MIPS: vmlinux: discard .MIPS.abiflags
Discard .MIPS.abiflags from vmlinux. It's not needed and will cause
issues e.g. with old OCTEON bootloaders that cannot tolerate
additional program headers.
Before the patch:
$ readelf --program-headers octeon-vmlinux
Elf file type is EXEC (Executable file)
Entry point 0xffffffff815d09d0
There are 3 program headers, starting at offset 64
Program Headers:
Type Offset VirtAddr PhysAddr
FileSiz MemSiz Flags Align
ABIFLAGS 0x00000000005e77f0 0xffffffff816e67f0 0xffffffff816e67f0
0x0000000000000018 0x0000000000000018 R 8
LOAD 0x0000000000001000 0xffffffff81100000 0xffffffff81100000
0x0000000000b57f80 0x0000000001b86360 RWE 1000
NOTE 0x00000000004e02e0 0xffffffff815df2e0 0xffffffff815df2e0
0x0000000000000024 0x0000000000000024 R 4
After the patch:
$ readelf --program-headers octeon-vmlinux
Elf file type is EXEC (Executable file)
Entry point 0xffffffff815d09d0
There are 2 program headers, starting at offset 64
Program Headers:
Type Offset VirtAddr PhysAddr

LOAD 0x0000000000001000 0xffffffff81100000 0xffffffff81100000
