Alex Elder faa8bf8451 net: ipa: don't assume SMEM is page-aligned ... [ Upstream commit b8d4380365 ] In ipa_smem_init(), a Qualcomm SMEM region is allocated (if needed) and then its virtual address is fetched using qcom_smem_get(). The physical address associated with that region is also fetched. The physical address is adjusted so that it is page-aligned, and an attempt is made to update the size of the region to compensate for any non-zero adjustment. But that adjustment isn't done properly. The physical address is aligned twice, and as a result the size is never actually adjusted. Fix this by *not* aligning the "addr" local variable, and instead making the "phys" local variable be the adjusted "addr" value.
