<title>[PATCH] Standardize pxx_page macros</title>

<id>46a82b2d5591335277ed2930611f6acb4ce654ed</id>
<content type='text'>
One of the changes necessary for shared page tables is to standardize the
pxx_page macros.  pte_page and pmd_page have always returned the struct
page associated with their entry, while pte_page_kernel and pmd_page_kernel
have returned the kernel virtual address.  pud_page and pgd_page, on the
other hand, return the kernel virtual address.

Shared page tables needs pud_page and pgd_page to return the actual page
structures.  There are very few actual users of these functions, so it is
simple to standardize their usage.

Since this is basic cleanup, I am submitting these changes as a standalone
patch.  Per Hugh Dickins' comments about it, I am also changing the
pxx_page_kernel macros to pxx_page_vaddr to clarify their meaning.

This adds a vdso_base element to the mm_context_t for 32-bit compiles
(both for ARCH=powerpc and ARCH=ppc).  This fixes the compile errors
that have been reported in arch/powerpc/kernel/signal_32.c.

<title>[PATCH] lock PTE before updating it in 440/BookE page fault handler</title>

Fix 44x and BookE page fault handler to correctly lock PTE before
trying to pte_update() it, otherwise this PTE might be swapped out
after pte_present() check but before pte_uptdate() call, resulting in
corrupted PTE. This can happen with enabled preemption and low memory
condition.

<content type='text'>
The following patch generalizes PPC44x_PIN_SIZE by changing it to
PPC_PIN_SIZE, which can be defined by any sub-arch to automatically adjust
VMALLOC_START.

Define PPC_PIN_SIZE on 8xx, avoiding potential conflicts with the
pinned space.

<title>[PATCH] ppc: make phys_mem_access_prot() work with pfns instead of addresses</title>

<id>8b150478aeb1a8edb9015c2f7ac4da637ff65c45</id>
<content type='text'>
Change the phys_mem_access_prot() function to take a pfn instead of an
address.  This allows mmap64() to work on /dev/mem for addresses above 4G
on 32-bit architectures.  We start with a pfn in mmap_mem(), so there's no
need to convert to an address; in fact, it's actively bad, since the
conversion can overflow when the address is above 4G.

Similarly fix the ppc32 page_is_ram() function to avoid a conversion to an
address by directly comparing to max_pfn.  Working with max_pfn instead of
high_memory fixes page_is_ram() to give the right answer for highmem pages.
