2008-07-30sticore: don't activate unsupported GSC STI cards on HPPAHelge Deller
On HPPA there exists some older GSC graphics cards, which need special graphic-card-BIOS patching to become supported. Since we don't have yet implemented the patching, it's better to detect such cards in advance, inform to the user that there are known problems and to not activate the card. Problematic GSC cards and BIOS versions are: * Hyperdrive/Hyperbowl (A4071A) graphics card series: * ID = 0x2BCB015A (Version 8.04/8) * ID = 0x2BCB015A (Version 8.04/11) * Thunder 1 VISUALIZE 48 card: * ID = 0x2F23E5FC (Version 8.05/9) * Thunder 2 VISUALIZE 48 XP card: * ID = 0x2F8D570E (Version 8.05/12) * Some Hyperion and ThunderHawk GSC cards Further details are described here: http://parisc-linux.org/faq/graphics-howto.html Signed-off-by: Helge Deller <deller@gmx.de> Cc: Kyle McMartin <kyle@mcmartin.ca> Cc: Krzysztof Helt <krzysztof.h1@poczta.fm> Cc: "Antonino A.

2008-07-30cpufreq acpi: only call _PPC after cpufreq ACPI init funcs got called alreadyThomas Renninger
Ingo Molnar provided a fix to not call _PPC at processor driver initialization time in "[PATCH] ACPI: fix cpufreq regression" (git commit e4233dec749a3519069d9390561b5636a75c7579) But it can still happen that _PPC is called at processor driver initialization time. This patch should make sure that this is not possible anymore.

2008-07-28spi_s3c24xx: really assign busnumBen Dooks
The original "Pass the bus number we expect the S3C24XX SPI driver to attach to via the platform data." [1] patch was mis-sent, and missed two important parts of the diff, which was to actually set the bus_num field and add the relevant field to the platform data. The previous commit 50f426b55d919dd017af35bb6a08753d1f262920 promised to add a bus_num field, but failed to include the two hunks that added this field to include/asm-arm/arch-s3c2410/spi.h and then pass it to the spi core when creating the new master field in drivers/spi/spi_s3c24xx.c.

2008-07-28mpc52xx_psc_spi: fix block transferLuotao Fu
The block transfer routine in the mpc52xx psc spi driver misinterpret the datasheet. According to the processor datasheet the chipselect is held as long as the EOF is not written. Theoretically blocks of any sizes can be transferred in this way. The old routine however writes an EOF after every word, which has the size of size_of_word. This makes the transfer slow. Also fixed some duplicate code.

2008-07-28ACPI/CPUIDLE: prevent setting pm_idle to NULLThomas Gleixner
pm_idle_save resp. pm_idle_old can be NULL when the restore code in acpi_processor_cst_has_changed() resp. cpuidle_uninstall_idle_handler() is called. This can set pm_idle unconditinally to NULL, which causes the kernel to panic when calling pm_idle in the x86 idle code. This was covered by an extra check for !pm_idle in the x86 idle code, which was removed during the x86 idle code refactoring. Instead of restoring the pm_idle check in the x86 code prevent the acpi/cpuidle code to set pm_idle to NULL.

2008-07-28ipwireless: Increase PPP outgoing queue sizeDavid Sterba
ipwireless: Increase PPP outgoing queue size Increase default size of PPP outgoing queue. Currently set to 1, which means that a packet quickly following another pushed by PPP must wait until hardware actually sends the previous and PPP has to be waken up by ppp_wakeup(). This slows down upstream. Now PPP can push more packets at once which get buffered inside driver and pushed immediatelly to hardware when previous packet is out. Experiments show that size = 10 is quite good for all connection types (GPRS/EDGE/UMTS) and gains 4 KB/sec of upload for UMTS for batch uploads. Need for higher queue size than 10 occures in only < 0.1 % of cases.
