This seems to break sparc64_defconfig when applied on top of v6.5-rc1:
In file included from /home/broonie/git/bisect/include/linux/mm.h:29, from /home/broonie/git/bisect/net/core/skbuff.c:40: /home/broonie/git/bisect/include/linux/pgtable.h: In function 'pmd_mkwrite': /home/broonie/git/bisect/include/linux/pgtable.h:528:9: error: implicit declaration of function 'pmd_mkwrite_novma'; did you mean 'pte_mkwrite_novma'? [-Werror=implicit-function-declaration] return pmd_mkwrite_novma(pmd); ^~~~~~~~~~~~~~~~~ pte_mkwrite_novma /home/broonie/git/bisect/include/linux/pgtable.h:528:9: error: incompatible types when returning type 'int' but 'pmd_t' {aka 'struct <anonymous>'} was expected return pmd_mkwrite_novma(pmd); ^~~~~~~~~~~~~~~~~~~~~~
The same issue seems to apply with the version that was in -next based on v6.4-rc4 too. [unhandled content-type:application/pgp-signature] | |
