* [PATCH] net/fs_enet/mii-fec: Use PHY_POLL instead of hard coded '-1'
From: Wolfram Sang @ 2009-05-08 14:00 UTC (permalink / raw)
  To: w.sang; +Cc: netdev, linuxppc-dev, Vitaly Bordug

Initialize the irq-table with PHY_POLL. '-1' means the same now, but is
hardly maintainable.

* [PATCH 08/15] powerpc/cell: Extract duplicated IOPTE_* to <asm/iommu.h>
From: Geert Uytterhoeven @ 2009-05-08 14:01 UTC (permalink / raw)
  To: Benjamin Herrenschmidt
  Cc: linux-fbdev-devel, Arnd Bergmann, linux-kernel, linuxppc-dev,
	Geert Uytterhoeven, cbe-oss-dev
In-Reply-To: <1241791284-11490-8-git-send-email-Geert.Uytterhoeven@sonycom.com>

Both arch/powerpc/platforms/cell/iommu.c and arch/powerpc/platforms/ps3/mm.c
contain the same Cell IOMMU page table entry definitions. Extract them and move
them to <asm/iommu.h>.
This also allows them to be used by drivers.

* [PATCH] powerpc/fsl: Removed reg property from 85xx/86xx soc node
From: Kumar Gala @ 2009-05-08 14:05 UTC (permalink / raw)
  To: linuxppc-dev

Between the addition of the ecm/mcm law nodes and the fact that the
get_immrbase() has been using the range property of the SoC to determine
the base address of CCSR space we no longer need the reg property at
the soc node level.  It has been ill specified and varied between device
trees to cover either the {e,m}cm-law node, some odd subset of CCSR
space or all of CCSR space.

* [PATCH v3] powerpc: Keep track of emulated instructions if debugfs is enabled
From: Geert Uytterhoeven @ 2009-05-08 14:15 UTC (permalink / raw)
  To: Linux/PPC Development

Counters for the various classes of emulated instructions are available under
/sys/kernel/debug/powerpc/emulated_instructions (assumed debugfs is mounted on
/sys/kernel/debug).  Optionally (controlled by
/sys/kernel/debug/powerpc/emulated_instructions/do_warn), rate-limited warnings
can be printed to the console when instructions are emulated.

Signed-off-by: Geert Uytterhoeven <Geert.Uytterhoeven@sonycom.com>
---
Tested on ppc64 (ps3) and ppc32 (sequoia) using mfpvr.

v3:
  - add generic unaligned
  - switch from sysfs + sysctl to debugfs. All virtual files now show up under
    /sys/kernel/debug/powerpc/emulated_instructions (assumed debugfs mounted on
    /sys/kernel/debug)
  - enable the printing of rate-limited warnings by writing a non-zero value to
    /sys/kernel/debug/powerpc/emulated_instructions/do_warn
  - switch from per-CPU to system-wide counters
  - always use 32-bit counters (was 64-bit on ppc64)
  - counters are writable, i.e. can be reset (by root)

v2:
  - arch/powerpc/kernel/sysfs.c is now compiled on ppc32, so we can provide
    counters in sysfs on ppc32, too,
  - WARN_EMULATED() is a no-op if CONFIG_SYSCTL is disabled,
  - Add warnings for altivec,
  - Add warnings for recently introduced emulation of vsx and isel
    instructions.

Dear All,

I am looking for a patch which introduces lzma compression or suppresses the
standard gzip compression for the initramfs.

I would be grateful for any hint.

It's already in the mainline kernel, e.g.:

commit 30d65dbfe3add7f010a075991dc0bfeaebb7d9e1
Author: Alain Knaff <alain@knaff.lu>
Date:   Sun Jan 4 22:46:17 2009 +0100

    bzip2/lzma: config and initramfs support for bzip2/lzma decompression
    
    Impact: New code for initramfs decompression, new features
    
    This is the second part of the bzip2/lzma patch
    
    The bzip patch is based on an idea by Christian Ludwig, includes support for
    compressing the kernel with bzip2 or lzma rather than gzip. Both
    compressors give smaller sizes than gzip.  Lzma's decompresses faster
    than bzip2.
    
    It also supports ramdisks and initramfs' compressed using these two
    compressors.
    
    The functionality has been successfully used for a couple of years by
    the udpcast project
    
    This version applies to "tip" kernel 2.6.28
    
    This part contains:
    - support for new compressions (bzip2 and lzma) in initramfs and
    old-style ramdisk
    - config dialog for kernel compression (but new kernel compressions
    not yet supported)
    
    Signed-off-by: Alain Knaff <alain@knaff.lu>
    Signed-off-by: H. Peter Anvin <hpa@zytor.com>

For older kernel versions, you can backport it by git cherry-picking the
commits you need.

Personally, I'd rather see the printks converted to pr_info()/pr_cont().

That is fine by me, but since it is known that it will eventually
support both, I'd like it to be renamed to 5xxx before it is merged to
avoid a later rename patch.

    Is there an example somewhere that shows building a device tree on

    As our products move forward it becomes increasingly clear that

A whole device tree?  I don't think so.  U-Boot does manipulate quite
a few properties, but it assume that the DTS lists all the devices.

Remember, one of the primary purposes of the DTS is to list devices
that cannot be probed.

you can look at the source to SLOF or u-boot to see cases of building  
nodes on the fly.

I guess nobody has any idea...

I'll just make INET_LRO a bool to fix this.

At least on x86-64 gettimeofday() (and time(2)) work inside seccomp because 
they're vsyscalls that run in ring 3 only.
