9364a7e40d memblock tests: fix implicit declaration of function 'numa_valid_node'
commit 8043832e2a ("memblock: use numa_valid_node() helper to check
for invalid node ID") introduce a new helper numa_valid_node(), which is
not defined in memblock tests.

Let's add it in the corresponding header file.

94ff46de4a memblock: Move late alloc warning down to phys alloc
If a driver/subsystem tries to do an allocation after the memblock
allocations have been freed and the memory handed to the buddy
allocator, it will not actually be legal to use that allocation: the
buddy allocator owns the memory. Currently this mis-use is handled by
the memblock function which does allocations and returns virtual
addresses by printing a warning and doing a kmalloc instead. However
the physical allocation function does not to do this check - callers of
the physical alloc function are unprotected against mis-use.

Improve the error catching here by moving the check into the physical
allocation function which is used by the virtual addr allocation
function.

d9d814eebb pstore/ramoops: Add ramoops.mem_name= command line option
Add a method to find a region specified by reserve_mem=nn:align:name for
ramoops. Adding a kernel command line parameter:

  reserve_mem=12M:4096:oops ramoops.mem_name=oops

Will use the size and location defined by the memmap parameter where it
finds the memory and labels it "oops". The "oops" in the ramoops option
is used to search for it.

This allows for arbitrary RAM to be used for ramoops if it is known that
the memory is not cleared on kernel crashes or soft reboots.

1e4c64b71c mm/memblock: Add "reserve_mem" to reserved named memory at boot up
In order to allow for requesting a memory region that can be used for
things like pstore on multiple machines where the memory layout is not the
same, add a new option to the kernel command line called "reserve_mem".

The format is:  reserve_mem=nn:align:name

Where it will find nn amount of memory at the given alignment of align.
The name field is to allow another subsystem to retrieve where the memory
was found. For example:

  reserve_mem=12M:4096:oops ramoops.mem_name=oops

Where ramoops.mem_name will tell ramoops that memory was reserved for it
via the reserve_mem option and it can find it by calling:

  if (reserve_mem_find_by_name("oops", &start, &size)) {
	// start holds the start address and size holds the size given

This is typically used for systems that do not wipe the RAM, and this
command line will try to reserve the same physical memory on soft reboots.
Note, it is not guaranteed to be the same location. For example, if KASLR
places the kernel at the location of where the RAM reservation was from a
previous boot, the new reservation will be at a different location.  Any
subsystem using this feature must add a way to verify that the contents of
the physical memory is from a previous boot, as there may be cases where
the memory will not be located at the same location.

Not all systems may work either. There could be bit flips if the reboot
goes through the BIOS. Using kexec to reboot the machine is likely to
have better results in such cases.

0e9899feed mm/mm_init.c: don't initialize page->lru again
Current page initialization call flow looks like this with some
simplification:

setup_arch()
  paging_init()
    free_area_init()
      memmap_init()
        memmap_init_zone_range()
	  memmap_init_range()
	    defer_init()
	    __init_single_page()
mm_core_init()
  mem_init()
    memblock_free_all()
      free_low_memory_core_early()
        memmap_init_reserved_pages()
          reserve_bootmem_region()
	    init_reserved_page()
	      __init_single_page()

There two cases depends on CONFIG_DEFERRED_STRUCT_PAGE_INIT.

  * If CONFIG_DEFERRED_STRUCT_PAGE_INIT, pages after first_init_pfn is
    skipped at defer_init(). Then init_reserved_page() is defined to
    call __init_single_page() for them.
  * If !CONFIG_DEFERRED_STRUCT_PAGE_INIT, pages are all initialized by
    memmap_init_range().

In both cases, after init_reserved_page(), we expect __init_single_page()
has done its work to the page, which already initialize page->lru properly.

We don't need to do it again.

f1180fd2a7 mm/mm_init.c: not always search next deferred_init_pfn from very beginning
In function deferred_init_memmap(), we call
deferred_init_mem_pfn_range_in_zone() to get the next deferred_init_pfn.
But we always search it from the very beginning.

Since we save the index in i, we can leverage this to search from i next
time.

721f4a6526 mm/memblock: remove empty dummy entry
The dummy entry is introduced in the initial implementation of lmb in
commit 7c8c6b9776 ("powerpc: Merge lmb.c and make MM initialization
use it.").

As the comment says the empty dummy entry is to simplify the code.

	/* Create a dummy zero size LMB which will get coalesced away later.
         * This simplifies the lmb_add() code below...
         */

While current code is reimplemented by Tejun in commit 784656f9c6
("memblock: Reimplement memblock_add_region()"). This empty dummy entry
seems not benefit the code any more.

Let's remove it.

f26ee67a0f TTY fix for 6.10-rc2
Here is a single revert for a much-reported regression in 6.10-rc1 when
 it comes to a few older architectures.  Turns out that the VT ioctls
 don't work the same across all cpu types because of some old
 compatibility requrements for stuff like alpha and powerpc.  So revert
 the change that attempted to have them use the _IO() macros and go back
 to the known-working values instead.
 
 This has NOT been in linux-next but has had many reports that it fixes
 the issue with 6.10-rc1.

d5931dd0de spi: Fixes for v6.10
A series of fixes that came in since the merge window, the main thing
 being the fixes Andy did for DMA sync where we were calling into the DMA
 API in suprising ways and causing issues as a result, the main thing
 being confusing the IOMMU code.
 
 We've also got some fairly important fixes for the stm32 driver, it
 supports a wide range of hardware and some optimisations that were done
 recently have broken on some systems, and a fix to prevent glitched
 signals on the bus in the cadence driver.

   on XIP systems with huge pages.
 * An update to the uABI documentation clarifying that only scalar

0c2f6d0461 x86/topology/intel: Unlock CPUID before evaluating anything
Intel CPUs have a MSR bit to limit CPUID enumeration to leaf two. If
this bit is set by the BIOS then CPUID evaluation including topology
enumeration does not work correctly as the evaluation code does not try
to analyze any leaf greater than two.

This went unnoticed before because the original topology code just
repeated evaluation several times and managed to overwrite the initial
limited information with the correct one later. The new evaluation code
does it once and therefore ends up with the limited and wrong
information.

Cure this by unlocking CPUID right before evaluating anything which
depends on the maximum CPUID leaf being greater than two instead of
rereading stuff after unlock.

d551ce15d0 mailbox: zynqmp-ipi: drop irq_to_desc() call
irq_to_desc() is not exported to loadable modules, so this driver now
fails to link in some configurations:

ERROR: modpost: "irq_to_desc" [drivers/mailbox/zynqmp-ipi-mailbox.ko] undefined!

I can't see a purpose for this call, since the return value is unused
and probably left over from some code refactoring.

Address the link failure by just removing the line.

adb77bba9c scsi: mpt3sas: Avoid possible run-time warning with long manufacturer strings
The prior strscpy() replacement of strncpy() here expected the
manufacture_reply strings to be NUL-terminated, but it is possible
they are not, as the code pattern here shows, e.g., edev->vendor_id
being exactly 1 character larger than manufacture_reply->vendor_id,
and the replaced strncpy() was copying only up to the size of the
source character array. Replace this with memtostr(), which is the
unambiguous way to convert a maybe not-NUL-terminated character array
into a NUL-terminated string.
