FRV: Handle update_mmu_cache() being called when current->mm is NULL [try #2]

2008-04-10T20:41:28+00:00

Handle update_mmu_cache() being called when current->mm is NULL.

We cache static TLB mappings for the current page table in DAMPR4 and DAMPR5
on the theory that the next data lookup is likely to be in the same general
region, and thus is likely to be mapped by the same page table.  However, we
can't get this information if we can't access the appropriate mm_struct.

If current->mm is NULL, we just clear the cache in the knowledge that the TLB
miss handlers will load it.

add mm argument to pte/pmd/pud/pgd_free

2008-02-05T17:44:18+00:00

(with Martin Schwidefsky )

The pgd/pud/pmd/pte page table allocation functions get a mm_struct pointer as
first argument.  The free functions do not get the mm_struct argument.  This
is 1) asymmetrical and 2) to do mm related page table allocations the mm
argument is needed on the free function as well.

move frv docs one level up

2008-02-03T13:54:28+00:00

My first guess for "fujitsu" was it might be related to the
fujitsu-laptop.c driver...

Move the frv directory one level up since frv is the name of the
architecture in the Linux kernel.

mm: remove ptep_test_and_clear_dirty and ptep_clear_flush_dirty

2007-07-17T17:22:59+00:00

Nobody is using ptep_test_and_clear_dirty and ptep_clear_flush_dirty.  Remove
the functions from all architectures.

page table handling cleanup

2007-07-16T16:05:36+00:00

Kill pte_rdprotect(), pte_exprotect(), pte_mkread(), pte_mkexec(), pte_read(),
pte_exec(), and pte_user() except where arch-specific code is making use of
them.

Clean up mostly unused IOSPACE macros

2007-05-08T18:15:13+00:00

Most architectures defined three macros, MK_IOSPACE_PFN(), GET_IOSPACE()
and GET_PFN() in pgtable.h.  However, the only callers of any of these
macros are in Sparc specific code, either in arch/sparc, arch/sparc64 or
drivers/sbus.

This patch removes the redundant macros from all architectures except
sparc and sparc64.

[PATCH] paravirt: remove set pte atomic

2006-10-01T07:39:34+00:00

Now that ptep_establish has a definition in PAE i386 3-level paging code, the
only paging model which is insane enough to have multi-word hardware PTEs
which are not efficient to set atomically, we can remove the ghost of
set_pte_atomic from other architectures which falesly duplicated it, and
remove all knowledge of it from the generic pgtable code.

set_pte_atomic is now a private pte operator which is specific to i386

[PATCH] Standardize pxx_page macros

2006-09-26T15:48:51+00:00

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.
