wheel
caused a regression for NOHZ full as it broke the idle tracking of
global timers. On NOHZ full this prevents an self IPI being sent

The boot sequence evaluates CPUID information twice:
1) During early boot
2) When finalizing the early setup right before

In both cases the evaluation is stored in boot_cpu_data, but on UP the
copying of boot_cpu_data to the per CPU info of the boot CPU happens
between #1 and #2. So any update which happens in #2 is never propagated to
the per CPU info instance.
Consolidate the whole logic and copy boot_cpu_data right before applying
alternatives as that's the point where boot_cpu_data is in it's final

More recently the SCSI based UFS (Universal Flash Storage) drivers
have wanted to take advantage of this as well, for the same reasons as
f2fs, necessitating plumbing the write hints through the block layer
and then adding it to the SCSI core.
The vfs write_hints already taken plumbs this as far as block and this
completes the SCSI core enabling based on a recently agreed reuse of
the old write command group number. The additions to the scsi_debug

efi/libstub: fix efi_random_alloc() to allocate memory at alloc_min or higher address
Following warning is sometimes observed while booting my servers:
[ 3.594838] DMA: preallocated 4096 KiB GFP_KERNEL pool for atomic allocations
[ 3.602918] swapper/0: page allocation failure: order:10, mode:0xcc1(GFP_KERNEL|GFP_DMA), nodemask=(null),cpuset=/,mems_allowed=0-1
...
[ 3.851862] DMA: preallocated 1024 KiB GFP_KERNEL|GFP_DMA pool for atomic allocation
If 'nokaslr' boot option is set, the warning always happens.
On x86, ZONE_DMA is small zone at the first 16MB of physical address
space. When this problem happens, most of that space seems to be used by
decompressed kernel. Thereby, there is not enough space at DMA_ZONE to
meet the request of DMA pool allocation.
The commit
2f77465b05b1 ("x86/efistub: Avoid placing the kernel below
LOAD_PHYSICAL_ADDR") tried to fix this problem by introducing lower
bound of allocation.
But the fix is not complete.
efi_random_alloc() allocates pages by following steps.
1. Count total available slots ('total_slots')
2. Select a slot ('target_slot') to allocate randomly
3. Calculate a starting address ('target') to be included target_slot
4. Allocate pages, which starting address is 'target'
In step 1, 'alloc_min' is used to offset the starting address of memory
chunk. But in step 3 'alloc_min' is not considered at all. As the
result, 'target' can be miscalculated and become lower than 'alloc_min'.
When KASLR is disabled, 'target_slot' is always 0 and the problem
happens everytime if the EFI memory map of the system meets the
condition.
Fix this problem by calculating 'target' considering 'alloc_min'.

Which is a false positive.
Reproducer:
- Run rsync of whole kernel tree (multiple times if needed).
- start a kmemleak scan
- Note this is just an example: a lot of our internal tests hit these.
The root cause is similar to the fix in:
b0b592cf0836 x86/pm: Fix false positive kmemleak report in msr_build_context()
ie. the alignment within the packed struct saved_context
which has everything unaligned as there is only "u16 gs;" at start of
struct where in the past there were four u16 there thus aligning
everything afterwards. The issue is with the fact that Kmemleak only
searches for pointers that are aligned (see how pointers are scanned in
kmemleak.c) so when the struct members are not aligned it doesn't see
them.
Testing:
We run a lot of tests with our CI, and after applying this fix we do not
see any kmemleak issues any more whilst without it we see hundreds of
the above report. From a single, simple test run consisting of 416 individual test
cases on kernel 5.10 x86 with kmemleak enabled we got 20 failures due to this,
which is quite a lot. With this fix applied we get zero kmemleak related failures.

x86/kexec: Do not update E820 kexec table for setup_data
crashkernel reservation failed on a Thinkpad t440s laptop recently.
Actually the memblock reservation succeeded, but later insert_resource()
failed.
Test steps:
kexec load -> /* make sure add crashkernel param eg. crashkernel=160M */
kexec reboot ->
dmesg|grep "crashkernel reserved";
crashkernel memory range like below reserved successfully:
0x00000000d0000000 - 0x00000000da000000
But no such "Crash kernel" region in /proc/iomem
The background story:
Currently the E820 code reserves setup_data regions for both the current
kernel and the kexec kernel, and it inserts them into the resources list.
Before the kexec kernel reboots nobody passes the old setup_data, and
kexec only passes fresh SETUP_EFI/SETUP_IMA/SETUP_RNG_SEED if needed.
Thus the old setup data memory is not used at all.
Due to old kernel updates the kexec e820 table as well so kexec kernel
sees them as E820_TYPE_RESERVED_KERN regions, and later the old setup_data
regions are inserted into resources list in the kexec kernel by
e820__reserve_resources().
Note, due to no setup_data is passed in for those old regions they are not
early reserved (by function early_reserve_memory), and the crashkernel
memblock reservation will just treat them as usable memory and it could
reserve the crashkernel region which overlaps with the old setup_data
regions. And just like the bug I noticed here, kdump insert_resource
failed because e820__reserve_resources has added the overlapped chunks
in /proc/iomem already.
Finally, looking at the code, the old setup_data regions are not used
at all as no setup_data is passed in by the kexec boot loader. Although
something like SETUP_PCI etc could be needed, kexec should pass
the info as new setup_data so that kexec kernel can take care of them.
This should be taken care of in other separate patches if needed.
Thus drop the useless buggy code here.
