14 years ago[PATCH] spufs: fix for CONFIG_NUMA
Joel H Schopp [Mon, 1 May 2006 19:16:11 +0000]
[PATCH] spufs: fix for CONFIG_NUMA

Based on an older patch from  Mike Kravetz <kravetz@us.ibm.com>

We need to have a mem_map for high addresses in order to make fops->no_page
work on spufs mem and register files.  So far, we have used the
memory_present() function during early bootup, but that did not work when
CONFIG_NUMA was enabled.

We now use the __add_pages() function to add the mem_map when loading the
spufs module, which is a lot nicer.

[PATCH] sparsemem interaction with memory add bug fixes

This patch fixes two bugs with the way sparsemem interacts with memory add.
They are:

- memory leak if memmap for section already exists

- calling alloc_bootmem_node() after boot

These bugs were discovered and a first cut at the fixes were provided by

Christoph Lameter [Mon, 1 May 2006 19:16:08 +0000]
[PATCH] page migration: Fix fallback behavior for dirty pages

Currently we check PageDirty() in order to make the decision to swap out
the page.  However, the dirty information may be only be contained in the
ptes pointing to the page.  We need to first unmap the ptes before checking
for PageDirty().  If unmap is successful then the page count of the page
will also be decreased so that pageout() works properly.

This is a fix necessary for 2.6.17.  Without this fix we may migrate dirty
pages for filesystems without migration functions.  Filesystems may keep
pointers to dirty pages.  Migration of dirty pages can result in the
filesystem keeping pointers to freed pages.

Unmapping is currently not be separated out from removing all the
references to a page and moving the mapping.  Therefore try_to_unmap will
be called again in migrate_page() if the writeout is successful.  However,
it wont do anything since the ptes are already removed.

The coming updates to the page migration code will restructure the code
so that this is no longer necessary.

Paolo 'Blaisorblade' Giarrusso [Mon, 1 May 2006 19:16:05 +0000]
[PATCH] uml: cleanup unprofile expression and build infrastructure

*) Rather than duplicate in various buggy ways the application of
   CFLAGS_NO_HARDENING and UNPROFILE (which apply to the same files),
   centralize it in Makefile.rules.  UNPROFILE_OBJS mustn't be listed in
   USER_OBJS but are compiled as such.

I've also verified that unprofile didn't work in the current form, because we
set _c_flags directly (using CFLAGS and not USER_CFLAGS, which is wrong),
which is normally used by c_flags, but we also override c_flags for all
USER_OBJS, and there we don't call unprofile.

Instead it only worked for unmap.o, the only one which wasn't a USER_OBJ.

We need to set c_flags (which is not a public Kbuild API) to clear a lot of
compilation flags like -nostdinc which Kbuild forces on everything.

*) Rather than $(CFLAGS_$(notdir $@)), which expands to CFLAGS_anObj.s when
   building "anObj.s", use $(CFLAGS_$(*F).o) which always accesses
   CFLAGS_anObj.o, like done by Kbuild.

*) Make c_flags apply to all targets having the same basename, rather than
   listing .s, .i, .lst and .o, with the use (which I tested) of

$(USER_OBJS:.o=.%): c_flags = ...

and of

 -      $(obj)/unmap.c: _c_flags = ...
 +      $(obj)/unmap.%: _c_flags = ...

At that point dst is still the xfrm_dst for the current SA which
represents an internal flow as far as the IPsec tunnel is concerned.
Since the IP ID is going to sit on the outside of the encapsulated

that the qib structure embedded in the qeth_irq structure needs an alignment
of 256 but kmalloc only guarantees an alignment of 8.  When using SLAB
debugging the alignment of qeth_irq is not sufficient for the embedded qib
structure which causes all users of qdio (qeth and zfcp) to stop working.

So we need to make this option harder to set.  Use CONFIG_EMBEDDED for this.

CONFIG_EMBEDDED isn't really the right thing to use, but there's nothing else

[PATCH] enable X86_PC for HOTPLUG_CPU

CPU_HOTPLUG has race conditions when we use broadcast mode IPI.

- First we introduced no_broadcast option
    (see include/asm-i386/mach-default/mach_ipi.h)

- x86_64 solved it by using physical flat mode (same as bigsmp on i386)
  since this will not use broadcast shortcuts for IPI.

- We switched to use bigsmp on i386 so that we can have same handling as
  x86_64, but apparently this caused an error message, if kernel was
  compiled without X86_GENERICARCH, X86_BIGSMP.  The message "You have >8
  CPUS..." which was bogus and misleading, and only indicated one of the
  above ARCH wasnt selected.

So we do not switch to automatic bigsmp for HOTPLUG_CPU support in i386
until the other related config dependencies for SMP_SUSPEND etc can be done
right.

loader refuses to load such a module, since it needs the address
of the .toc section to use in relocations.

This patch fixes the problem by using the address of the .stubs
section instead, which is an acceptable substitute in this situation.

[PATCH] sound/ppc: snd_pmac_toonie_init should be __init

snd_pmac_toonie_init is only called by __init code and calls __init code
itself.

powerpc/pseries: Tell firmware our capabilities on new machines

This adds code to call a new firmware method to tell the firmware
what machines and capabilities (such as VMX/Altivec) we support.
This will be needed on POWER5+ and POWER6 machines, and it has no
effect on past and current machines.

[PATCH] powerpc: Fix pagetable bloat for hugepages

At present, ARCH=powerpc kernels can waste considerable space in
pagetables when making large hugepage mappings.  Hugepage PTEs go in
PMD pages, but each PMD page maps 256M and so contains only 16
hugepage PTEs (128 bytes of data), but takes up a 1024 byte
allocation.  With CONFIG_PPC_64K_PAGES enabled (64k base page size),
the situation is worse.  Now hugepage PTEs are at the PTE page level
(also mapping 256M), so we store 16 hugepage PTEs in a 64k allocation.

The PowerPC MMU already means that any 256M region is either all
hugepage, or all normal pages.  Thus, with some care, we can use a
different allocation for the hugepage PTE tables and only allocate the
128 bytes necessary.
