Source: linux Version: 4.7.2-1 Severity: normal User: debian-powerpc@lists.debian.org Usertags: powerpcspe Hi! Linux 4.7.x introduced another regression on powerpcspe due to the use of unsupported assembly instructions [1]: /<<PKGBUILDDIR>>/arch/powerpc/xmon/spr_access.S: Assembler messages: /<<PKGBUILDDIR>>/arch/powerpc/xmon/spr_access.S:5: Error: unrecognized opcode: `ld' /<<PKGBUILDDIR>>/arch/powerpc/xmon/spr_access.S:10: Error: unrecognized opcode: `ld' /<<PKGBUILDDIR>>/scripts/Makefile.build:331: recipe for target 'arch/powerpc/xmon/spr_access.o' failed make[6]: *** [arch/powerpc/xmon/spr_access.o] Error 1 This is very reminiscent of #823526 [2] which also used some FPU instructions not available on powerpcspe/e500. And, indeed, like "ldarx" and "stdcx", "ld" is not available on e500 either [3] (see p. 3-68). I haven't looked at the code yet, but I assume guarding the code with some additional #ifdef's should fix the issue the same way as in #823526.

Please don't add the pending tag just because a patch has been accepted upstream. Anyway, I have applied this to the sid branch so it really is pending now.
