- Couple of virtual vs physical address confusion fixes - Rework locking in dcssblk driver to address a lockdep warning - Remove support for "noexec" kernel command line option since there is no use case where it would make sense - Simplify kernel mapping setup and get rid of quite a bit of code - Add architecture specific __set_memory_yy() functions which allow to modify kernel mappings. Unlike the set_memory_xx() variants they take void pointer start and end parameters, which allows to use them without the usual casts, and also to use them on areas larger than 8TB. Note that the set_memory_xx() family comes with an int num_pages parameter which overflows with 8TB. This could be addressed by changing the num_pages parameter to unsigned long, however requires to change all architectures, since the module code expects an int parameter (see module_set_memory()). This was indeed an issue since for debug_pagealloc() we call set_memory_4k() on the whole identity mapping. Therefore address this for now with the __set_memory_yy() variant, and address common code later - Use dev_set_name() and also fix memory leak in zcrypt driver error handling - Remove unused lsi_mask from airq_struct - Add warning for invalid kernel mapping requests -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEECMNfWEw3SLnmiLkZIg7DeRspbsIFAmT5sYkACgkQIg7DeRsp bsJQHg//SFJOcVr2uViorvmt+IyiW78H75y8+AC6qoxZ3fuJeuyW2zz/resRsFRO UDCjkV2QYT885ADFUMcunf7LQnJYpSFVjAB6WEhgFr+bFdMWtX1crjHsMHkpcobR Fo4IFurG5NOMIdunPwKiO/dLU8pNGTm1T430uyLZH3ApVrmJ8stgOczusqTO/h3V tjbC5HAm9BBwNyOd2lnZSi8pbUMcfGE2DkRYhFQup1N9NT0BC4S6B8vTsD7NVYVZ WbJzqSl3CnTUJxZFX287YDW6cSaPCLAUfCl7r5FJZUoGvUtOVLlqcOjIIm/72epv YygMI8RdM0KHuzOd8XTNDbBnyYWTmWnZypCQVgNezY1GiO5nfTCkwYLZZagcc0Lo 6fx1B7xBbNao9/pURa6wJ9dXsx+NmD52DjM806hP1H+qoL/YP8dLqV6Qh2C1PFzI VncrnG2mnxjwry5WoOyl19SKqXDgmDylnFuHQHKA9mdCaqZWNkqovOo/6qE6OdWI Q3TinPwTug9vmgwBuQgua/2R1owy7G9mJwwDW9AtZXVzlMG6k06deKIYrZjLxf6Z hOtAu+Xy5IeoXOaaOFU92RsRKX481OTG77rWLREC+orAT1dPrfnguPLlQ7KeFbkR foduTTHcDPOLiIVL1RbWQC9AAw/i7IjN04Jp6KFlQTZqLATyPbM= =+iSZ -----END PGP SIGNATURE----- Merge tag 's390-6.6-2' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux Pull more s390 updates from Heiko Carstens: - A couple of virtual vs physical address confusion fixes - Rework locking in dcssblk driver to address a lockdep warning - Remove support for "noexec" kernel command line option since there is no use case where it would make sense - Simplify kernel mapping setup and get rid of quite a bit of code - Add architecture specific __set_memory_yy() functions which allow us to modify kernel mappings.
