Sure.

I have a question regarding the patch. I saw that the structure start at
the end of the relocation code:

data = reboot_code_buffer + relocate_new_kernel_size;

which means it overlap with the global symbol relocate_new_kernel_size.
I think is minor comment as the variable is only used in the fncpy()
then thrown away. Something like:

data = reboot_code_buffer + relocate_new_kernel_size + sizeof(long);

and accordingly in the instruction (arch/arm/kernel/relocate_kernel.S):

adr	r7, relocate_new_kernel_end
