2006-03-17[PATCH] ppc: Fix platform_notify functions marked __initAdrian Cox
While adding USB support to an MV64360 based board this week, I discovered that all MV64x60 boards in the kernel have platform_notify functions marked with __init. This causes an oops if a device is added after boot. The patch below removes the __init markers. I do not have all these boards to test on, but the change seems very unlikely to break anything else.

2006-03-08powerpc: Fix various syscall/signal/swapcontext bugsPaul Mackerras
A careful reading of the recent changes to the system call entry/exit paths revealed several problems, plus some things that could be simplified and improved: * 32-bit wasn't testing the _TIF_NOERROR bit in the syscall fast exit path, so it was only doing anything with it once it saw some other bit being set. In other words, the noerror behaviour would apply to the next system call where we had to reschedule or deliver a signal, which is not necessarily the current system call. * 32-bit wasn't doing the call to ptrace_notify in the syscall exit path when the _TIF_SINGLESTEP bit was set. * _TIF_RESTOREALL was in both _TIF_USER_WORK_MASK and _TIF_PERSYSCALL_MASK, which is odd since _TIF_RESTOREALL is only set by system calls. I took it out of _TIF_USER_WORK_MASK. * On 64-bit, _TIF_RESTOREALL wasn't causing the non-volatile registers to be restored (unless perhaps a signal was delivered or the syscall was traced or single-stepped). Thus the non-volatile registers weren't restored on exit from a signal handler. We probably got away with it mostly because signal handlers written in C wouldn't alter the non-volatile registers. * On 32-bit I simplified the code and made it more like 64-bit by making the syscall exit path jump to ret_from_except to handle preemption and signal delivery. * 32-bit was calling do_signal unnecessarily when _TIF_RESTOREALL was set - but I think because of that 32-bit was actually restoring the non-volatile registers on exit from a signal handler. * I changed the order of enabling interrupts and saving the non-volatile registers before calling do_syscall_trace_leave; now we enable interrupts first.

2006-02-24[PATCH] powerpc: fix altivec_unavailable_exception OopsesAlan Curry
altivec_unavailable_exception is called without setting r3... it looks like the r3 that actually gets passed in as struct pt_regs *regs is the undisturbed value of r3 at the time the altivec instruction was encountered. The user actually gets to choose the pt_regs printed in the Oops! This fixes the oops by passing the correct pt_regs pointer to altivec_unavailable_exception.

2006-02-10[PATCH] ppc32: Make platform devices being able to assign functionsVitaly Bordug
Implemented by modification of the .name field of the platform device, when PDs with the same names are to be used within different drivers, as <device_name> -> <device_name>:<function> Corresponding drivers should change the .name in struct device_driver to reflect upper of course. Added ppc_sys_device_disable/enable function set, making it easier to disable all the inexistent/not utilized platform device way pdevs. By the check of the "disabled" bit in the config field of ppc_sys_specs, disabled platform devices will be either added/removed from the bus, or simply not registered on it, depending on the time when disable/enable call asserted. The default behaviour when nothing is disabled/enabled will be "all devices are enabled", which is the same as before. Also helper platform_notify_map function added, making assignment of board-specific platform_info more consistent and generic.

platfom bus. This patch only deals with the serial port definitions as there is no support for any other xilinx IP cores in the kernel tree at the moment. Board specific configuration moved out of virtex.[ch] and into the xparameters.h wrapper. This also prepares for the transition to the flattened device tree model. When the bootloader provides a device tree generated from an xparameters.h files, the kernel will no longer need xparameters/*. The platform bus will get populated with data from the device tree, and the device drivers will be automatically connected to the devices. Only the bootloader (or ppcboot) will need xparameters directly. Signed-off-by: Grant C. Likely <grant.likely@secretlab.ca> Signed-off-by: Paul Mackerras <paulus@samba.org>
