The prandom_u32() function has been a deprecated inline wrapper around
get_random_u32() for several releases now, and compiles down to the
exact same code. Replace the deprecated wrapper with a direct call to
the real function. The same also applies to get_random_int(), which is
just a wrapper around get_random_u32(). This was done as a basic find
and replace.

Pull MM updates from Andrew Morton:
- Yu Zhao's Multi-Gen LRU patches are here. They've been under test in
linux-next for a couple of months without, to my knowledge, any
negative reports (or any positive ones, come to that).
- Also the Maple Tree from Liam Howlett. An overlapping range-based
tree for vmas. It it apparently slightly more efficient in its own
right, but is mainly targeted at enabling work to reduce mmap_lock
contention.
Liam has identified a number of other tree users in the kernel which
could be beneficially onverted to mapletrees.
Yu Zhao has identified a hard-to-hit but "easy to fix" lockdep splat
at [1]. This has yet to be addressed due to Liam's unfortunately
timed vacation. He is now back and we'll get this fixed up.
- Dmitry Vyukov introduces KMSAN: the Kernel Memory Sanitizer. It uses
clang-generated instrumentation to detect used-unintialized bugs down
to the single bit level.
KMSAN keeps finding bugs. New ones, as well as the legacy ones.
- Yang Shi adds a userspace mechanism (madvise) to induce a collapse of
memory into THPs.
- Zach O'Keefe has expanded Yang Shi's madvise(MADV_COLLAPSE) to
support file/shmem-backed pages.
- userfaultfd updates from Axel Rasmussen
- zsmalloc cleanups from Alexey Romanov
- cleanups from Miaohe Lin: vmscan, hugetlb_cgroup, hugetlb and
memory-failure
- Huang Ying adds enhancements to NUMA balancing memory tiering mode's
page promotion, with a new way of detecting hot pages.
- memcg updates from Shakeel Butt: charging optimizations and reduced
memory consumption.
- memcg cleanups from Kairui Song.
- memcg fixes and cleanups from Johannes Weiner.
- Vishal Moola provides more folio conversions
- Zhang Yi removed ll_rw_block() :(
- migration enhancements from Peter Xu
- migration error-path bugfixes from Huang Ying
- Aneesh Kumar added ability for a device driver to alter the memory
tiering promotion paths. For optimizations by PMEM drivers, DRM
drivers, etc.
- vma merging improvements from Jakub Matěn.
- NUMA hinting cleanups from David Hildenbrand.
- xu xin added aditional userspace visibility into KSM merging
activity.
- THP & KSM code consolidation from Qi Zheng.
- more folio work from Matthew Wilcox.
- KASAN updates from Andrey Konovalov.
- DAMON cleanups from Kaixu Xia.
- DAMON work from SeongJae Park: fixes, cleanups.
- hugetlb sysfs cleanups from Muchun Song.
- Mike Kravetz fixes locking issues in hugetlbfs and in hugetlb core.

Use the VMA iterator instead. This requires a little restructuring of the
surrounding code to hoist the mm to the caller. That turns
cxl_prefault_one() into a trivial function, so call cxl_fault_segment()
directly.

I$ prefetch is enabled when sending a TPC kernel to initialize the TPC
memory, and it has a restriction that the base address will be aligned
to 8KB.
Currently the base address is 128 bytes from the start address of the
device SRAM, so prefetching will start 128 bytes before the actual
kernel memory.
Modify the kernel address to be 8KB aligned.

To be forward-backward compatible with the firmware in the initial
communication during preboot, we need to remove the validation of the
header size. This will allow us to add more fields to the
lkd_fw_comms_desc structure.
Instead of the validation of the header size, we just print warning
when some mismatch in descriptor has been revealed, and we calculate
the CRC base on descriptor size reported by the firmware instead of
calculating it ourselves.

The access to the device registers is blocked during hard reset, until
preboot runs and allows the access to specific registers, including the
PSOC BTM_FSM register which is used to know when the reset is done.
Between the reset request and until this register is polled there is a
small delay of 500 msec which is not enough for F/W to process the reset
and for preboot to run, so the register might be accessed while it is
blocked.
To avoid it, increase the delay to 2 sec.

The code used the mmu mutex to protect access to the context's page
tables and invalidation of the MMU cache. Because pgt are per
context, the mmu mutex was a member of the context object.
The problem is that the device has a single MMU invalidation h/w
(per MMU). Therefore, the mmu mutex should not be a property of the
context but a property of the device.

Current code does not takes into account the new DRAM region base
and so calculated address is wrong and can lead to crush.

F/W security status might change after every reset.
Add the reading of the preboot status to the hard reset sequence, which
among others reads this security indication.
As this preboot status reading includes the waiting for the preboot to
be ready, it can be removed from the CPU init which is done in a later
stage.

cb_map_mem() uses gen_pool_alloc() to get virtual address for
mapping a CB.
The mapping is done in chunks of page size, so if the CB size is
larger, it is possible that the allocated virtual addresses won't
be consecutive.
User retrieves this device VA which returns the virtual address
in the first va_block. If there is a "hole" in the virtual addresses,
user can configure a HW block with a bad device VA.

This patch add tracepoints in the code for DMA allocation.
The main purpose is to be able to cross data with the map operations and
determine whether memory violation occurred, for example free DMA
allocation before unmapping it from device memory.
To achieve this the DMA alloc/free code flows were refactored so that a
single DMA tracepoint will catch many flows.
To get better understanding of what happened in the DMA allocations
the real allocating function is added to the trace as well.

This patch adds trace events for habanalabs driver to gain all the
benefits such an infrastructure can supply.
The following events were added:
- MMU map/unmap: to be able to track driver's memory allocations
- DMA alloc/free: to track our DMA allocation
the above trace points in conjunction will help us map the device memory
usage as well as to be able to track memory violations.

The calculation of the device DRAM base address before setting the
relevant PCIe BAR to point at it, has an assumption that this BAR is
used to access only the DRAM, and thus the covered DRAM size is a power
of 2.
In future ASICs it is not necessarily true, so need to update the
calculation to support also a non-power-of-2 size.
