[MIPS] Fix mprotect() syscall for MIPS32 w/36-bit physical address support

Fix mprotect() syscall for MIPS32 CPUs with 36-bit physical address
support: pte_modify() macro didn't clear the hardware page protection bits
before modifying...

[SPARC64]: Fix D-cache corruption in mremap

2006-06-02T00:47:25+00:00

If we move a mapping from one virtual address to another,
and this changes the virtual color of the mapping to those
pages, we can see corrupt data due to D-cache aliasing.

Check for and deal with this by overriding the move_pte()
macro.  Set things up so that other platforms can cleanly
override the move_pte() macro too.

[MIPS] Fix marking buddy of pte global for MIPS32 w/36-bit physical address

2006-05-31T23:28:30+00:00

    
In case of CONFIG_64BIT_PHYS_ADDR, set_pte() and pte_clear() functions
only set _PAGE_GLOBAL bit in the pte_low field of the buddy PTEs,
forgetting to propagate ito to pte_high. Thus, the both pages might not
really be made global for the CPU (since it AND's the G-bit of the
odd / even PTEs together to decide whether they're global or not). Thus,
if only a single page is allocated via vmalloc() or ioremap(), it's not
really global for CPU (and it must be, since this is kernel mapping),
and thus its ASID is compared against the current process' one -- so,
we'll get into trouble sooner or later...  Also, pte_none() will fail
on global pages because _PAGE_GLOBAL bit is set in both pte_low and
pte_high, and pte_val() will return u64 value consisting of those fields
concateneted.

[PATCH] fix remaining missing includes

2005-11-07T15:53:41+00:00

Fix more include file problems that surfaced since I submitted the previous
fix-missing-includes.patch.  This should now allow not to include sched.h
from module.h, which is done by a followup patch.

[PATCH] vm: remove unused/broken page_pte[_prot] macros

2005-10-31T01:37:22+00:00

This patch removes page_pte_prot and page_pte macros from all
architectures.  Some architectures define both, some only page_pte (broken)
and others none.  These macros are not used anywhere.

page_pte_prot(page, prot) is identical to mk_pte(page, prot) and
page_pte(page) is identical to page_pte_prot(page, __pgprot(0)).

* The following architectures define both page_pte_prot and page_pte

  arm, arm26, ia64, sh64, sparc, sparc64

* The following architectures define only page_pte (broken)

  frv, i386, m32r, mips, sh, x86-64

* All other architectures define neither
