Merge tag 'memblock-v6.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rppt/memblock
Pull memblock update from Mike Rapoport:
"Report failures when memblock_can_resize is not set.
Numerous memblock reservations at early boot may exhaust static
memblock.reserved array and it is unnoticed because most of the
callers don't check memblock_reserve() return value.
In this case the system will crash later, but the reason is hard to
identify.
Replace return of an error with panic() when memblock.reserved is
exhausted before it can be resized"
