db46868128 [PATCH] x86-64/i386: Revert cpuinfo siblings behaviour back to 2.6.10
Only display physical id/siblings when there are siblings or dual core.

In 2.6.11 I accidentially broke it and it was always displaying these
fields But for compatibility to all these /proc parsers around it is better
to do it in the old way again.

ecd02dddd1 [PATCH] i386: Use loaddebug macro consistently
This moves the macro loaddebug from asm-i386/suspend.h to
asm-i386/processor.h, which is the place that makes sense for it to be
defined, removes the extra copy of the same macro in
arch/i386/kernel/process.c, and makes arch/i386/kernel/signal.c use the
macro in place of its expansion.

This is a purely cosmetic cleanup for the normal i386 kernel.  However, it
is handy for Xen to be able to just redefine the loaddebug macro once
instead of also changing the signal.c code.

89e09f5ebb [PATCH] ppc64: remove -fno-omit-frame-pointer
During some code inspection using gcc 4.0 I noticed a stack frame was being
created for a number of functions that didnt require it.  For example:

c0000000000df944 <._spin_unlock>:
c0000000000df944:       fb e1 ff f0     std     r31,-16(r1)
c0000000000df948:       f8 21 ff c1     stdu    r1,-64(r1)
c0000000000df94c:       7c 3f 0b 78     mr      r31,r1
c0000000000df950:       7c 20 04 ac     lwsync
c0000000000df954:       e8 21 00 00     ld      r1,0(r1)
c0000000000df958:       38 00 00 00     li      r0,0
c0000000000df95c:       90 03 00 00     stw     r0,0(r3)
c0000000000df960:       eb e1 ff f0     ld      r31,-16(r1)
c0000000000df964:       4e 80 00 20     blr

It turns out we are adding -fno-omit-frame-pointer to ppc64 which is
causing the above behaviour.  Removing that flag results in much better
code:

c0000000000d5b30 <._spin_unlock>:
c0000000000d5b30:       7c 20 04 ac     lwsync
c0000000000d5b34:       38 00 00 00     li      r0,0
c0000000000d5b38:       90 03 00 00     stw     r0,0(r3)
c0000000000d5b3c:       4e 80 00 20     blr

We dont require a frame pointer to debug on ppc64, so remove it.

187335a4ec [PATCH] ppc64: Detect altivec via firmware on unknown CPUs
This patch adds detection of the Altivec capability of the CPU via the
firmware in addition to the cpu table.  This allows newer CPUs that aren't
in the table to still have working altivec support in the kernel.

It also fixes a problem where if a CPU isn't recognized as having altivec
features, and takes an altivec unavailable exception due to userland
issuing altivec instructions, the kernel would happily enable it and
context switch the registers ...  but not all of them (it would basically
forget vrsave).  With this patch, the kernel will refuse to enable altivec
when the feature isn't detected for the CPU (SIGILL).

547ee84cea [PATCH] ppc64: Improve mapping of vDSO
This patch reworks the way the ppc64 is mapped in user memory by the kernel
to make it more robust against possible collisions with executable
segments.  Instead of just whacking a VMA at 1Mb, I now use
get_unmapped_area() with a hint, and I moved the mapping of the vDSO to
after the mapping of the various ELF segments and of the interpreter, so
that conflicts get caught properly (it still has to be before
create_elf_tables since the later will fill the AT_SYSINFO_EHDR with the
proper address).

While I was at it, I also changed the 32 and 64 bits vDSO's to link at
their "natural" address of 1Mb instead of 0.  This is the address where
they are normally mapped in absence of conflict.  By doing so, it should be
possible to properly prelink one it's been verified to work on glibc.

7bbd827750 [PATCH] ppc64: very basic desktop g5 sound support
This patch hacks the current PowerMac Alsa driver to add some basic support
of analog sound output to some desktop G5s.  It has severe limitations
though:

 - Only 44100Khz 16 bits
 - Only work on G5 models using a TAS3004 analog code, that is early
   single CPU desktops and all dual CPU desktops at this date, but none
   of the more recent ones like iMac G5.
 - It does analog only, no digital/SPDIF support at all, no native
   AC3 support

Better support would require a complete rewrite of the driver (which I am
working on, but don't hold your breath), to properly support the diversity
of apple sound HW setup, including dual codecs, several i2s busses, all the
new codecs used in the new machines, proper clock switching with digital,
etc etc etc...

This patch applies on top of the other PowerMac sound patches I posted in
the past couple of days (new powerbook support and sleep fixes).  

Note: This is a FAQ entry for PowerMac sound support with TI codecs: They
have a feature called "DRC" which is automatically enabled for the internal
speaker (at least when auto mute control is enabled) which will cause your
sound to fade out to nothing after half a second of playback if you don't
set a proper "DRC Range" in the mixer.  So if you have a problem like that,
check alsamixer and raise your DRC Range to something reasonable.

Note2: This patch will also add auto-mute of the speaker when line-out jack
is used on some earlier desktop G4s (and on the G5) in addition to the
headphone jack.  If that behaviour isn't what you want, just disable
auto-muting and use the manual mute controls in alsamixer.

54095a6ec7 [PATCH] ppc32: Fix a problem with NTP on !(chrp||gemini)
The following problem was found by Giovambattista Pulcini
<gpulcini@swintel.it>, who also provided a partial patch, and this has been
verified by our time guru Gabriel Paubert <paubert@iram.es>.

The problem is that in do_settimeofday() we always set time_state to
TIME_ERROR and except on two platforms, never re-set it.  This meant that
ntp_gettime() and ntp_adjtime() always returned TIME_ERROR, incorrectly. 
Based on Gabriel's analysis, time_state is used for leap-second processing,
and ppc shouldn't be mucking with it.

f50b153b19 [PATCH] ppc32: Support 36-bit physical addressing on e500
To add support for 36-bit physical addressing on e500 the following changes
have been made.  The changes are generalized to support any physical address
size larger than 32-bits:

* Allow FSL Book-E parts to use a 64-bit PTE, it is 44-bits of pfn, 20-bits
  of flags.

* Introduced new CPU feature (CPU_FTR_BIG_PHYS) to allow runtime handling of
  updating hardware register (SPRN_MAS7) which holds the upper 32-bits of
  physical address that will be written into the TLB.  This is useful since
  not all e500 cores support 36-bit physical addressing.

* Currently have a pass through implementation of fixup_bigphys_addr

* Moved _PAGE_DIRTY in the 64-bit PTE case to free room for three additional
  storage attributes that may exist in future FSL Book-E cores and updated
  fault handler to copy these bits into the hardware TLBs.

0c541b4406 [PATCH] ppc32: Fix AGP and sleep again
My previous patch that added sleep support for uninorth-agp and some AGP
"off" stuff in radeonfb and aty128fb is breaking some configs.  More
specifically, it has problems with rage128 setups since the DRI code for
these in X doesn't properly re-enable AGP on wakeup or console switch
(unlike the radeon DRM).

This patch fixes the problem for pmac once for all by using a different
approach.  The AGP driver "registers" special suspend/resume callbacks with
some arch code that the fbdev's can later on call to suspend and resume
AGP, making sure it's resumed back in the same state it was when suspended.
 This is platform specific for now.  It would be too complicated to try to
do a generic implementation of this at this point due to all sort of weird
things going on with AGP on other architectures.  We'll re-work that whole
problem cleanly once we finally merge fbdev's and DRI.

In the meantime, please apply this patch which brings back some r128 based
laptops into working condition as far as system sleep is concerned.

35b535d9cc [PATCH] ppc32: ppc4xx_pic - add acknowledge when enabling level-sensitive IRQ
This patch adds interrupt acknowledge to the PPC4xx PIC enable_irq
implementation for level-sensitive IRQ sources.  This helps in cases when
enable/disable_irq is used in interrupt handlers for hardware, which
requires IRQ acknowledge to be issued from non-interrupt context (e.g. 
when actual ACK in device needs an I2C transaction).  For such strange
hardware, interrupt handler disables IRQ and defers actual ACK to some
other context.  When this happens, IRQ is enabled again.  For
level-sensitive sources we get spurious triggering right after IRQ is
enabled.  This patch fixes this.

2d137c24e9 [PATCH] arm: fix SIGBUS handling
)


From: Russell King <rmk+lkml@arm.linux.org.uk>

ARM wasn't raising a SIGBUS with a siginfo structure.  Fix
__do_user_fault() to allow us to use it for SIGBUS conditions, and arrange
for the sigbus path to use this.

We need to prevent the siginfo code being called if we do not have a user
space context to call it, so consolidate the "user_mode()" tests.

Thanks to Ian Campbell who spotted this oversight.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
