Marc Zyngier 5e68d2eeac Merge branch kvm-arm64/pkvm-memshare-declutter into kvmarm-master/next ... * kvm-arm64/pkvm-memshare-declutter: : . : pKVM memory transition simplifications, courtesy of Quentin Perret. : : From the cover letter: : "Since its early days, pKVM has formalized memory 'transitions' (shares : and donations) using 'struct pkvm_mem_transition' and bunch of helpers : to manipulate it. The intention was for all transitions to use this : machinery to ensure we're checking things consistently. However, as : development progressed, it became clear that the rigidity of this model : made it really difficult to use in some use-cases which ended-up : side-stepping it entirely. That is the case for the : hyp_{un}pin_shared_mem() and host_{un}share_guest() paths upstream which : use lower level helpers directly, as well as for several other pKVM : features that should land upstream in the future (ex: when a guest : relinquishes a page during ballooning, when annotating a page that is : being DMA'd to, ...). On top of this, the pkvm_mem_transition machinery : requires a lot of boilerplate which makes the code hard to read, but : also adds layers of indirection that no compilers seems to see through, : hence leading to suboptimal generated code. : : Given all the above, this series removes the pkvm_mem_transition : machinery from mem_protect.c, and converts all its users to use : __*_{check,set}_page_state_range() low-level helpers directly." : .
