2007-08-30[SPARC64]: Fix several bugs in MSI handling.David S. Miller3-14/+30
1) sun4{u,v}_build_msi() have improper return value handling. We should always return negative error codes, instead of using the magic value "0" which could in fact be a valid MSI number. 2) sun4{u,v}_build_msi() should return -ENOMEM instead of calling prom_prom() halt with kzalloc() of the interrupt data fails. 3) We 'remembered' the MSI number using a singleton in the struct device archdata area, this doesn't work for MSI-X which can cause multiple MSIs assosciated with one device. Delete that archdata member, and instead store the MSI number in the IRQ chip data area. Signed-off-by: David S. Miller <davem@davemloft.net>
2007-08-30[SPARC64]: Fix type and constant sizes wrt. sun4u IMAP/ICLR handling.David S. Miller1-1/+1
Sometimes we were using 32-bit values and the top bits were getting inadvertantly chopped off. This will matter for the forthcoming Fire controller MSI support. Signed-off-by: David S. Miller <davem@davemloft.net>

During GPIO testing on PiMX1 board there has been revealed problem with some pins input functions. The GIUS bit has to be set for inputs to work reliably too. It is surprising that input worked on some inputs with incorrect setup before. DR is not mandatory, but it ensures stable constant level on internal traces.

2007-08-30[POWERPC] spufs: Don't call spu_run_init from spu_reacquire_runnableAndre Detsch1-5/+1
This fixes a major bug which was happening when a SPU thread advances its execution right after being restored to a SPU. A potentially outdated NPC value was being (re)written to the SPU. So, spu_run_init, in this case, was either not doing anything relevant, or breaking the execution of the SPU thread. This fixes a common problem of losing a mailbox write when it was done to a saved context.

2007-08-30[POWERPC] spufs: Fix update of mailbox status register during backed wbox writeArnd Bergmann1-1/+2
When a process writes into the inbound spu mailbox (wbox) while the context is saved, we accidentally break the contents of the mb_stat_R register by clearing other entries of the mailbox status register. This can cause the user side to hang. This change fixes the problem by only altering the appropriate bits of the mailbox status register during a backing-store write.

2007-08-30[POWERPC] spu_manage: fix spu_unit_number for celleb device treeChristian Krafft1-0/+8
This fixes a regression introduced with 2.6.23-rc4 after on some confusion about the device tree interfaces. IBM QS21 device trees provide "physical-id", so we changed the code to run on that and remain compatible with all IBM machines. However, the Toshiba Celleb device tree provides the "unit-id" property, which was in the Linux code, but never used in this way on IBM hardware. Legacy device tree used the reg property for the physical id of an spe. This patch fixes find_spu_unit_number to look for the spu id in that order. The length is checked to avoid misinterpretation in case the attributes unit-id or reg do not contain the id.

2007-08-28[POWERPC] Flush registers to proper task contextKumar Gala1-3/+3
When we flush register state for FP, Altivec, or SPE in flush_*_to_thread we need to respect the task_struct that the caller has passed to us. Most cases we are called with current, however sometimes (ptrace) we may be passed a different task_struct. This showed up when using gdbserver debugging a simple program that used floating point. When gdb tried to show the FP regs they all showed up as 0, because the child's FP registers were never properly flushed to memory. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2007-08-28[ARM] 4557/1: Fix PXA irq gpio initializationSamuel1-1/+1
As pointed out by Jrgen, we are overflowing the number of GPIOs in pxa_init_irq_gpio(). I'm seeing the same problem on my HTC Universal PXA270 based PDA. According to Eric, the function argument is the number of GPIOs, so we should keep the semantics and reduce the number of iteration by 1.
