[patch 0/7] x86, cpa: cpa related changes to be inline with TLB Application note

[Suresh Siddha]

TLB Application note[1] says:
	
"The TLBs may contain both ordinary and large-page translations for a 4-KByte
 range of linear addresses. This may occur if software modifies the paging
 structures so that the page size used for the address range changes. If the
 two translations differ with respect to page frame or attributes (e.g.,
 permissions), processor behavior is undefined and may be implementation 
 specific. The processor may use a page frame or attributes that correspond to
 neither translation; it may improperly set or fail to set the dirty bit in the
 appropriate paging-structure entry.
 
 Such undefined behavior is problematic because prefetches and memory accesses
 that are a result of speculative execution may occur, using the affected range
 of linear addresses. It is also problematic if software (including the software
 modifying the paging structures) is accessing data or executing code in the
 affected range of linear addresses. Software should not write to a
 paging-structure entry in a way that would change, for any linear address,
 both the page size and either the page frame or attributes."

Currently we violate this at:

a. kernel identity mapping, where large/small pages setup very early in the
   boot will be split up/merged into large pages along with attribute changes
   during the direct memory mapping init.

b. while doing cpa(), potentially we will split large page and change attribute
   both at the same time.

Following patches fixes this behavior.

[patch 2/7] x86, cpa: remove USER permission from the very early identity mapping attribute

[Suresh Siddha]

[-- Attachment #1: change_init_pte_mapping.patch --]
[-- Type: text/plain, Size: 1050 bytes --]

remove USER from the PTE/PDE attributes for the very early identity
mapping. We overwrite these mappings with KERNEL attribute later
in the boot. Just being paranoid here as there is no need for USER bit
to be set.

If this breaks something(don't know the history), then we can simply drop
this change.

[patch 3/7] x86, cpa: make the kernel physical mapping initialization a two pass sequence

[Suresh Siddha]

[-- Attachment #1: fix_large_small_page_identity_mappings.patch --]
[-- Type: text/plain, Size: 8944 bytes --]

In the first pass, kernel physical mapping will be setup using large or
small pages but uses the same PTE attributes as that of the early
PTE attributes setup by early boot code in head_[32|64].S

After flushing TLB's, we go through the second pass, which setups the
direct mapped PTE's with the appropriate attributes (like NX, GLOBAL etc)
which are runtime detectable.

This two pass mechanism conforms to the TLB app note which says:

"Software should not write to a paging-structure entry in a way that would
 change, for any linear address, both the page size and either the page frame
 or attributes."

[patch 4/7] x86, cpa: dont use large pages for kernel identity mapping with DEBUG_PAGEALLOC

[Suresh Siddha]

[-- Attachment #1: no_lp_identity_mapping_debug_pgalloc.patch --]
[-- Type: text/plain, Size: 4109 bytes --]

Don't use large pages for kernel identity mapping with DEBUG_PAGEALLOC.
This will remove the need to split the large page for the
allocated kernel page in the interrupt context.

This will simplify cpa code(as we don't do the split any more from the
interrupt context). cpa code simplication in the subsequent patches.

[patch 7/7] x86, cpa: global flush tlb after splitting large page and before doing cpa

[Suresh Siddha]

[-- Attachment #1: global_flush_tlb.patch --]
[-- Type: text/plain, Size: 2509 bytes --]

Do a global flush tlb after splitting the large page and before we do the
actual change page attribute in the PTE.

With out this, we violate the TLB application note, which says
    "The TLBs may contain both ordinary and large-page translations for
     a 4-KByte range of linear addresses. This may occur if software
     modifies the paging structures so that the page size used for the
     address range changes. If the two translations differ with respect
     to page frame or attributes (e.g., permissions), processor behavior
     is undefined and may be implementation-specific."

hm, -tip testing found sporadic lockups on a testbox today:

[   98.788039]  =======================
[   98.788039] Kernel panic - not syncing: softlockup: hung tasks

it's not specific enough to bisect it precisely, but excluding all these 
commits from x86/pat:

6b5b551: x86: handle error returns in set_memory_*()
5f25f5b: x86: track memtype for RAM in page struct
3196625: x86, cpa: global flush tlb after splitting large page and before doing cpa
79abc89: x86, cpa: remove cpa pool code
e96d59b: x86, cpa: fix taking the pgd_lock with interrupts off
888fdd9: x86, cpa: dont use large pages for kernel identity mapping with DEBUG_PAGEALLOC
e579af6: x86, cpa: make the kernel physical mapping initialization a two pass sequence
c86eefc: x86, cpa: remove USER permission from the very early identity mapping attribute
e8729a5: x86, cpa: rename PTE attribute macros for kernel direct mapping in early boot

makes the lockups go away.

i've pushed out the broken tree into tip/tmp.x86.pat.broken 
(2.6.27-rc6-tip-00431-g506f75d-dirty), you should be able to test the 
attached config with that specific tree. (i'll send the full crashlog in 
private mail, it's too large for lkml)

hmm. Me the culprit :(

There are more places in the kernel which takes pgd_lock using
spin_lock_irqsave() construct. Need to fix all such places
to use spin_lock(). Will fix it and send a more tested patch set
early next week, after I return from the conferences.

thanks,

[patch 4/7] x86, cpa: dont use large pages for kernel identity mapping with DEBUG_PAGEALLOC

[Suresh Siddha]

[-- Attachment #1: no_lp_identity_mapping_debug_pgalloc.patch --]
[-- Type: text/plain, Size: 4109 bytes --]

Don't use large pages for kernel identity mapping with DEBUG_PAGEALLOC.
This will remove the need to split the large page for the
allocated kernel page in the interrupt context.

This will simplify cpa code(as we don't do the split any more from the
interrupt context). cpa code simplication in the subsequent patches.
