s390/vmem: do not silently ignore mapping limit (2023-09-05 20:12:52 +0200)
----------------------------------------------------------------
more s390 updates for 6.6 merge window
- 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
