[ Upstream commit 2cbade17b18c0f0fd9963f26c9fc9b057eb1cb3a ]
The __switch_mm function is defined in the user code, and is called
by the kernel code. It should be declared in a shared header.
Fixes: 4dc706c2f2 ("um: take um_mmu.h to asm/mmu.h, clean asm/mmu_context.h a bit")

it's x86-only and we have no business playing with it in asm/mmu.h; make
the latter have
struct uml_arch_mm_context arch;
instead of
struct uml_ldt ldt;
and let arch/<subarch>/um/asm/mm_context.h decide what'll be in there.
While we are at it, kill host_ldt.h - it's not needed in part of places
that include it (we want asm/ldt.h in those) and it can be trivially
expanded into the single remaining one.
