2008-06-16Export <linux/a.out.h> to userspace again.David Woodhouse
This seems to have been removed accidentally in commit ed7b1889da256977574663689b598d88950bbd23 ("Unexport asm/page.h"), but wasn't supposed to have been -- the original patch at http://lkml.org/lkml/2007/10/30/144 just moved it from $(header-y) to $(unifdef-y) Signed-off-by: David Woodhouse <dwmw2@infradead.org> Acked-by: Peter Korsgaard <jacmet@sunsite.dk> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2008-06-16Remove last traces of a.out support from ELF loader.David Woodhouse
In commit d20894a23708c2af75966534f8e4dedb46d48db2 ("Remove a.out interpreter support in ELF loader"), Andi removed support for a.out interpreters from the ELF loader, which was only ever needed for the transition from a.out to ELF. This removes the last traces of that support, in particular the inclusion of <linux/a.out.h>.

We only need it for the /sbin/loader hack for OSF/1 executables, and we don't want to include it otherwise. While we're at it, remove the redundant '&& CONFIG_ARCH_SUPPORTS_AOUT' in the ifdef around that code. It's already dependent on __alpha__, and CONFIG_ARCH_SUPPORTS_AOUT is hard-coded to 'y' there.

2008-06-16[MIPS] Lasat: sysctl fixupThomas Horsten
LASAT's sysctl interface was broken, it failed a check during boot because a single entry had a sysctl number and the rest were unnumbered. When I fixed it I noticed that the whole sysctl file needed a spring clean, it was using mutexes where it wasn't needed (it's only needed to protect during writes to the EEPROM), so I moved that stuff out and generally cleaned the whole thing up. So now, LASAT's sysctl/proc interface is working again. Signed-off-by: Thomas Horsten <thomas@horsten.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

2008-06-16[MIPS] Lasat: bring back from the deadThomas Horsten

2008-06-16[MIPS] Bring the SWARM defconfig up to dateMaciej W. Rozycki
The SWARM defconfig file has not been regenerated for over a year now. Here is a patch to bring the file up to date. Additionally some important and sometimes confusing changes happened meanwhile. Here is the list of notable corresponding updates to the configuration: 1. CPU_SB1_PASS_2_2 is now selected rather than CPU_SB1_PASS_1. The latter requires a non-standard -msb1-pass1-workarounds option to be supported by GCC and I am told is quite rare anyway. [Ralf: Afaik -msb1-pass1-workarounds is available only in Monta Vista's special Sibyte gcc 3.0 variant and gcc 3.0 is too old to build a modern kernel anyway.] 2. PHYLIB and BROADCOM_PHY are both built in and NETDEV_1000 enabled as required by SB1250_MAC. 3. USB and USB_OHCI_HCD are enabled as there is an OHCI chip onboard. 4. TMPFS is enabled, because I use it. ;-) Signed-off-by: Maciej W. Rozycki <macro@linux-mips.org> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

2008-06-16[POWERPC] Turn on ATA_SFF so we get SATA_SVW back in defconfigsPaul Mackerras
This enables CONFIG_ATA_SFF in the defconfigs that are intended to work on a G5 powermac, i.e. g5_defconfig and ppc64_defconfig. Since the support for the SATA cell in the K2 chipset is provided by the sata_svw.c driver, and that depends on CONFIG_ATA_SFF, we need to turn that and CONFIG_SATA_SVW back on so we can get to the hard disk on G5s.

2008-06-16[POWERPC] Fix -Os kernel builds with newer gcc versionsKumar Gala
GCC 4.4.x looks to be adding support for generating out-of-line register saves/restores based on: http://gcc.gnu.org/ml/gcc-patches/2008-04/msg01678.html This breaks the kernel if we enable CONFIG_CC_OPTIMIZE_FOR_SIZE. To fix this we add the use the save/restore code from gcc and simplified it down for our needs (integer only). Additionally, we have to link this code into each module. The other solution was to add EXPORT_SYMBOL() which meant going through the trampoline which seemed nonsensical for these out-of-line routines. Finally, we add some checks to prom_init_check.sh to ignore the out-of-line save/restore functions.

GCC 4.4.x looks to be adding support for generating out-of-line register saves/restores based on: http://gcc.gnu.org/ml/gcc-patches/2008-04/msg01678.html This breaks the bootwrapper as we'd need to link with libgcc to get the implementation of the register save/restores. To workaround this issue, we just stole the save/restore code from gcc and simplified it down for our needs (integer only).

2008-06-16powerpc/spufs: fix missed stop-and-signal eventLuke Browning
There is a delay in the transition to the stopped state for class 2 interrupts. In some cases, the controlling thread detects the state of the spu as running, and goes back to sleep resulting in a hung application as the event is missed. This change detects the stop condition and re-generates the wakeup event after a context save. Signed-off-by: Luke Browning <lukebrowning@us.ibm.com> Signed-off-by: Jeremy Kerr <jk@ozlabs.org>

2008-06-16powerpc/spufs: remove class_0_dsisr from spu exception handlingLuke Browning
According to the CBEA, the SPU dsisr is not updated for class 0 exceptions. spu_stopped() is testing the dsisr that was passed to it from the class 0 exception handler, so we return a false positive here. This patch cleans up the interrupt handler and erroneous tests in spu_stopped. It also removes the fields from the csa since it is not needed to process class 0 events.
