Hello Vivek,
commit 8fc5b4d introduces a regression that no longer allows to compile
x86_64 kernel under x86_32 userland. TJ on freenode/#kernel did analyze
it:
> (mini) [~/work/linux-2.6] make
> scripts/kconfig/conf --silentoldconfig Kconfig
> CHK include/config/kernel.release
> UPD include/config/kernel.release
> CHK include/generated/uapi/linux/version.h
> CHK include/generated/utsrelease.h
> UPD include/generated/utsrelease.h
> CC arch/x86/purgatory/purgatory.o
> arch/x86/purgatory/purgatory.c:1:0: error: code model 'large' not supported
> in the 32 bit mode
> make[1]: *** [arch/x86/purgatory/purgatory.o] Error 1
> make: *** [archprepare] Error 2
08:10 < TJ-> Glanzmann: The purgatory code from kexec is specifying ".code64"
08:11 < TJ-> Glanzmann: so when your local 32-bit linker tries to deal with
that ... it errors
08:14 < TJ-> Glanzmann: there's only one introducing the purgatory stuff
08:14 < TJ-> 8fc5b4d Fri Aug 8 15:57:32 2014 -0700 Vivek Goyal purgatory: core
purgatory functionality
Cheers,
Thomas
