If you fix the issue, kindly add following tag as appropriate
Reported-by: kernel test robot <redacted>


"sparse warnings: (new ones prefixed by >>)"

arch/arm64/kernel/hibernate.c:181:39: sparse: sparse: cast to restricted gfp_t
arch/arm64/kernel/hibernate.c:202:44: sparse: sparse: cast from restricted gfp_t

__force attribute is needed in order to fix these warnings from
sparse. Do you want me to send you an updated version of

"arm64: trans_pgd: make trans_pgd_map_page generic" ?

Please send patches on top of for-next/kexec, as I've already queued the
patch above.

That said, why not change 'struct trans_pgd_info' to use the correct types,
instead of 'void *'?

Will
