mm/vmalloc: Add empty <asm/vmalloc.h> headers and use them from <linux/vmalloc.h> In the x86 MM code we'd like to untangle various types of historic header dependency spaghetti, but for this we'd need to pass to the generic vmalloc code various vmalloc related defines that customarily come via the <asm/page.h> low level arch header.

mm, x86/mm: Untangle address space layout definitions from basic pgtable type definitions - Untangle the somewhat incestous way of how VMALLOC_START is used all across the kernel, but is, on x86, defined deep inside one of the lowest level page table headers. It doesn't help that vmalloc.h only includes a single asm header: #include <asm/page.h> /* pgprot_t */ So there was no existing cross-arch way to decouple address layout definitions from page.h details. I used this: #ifndef VMALLOC_START # include <asm/vmalloc.h> #endif This way every architecture that wants to simplify page.h can do so. - Also on x86 we had a couple of LDT related inline functions that used the late-stage address space layout positions - but these could be uninlined without real trouble - the end result is cleaner this way as well.
