If anyone has any objections, please let me know. ------------------ From: Geoff Levand commit 482b718a84f08b6fc84879c3e90cc57dba11c115 upstream. Commit 8c5fa3b5c4df ("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: [c0000000023039e0] [c00000000100ebfc] ps3_create_spu+0xc4/0x2b0 (unreliable) [c000000002303ab0] [c00000000100d4c4] create_spu+0xcc/0x3c4 [c000000002303b40] [c00000000100eae4] ps3_enumerate_spus+0xa4/0xf8 Fixes: 8c5fa3b5c4df ("powerpc/64: Make ELFv2 the default for big-endian builds") Cc: stable@vger.kernel.org # v6.5+ Signed-off-by: Geoff Levand Signed-off-by: Michael Ellerman Link: https://msgid.link/df906ac1-5f17-44b9-b0bb-7cd292a0df65@infradead.org Signed-off-by: Greg Kroah-Hartman --- arch/powerpc/configs/ps3_defconfig | 1 + 1 file changed, 1 insertion(+) diff --git a/arch/powerpc/configs/ps3_defconfig b/arch/powerpc/configs/ps3_defconfig index 2b175ddf82f0..aa8bb0208bcc 100644 --- a/arch/powerpc/configs/ps3_defconfig +++ b/arch/powerpc/configs/ps3_defconfig @@ -24,6 +24,7 @@ CONFIG_PS3_VRAM=m CONFIG_PS3_LPM=m # CONFIG_PPC_OF_BOOT_TRAMPOLINE is not set CONFIG_KEXEC=y +# CONFIG_PPC64_BIG_ENDIAN_ELF_ABI_V2 is not set CONFIG_PPC_4K_PAGES=y CONFIG_SCHED_SMT=y CONFIG_PM=y -- 2.43.0
