The following two patches might (hopefully) fix the build breakage on score
and some other architectures. I've checked the new __ex_table checker
still works on x86-64 with them (it still detects an entry pointing to
.altinstr_rplacement) and they should apply cleanly on top of Rusty's
module-next branch.
Thanks to Guenter for the bug analysis and sorry again for the breakage.
Let me know if this makes things better..
Hi Quentin,
the crash is fixed, but now I get
FATAL: The relocation at __ex_table+0x4 references
section "" which is not executable, IOW
the kernel will fault if it ever tries to
jump to it. Something is seriously wrong
and should be fixed.
for parisc:defconfig,
FATAL: The relocation at __ex_table+0x634 references
section "__ex_table" which is not executable, IOW
the kernel will fault if it ever tries to
jump to it. Something is seriously wrong
and should be fixed.
for score:allnoconfig, and
FATAL: The relocation at __ex_table+0x8 references
section "" which is not executable, IOW
it is not possible for the kernel to fault
at that address. Something is seriously wrong
and should be fixed.
for mn10300:defconfig.
While I agree that those should get fixed (if they are real problems,
especially the ones for parisc and mn10300), I don't think it is
a good idea to fail the build because of it.
Note that I did find the problem in the score build; that was a real bug.
I don't know what may be wrong with the others.
Thanks,
Guenter
