2008-01-26[ARM] 4734/1: at91sam9263ek: include IRQ for Ethernet PHYDavid Brownell
On the at92sam9263ek board, tell the MACB driver the IRQ used by its PHY. This patch is taken from Andrew Victor's 2.6.23-at91 patchset; it matches board schematics. (But it's currently a NOP since the MACB driver doesn't yet use PHY irqs.) Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2008-01-26[ARM] 4646/1: AT91: configurable HZ, default to 128David Brownell
This makes HZ configurable on AT91, following the model used on OMAP. It defaults to a power of two on AT91rm9200 chips, avoiding rounding errors which come from dividing a 32 KiHz clock to generate scheduler irqs; and uses 100 on AT91sam926x chips, using MCK/16 (multi-MHZ).

2008-01-26[ARM] 4770/1: GLAN Tank: correct physmap_flash_data width fieldGordon Farquharson
This patch is required, in conjunction with the patch submitted to linux-mtd [1], to access the flash memory device in the GLAN Tank. Without the patches, the boot log shows physmap platform flash device: 00080000 at f0000000 ... physmap-flash physmap-flash.0: map_probe failed whereas with the patches, the boot log shows physmap platform flash device: 00080000 at f0000000 Found: ST M29W400DB physmap-flash.0: Found 1 x16 devices at 0x0 in 16-bit bank number of JEDEC chips: 1 cfi_cmdset_0002: Disabling erase-suspend-program due to code brokenness. ... cmdlinepart partition parsing not available Searching for RedBoot partition table in physmap-flash.0 at offset 0x70000 No RedBoot partition table detected in physmap-flash.0 The change made by this patch is required because the ST M29W400DB flash memory chip in the GLAN Tank is used in 16 bit bus mode (~BYTE pin is high when the board is powered on).

2008-01-26[ARM] 4584/2: ARMv7: Add Advanced SIMD (NEON) extension supportCatalin Marinas
This patch enables the use of the Advanced SIMD (NEON) extension on ARMv7. The NEON technology is a 64/128-bit hybrid SIMD architecture for accelerating the performance of multimedia and signal processing applications. The extension shares the registers with the VFP unit and enabling/disabling and saving/restoring follow the same rules. In addition, there are instructions that do not have the appropriate CP number encoded, the checks being made in the call_fpe function.

2008-01-26[ARM] 4583/1: ARMv7: Add VFPv3 supportCatalin Marinas

2008-01-26[ARM] 4582/2: Add support for the common VFP subarchitectureCatalin Marinas
This patch allows the VFP support code to run correctly on CPUs compatible with the common VFP subarchitecture specification (Appendix B in the ARM ARM v7-A and v7-R edition). It implements support for VFP subarchitecture 2 while being backwards compatible with subarchitecture 1. On VFP subarchitecture 1, the arithmetic exceptions are asynchronous (or imprecise as described in the old ARM ARM) unless the FPSCR.IXE bit is 1. The exceptional instructions can be read from FPINST and FPINST2 registers. With VFP subarchitecture 2, the arithmetic exceptions can also be synchronous and marked by the FPEXC.DEX bit (the FPEXC.EX bit is cleared). CPUs implementing the synchronous arithmetic exceptions don't have the FPINST and FPINST2 registers and accessing them would trigger and undefined exception. Note that FPEXC.EX bit has an additional meaning on subarchitecture 1 - if it isn't set, there is no additional information in FPINST and FPINST2 that needs to be saved at context switch or when lazy-loading the VFP state of a different thread. The patch also removes the clearing of the cumulative exception flags in FPSCR when additional exceptions were raised. It is up to the user application to clear these bits.

2008-01-26[ARM] 4669/1: ep93xx: simplify GPIO code and cleanupsHerbert Valerio Riedel
This patch renumbers the (virtual) GPIO line numbering to have all irq-capable gpio lines <= EP93XX_GPIO_LINE_MAX_IRQ by swapping the port f range with the port c range; This simplifies code such as #define IRQ_EP93XX_GPIO(x) (64 + (((x) + (((x) >> 2) & 8)) & 0x1f)) or if (line >= 0 && line < 16) { /* Port A/B */ } else if (line >= 40 && line < 48) { /* Port F */ } considerably; in addition to the renumbering this patch also introduces macro constants EP93XX_GPIO_LINE_MAX_IRQ and EP93XX_GPIO_LINE_MAX, and replaces most magic numbers by those and invocations of gpio_to_irq()/irq_to_gpio().

In s390's spin_lock_irqsave, interrupts remain disabled while spinning.

2008-01-26[S390] Use diag308 subcodes 3 and 6 for reboot and dump when possible.Michael Holzheu
This patch fixes a problem with the following scenario: 1. Linux booted from DASD "A" 2. Reboot from DASD "B" using "/sys/firmware/reipl/ccw/device" 3. Reboot DASD "B" Without this patch in step 3 on newer s390 systems under LPAR instead of DASD "B", DASD "A" will be booted. The reason is that in step 2 we use CCW reipl and in step 3 we use DIAG308 (subcode 3) reipl. DIAG308 does not notice the CCW reipl and still thinks that it has to reboot DASD "A".

2008-01-26[S390] vmemmap: allocate struct pages before 1:1 mappingChristian Borntraeger
We have seen an oops in an OOM situation, where show_mem tried to access the struct page of a dcss segment. The vmemmap code has already created the 1:1 mapping but failed allocating the struct pages. In the OOM case, show_mem now walks the memory. It uses pfn_valid to detect if it may access the struct page. In the case described above, the mapping was established and pfn_valid returned true. As the struct pages were not allocated, the kernel oopsed. We have to ensure that we have created the struct pages, before we add a mapping pointing to the pages.
