[PATCH 0/2] x86/mm: Make memremap(MEMREMAP_WB) map memory as encrypted by default

[Kirill A. Shutemov]

Make memremap(MEMREMAP_WB) produce encrypted/private mapping by default
unless MEMREMAP_DEC is specified.

It fixes crash on kexec in TDX guests if CONFIG_EISA is enabled.

Kirill A. Shutemov (2):
  memremap: Pass down MEMREMAP_* flags to arch_memremap_wb()
  x86/mm: Make memremap(MEMREMAP_WB) map memory as encrypted by default
