Jakub's patch seems to work (though I cannot *verify* the kernel
images on real hardware), so that will presumably fix these
configations (from the ICE point of view):
linux-powerpc-adder875_defconfig
linux-powerpc-akebono_defconfig
linux-powerpc-lite5200b_defconfig
linux-powerpc-mgcoge_defconfig
linux-powerpc-motionpro_defconfig
linux-powerpc-mpc5200_defconfig
linux-powerpc-mpc8272_ads_defconfig
linux-powerpc-ppc6xx_defconfig
linux-powerpc-tqm5200_defconfig
linux-powerpc-tqm8xx_defconfig
linux-powerpc-warp_defconfig
linux-powerpc-pq2fads_defconfig
linux-powerpc-ps3_defconfig
linux-powerpc-mpc885_ads_defconfig
linux-powerpc-ep8248e_defconfig
linux-powerpc-ep88xc_defconfig
linux-powerpc-iss476-smp_defconfig
linux-powerpc-fsp2_defconfig
linux-powerpc-currituck_defconfig
So we have these remaining build issues:
linux-powerpc-cell_defconfig bad asm
(arch/powerpc/boot/pseries-head.S)
linux-powerpc-mvme5100_defconfig bad asm
(arch/powerpc/kernel/epapr_hcalls.S)
linux-powerpc-asp8347_defconfig bad asm (arch/powerpc/kernel/pmc.c)
linux-powerpc-ppc6xx_defconfig bad asm (arch/powerpc/kernel/pmc.c)
linux-powerpc-ppc64e_defconfig bad asm
(arch/powerpc/kernel/vdso/gettimeofday.S)
linux-powerpc-corenet64_smp_defconfig bad asm
(arch/powerpc/kernel/vdso/gettimeofday.S)
I do *not* have CROSS32_COMPILE=... set for my builds. Maybe that
could cure at least the issues within the ./boot and ./kernel/vdso
directories? Let's try that... But I guess that won't help for the
other two remaining files (arch/powerpc/kernel/{epapr_hcalls.S,pmc.c).
linux-powerpc-pseries_defconfig sstep (out of array bounds)
linux-powerpc-powernv_defconfig sstep
linux-powerpc-ppc64_defconfig sstep
linux-powerpc-pseries_le_defconfig sstep
linux-powerpc-ppc64le_defconfig sstep
linux-powerpc-ppc64le_guest_defconfig sstep
linux-powerpc-ppc64_guest_defconfig sstep
linux-powerpc-powernv_be_defconfig sstep
My first guess on these is that it's a wrong warning. The union's
`u8 b[2 * sizeof(double)]` seems to be large enough.
linux-powerpc-akebono_defconfig ahci (BUILD_BUG_ON failed: sizeof(_s) >
sizeof(long))
linux-powerpc-xes_mpc85xx_defconfig ahci
linux-powerpc-ge_imp3a_defconfig ahci
linux-powerpc-mpc85xx_defconfig ahci
linux-powerpc-mpc85xx_smp_defconfig ahci
linux-powerpc-corenet32_smp_defconfig ahci
linux-powerpc-mpc86xx_defconfig ahci
linux-powerpc-mpc86xx_smp_defconfig ahci
I've seen the AHCI issue on other (non-powerpc) builds as well,
haven't looked into this so I won't guess about whether this is a real
bug or a compiler issue.
Thanks,
Jan-Benedict
