This is one of a series of patches I plan to gradually trickle into the tree which eliminates almost all remaining use of pci_find_* and lets me build a pci_find_* free kernel for all but some obscure ISDN and SCSI drivers. This is important as all pci_find_* users are not hotplug safe - even if they are not the device being plugged.

ppc can boot one single binary on prep, chrp and pmac boards. ppc64 can boot one single binary on pseries and G5 boards. pmac has no legacy io, probing for PC style legacy hardware (or accessing the legacy io area regulary) may lead to a hard crash: * add check for parport_pc, exit on pmac. 32bit chrp has no ->check_legacy_ioport, the probe is always called. 64bit chrp has check_legacy_ioport, check for a "parallel" node * add check for isapnp, only PReP boards may have real ISA slots. 32bit PReP will have no ->check_legacy_ioport, the probe is always called. * update code in i8042_platform_init. Run ->check_legacy_ioport first, always call request_region. No functional change. Remove whitespace before i8042_reset init.

Powerpc already has a directed yield for CONFIG_PREEMPT="n". To make it work with CONFIG_PREEMPT="y" as well the _raw_{spin,read,write}_relax primitives need to be defined to call __spin_yield() for spinlocks and __rw_yield() for rw-locks.

由 Martin Schwidefsky 提交于
On systems running with virtual cpus there is optimization potential in regard to spinlocks and rw-locks. If the virtual cpu that has taken a lock is known to a cpu that wants to acquire the same lock it is beneficial to yield the timeslice of the virtual cpu in favour of the cpu that has the lock (directed yield). With CONFIG_PREEMPT="n" this can be implemented by the architecture without common code changes. Powerpc already does this. With CONFIG_PREEMPT="y" the lock loops are coded with _raw_spin_trylock, _raw_read_trylock and _raw_write_trylock in kernel/spinlock.c. If the lock could not be taken cpu_relax is called. A directed yield is not possible because cpu_relax doesn't know anything about the lock. To be able to yield the lock in favour of the current lock holder variants of cpu_relax for spinlocks and rw-locks are needed. The new _raw_spin_relax, _raw_read_relax and _raw_write_relax primitives differ from cpu_relax insofar that they have an argument: a pointer to the lock structure.

I was playing with LED triggers when I noticed that changing from heartbeat (or ide-disk) to "none" at the right moment would leave the LED stuck on. This is easy to reproduce by doing "find / >/dev/null" with the ide-disk trigger enabled and then switching to "none". Here is a patch that fixes the problem by explicitly turning the LED off after removing the existing trigger.

The driver for /proc/config.gz consumes rather a lot of memory and it is in fact possible to build it as a module. In some ways this is a bit risky, because the .config which is used for compiling kernel/configs.c isn't necessarily the same as the .config which was used to build vmlinux. But OTOH the potential memory savings are decent, and it'd be fairly dumb to build your configs.o with a different .config.
