Description
In the Linux kernel, the following vulnerability has been resolved: powerpc/ps3_defconfig: Disable PPC64_BIG_ENDIAN_ELF_ABI_V2 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
