I meant this: https://lkml.kernel.org/r/20160902181447.GA25328@xxxxxxxxxxx Wouldn't simply clearing the SME mask work? #define __va(x) ((void *)(((unsigned long)(x)+PAGE_OFFSET) & ~sme_me_mask)) Or are you saying, one needs the whole noodling through ioremap_cache() because the data is already encrypted and accessing it with sme_me_mask cleared would simply give you the encrypted garbage? -- Regards/Gruss, Boris.
