ppc64 sys_ipc breakage in 2.6.34-rc2

I chased down a fail on ppc64 on 2.6.34-rc2 where an application that uses shared memory was getting a SEGV. Commit baed7fc9b580bd3fb8252ff1d9b36eaf1f86b670 (Add generic sys_ipc wrapper) changed the second argument from an unsigned long to an int. When we call shmget the system call wrappers for

Hi Grant, thanks for the comments, I solved some of the points you mentioned. I need some more time to work on the others. In the meantime I send the intermediate version. Grant Likely wrote: > 2010/3/13 Németh Márton : [...] >> + mem...@4000 { >> + device_type = "memory"

[PATCH 01/10] irq: move some interrupt arch_* functions into struct irq_chip.

From: Ian Campbell Move arch_init_copy_chip_data and arch_free_chip_data into function pointers in struct irq_chip since they operate on irq_desc->chip_data. arch_init_chip_data cannot be moved into struct irq_chip because irq_desc->chip is not known at the time the irq_desc is setup. Instead re

could you help me the GPIO problem on MPC8323?

hi,all: i saw peter's mpc8xxx_gpio.c in kernel 2.6.31. it seems that file can only be used on 831x and others, but not mpc8323. my platform is mpc8323, how can i use the GPIO? i also found "QE GPIO Support" and "Support for simple, memory-mapped GPIO controllers" selection, would that be helpfu
