Subject: [PATCH] powerpc/ps3_defconfig: Disable PPC64_BIG_ENDIAN_ELF_ABI_V2
Date: Sun, 24 Dec 2023 09:52:46 +0900 [thread overview]
Message-ID: <df906ac1-5f17-44b9-b0bb-7cd292a0df65@infradead.org> (raw)
Commit 8c5fa3b5c4df3d071dab42b04b971df370d99354 (powerpc/64: Make ELFv2 the
default for big-endian builds), merged in Linux-6.5-rc1 changes the calling ABI
in a way that is incompatible with the current code for the PS3's LV1 hypervisor
calls.
This change just adds the line '# CONFIG_PPC64_BIG_ENDIAN_ELF_ABI_V2 is not set'
to the ps3_defconfig file so that the PPC64_ELF_ABI_V1 is used.
Fixes run time errors like these:
BUG: Kernel NULL pointer dereference at 0x00000000
Faulting instruction address: 0xc000000000047cf0
Oops: Kernel access of bad area, sig: 11 [#1]
Call Trace:
