--- Comment #24 from Christophe Leroy (christophe.le...@csgroup.eu) ---
Seems like with Inline KASAN your kernel is far too big compared to what we
support at the time being:
c2468000 T __end_rodata
c2800000 T __init_begin
c2800000 T _sinittext
c2801644 T prom_init
The init text section is behind the 32Mbytes boundary, it means that prom_init
and other functions are not called anymore directly but via a trampoline.
c000000c <__start>:
c000000c: 2c 05 00 00 cmpwi r5,0
c0000010: 41 82 00 1c beq c000002c <__start+0x20>
c0000014: 42 9f 00 05 bcl 20,4*cr7+so,c0000018 <__start+0xc>
c0000018: 7d 08 02 a6 mflr r8
c000001c: 3d 08 00 00 addis r8,r8,0
c0000020: 39 08 ff e8 addi r8,r8,-24
c0000024: 48 00 38 e5 bl c0003908 <setup_disp_bat+0x30>
...
c0003908: 3d 80 c2 80 lis r12,-15744
c000390c: 39 8c 16 44 addi r12,r12,5700
c0003910: 7d 89 03 a6 mtctr r12
c0003914: 4e 80 04 20 bctr
And it cannot work because at that time the kernel is not yet relocated to its
final location.
There was the same problem with PPC64 and it was fix by 24d33ac5b8ff
("powerpc/64s: Make prom_init require RELOCATABLE").
Don't know if a similar approach could work.
