Should be:

.if NR_IRQS gt 16 # only build this for IO-APIC
.align 8,0x90 # make ENTRY have exact address
irq_align=8 # start with 8-byte alignment
ENTRY(high_irq_entries_start)
.rept NR_IRQS-16 # the rest of the stubs
.align irq_align,0x90
1: pushl $vector-256 # 5-byte instruction
jmp common_interrupt # 2 or 5 bytes (8 or 32-bit offset)
2:
.if 2b-1b > 8 # offset changed to 32-bit
irq_align=16 # switch to 16-byte alignment
.endif
.data
.long 1b
.text
vector=vector+1
.endr
.endif
