-Loading a large (~2.1G) files with kexec crashes the host with when
-running:
-
-  # kexec --load kernel --initrd initrd_with_2G_or_more
-
-  UBSAN: signed-integer-overflow in ./include/crypto/sha256_base.h:64:19
-  34152083 * 64 cannot be represented in type 'int'
-  ...
-  BUG: unable to handle page fault for address: ff9fffff83b624c0
-  sha256_update (lib/crypto/sha256.c:137)
-  crypto_sha256_update (crypto/sha256_generic.c:40)
-  kexec_calculate_store_digests (kernel/kexec_file.c:769)

-(Line numbers based on commit da274362a7bd9 ("Linux 6.12.49")
-
-This started happening after commit f4da7afe07523f
-("kexec_file: increase maximum file size to 4G") that landed in v6.0,
-which increased the file size for kexec.
-
-This is not happening upstream (v6.16+), given that `block` type was
-upgraded from "int" to "size_t" in commit 74a43a2cf5e8 ("crypto:
-lib/sha256 - Move partial block handling out")
-
-Upgrade the block type similar to the commit above, avoiding hitting the
-overflow.
-
-This patch is only suitable for the stable tree, and before 6.16, which
-got commit 74a43a2cf5e8 ("crypto: lib/sha256 - Move partial block
-handling out"). This is not required before f4da7afe07523f ("kexec_file:
-increase maximum file size to 4G"). In other words, this fix is required
-between versions v6.0 and v6.16.
