Supply signed division to fix ARM compilation.
...
Previously we supplied only unsigned divisions on platforms that need software
division.
Yet compiler may itself use a signed division. A typical example would be a
difference between 2 pointers which involves division by object size.

grub-core/kern/arm/misc.S: fix unaligned grub_uint64_t local variable
...
The unaligned local in __aeabi_uidivmod leads to a store to a 64bit
value at an address that is not divisible by 8 (in grub_divmod64).
The compiler most likely generates a STRD instruction to store it and
this causes an exception.

efi: check *path non-null before grub_strrchr
...
The EFI version of grub_machine_get_bootlocation crops the boot image
name back to the last / in order to get a directory path. However, it
does not check that *name is actually set before calling grub_strrchr
to do this, and neither does grub_strrchr before dereferencing a NULL
pointer.
Parent function, grub_set_prefix_and_root, does check the pointer
before using.

A bit tricky because this function has to continue to work without
