It certainly looks like the issue, looking at the numbers again:
Sections:
Idx Name Size VMA LMA File off Algn
0 .text 0023bf43 f0000020 f0000020 00008020 2**5
CONTENTS, ALLOC, LOAD, READONLY, CODE
1 link_set_malloc_types 00000120 f023bf64 f023bf64 00243f64 2**2
CONTENTS, ALLOC, LOAD, READONLY, DATA
2 link_set_sysctl_funcs 0000008c f023c084 f023c084 00244084 2**2
CONTENTS, ALLOC, LOAD, READONLY, DATA
3 link_set_evcnts 00000004 f023c110 f023c110 00244110 2**2
CONTENTS, ALLOC, LOAD, READONLY, DATA
4 .data 000462c0 f023d000 f023d000 00245000 2**2
CONTENTS, ALLOC, LOAD, DATA
The maths currently works out that it's actually:
f0000020 + 0023bf43 = f0023bf63
Rounding up to the nearest page makes it f0023c000.
However, the cats kern.ldscript isn't using SIZEOF. perhaps the issue
is that it doesn't list the link_set* sections in it's .text section?
