2006-10-03[PATCH] restore parport_pc probing on powermacOlaf Hering
The last change for partport_pc did fix the common case for all PowerMacs, but it broke the case for PCI multiport IO cards. In fact, the config option CONFIG_PARPORT_PC_SUPERIO=y lead to a hard crash when cups probed the parport driver. It enables the winbond and smsc probing. Remove the PARPORT_BASE check again, parport_pc_find_nonpci_ports() will take care of it. All powerpc configs should have CONFIG_PARPORT_PC_SUPERIO=n, the code did not find anything on the chrp boards we tested it on.

2006-10-02[PATCH] rename the provided execve functions to kernel_execveArnd Bergmann
Some architectures provide an execve function that does not set errno, but instead returns the result code directly. Rename these to kernel_execve to get the right semantics there. Moreover, there is no reasone for any of these architectures to still provide __KERNEL_SYSCALLS__ or _syscallN macros, so remove these right away.

2006-10-02[PATCH] Kprobes: Make kprobe modules more portableAnanth N Mavinakayanahalli
In an effort to make kprobe modules more portable, here is a patch that: o Introduces the "symbol_name" field to struct kprobe. The symbol->address resolution now happens in the kernel in an architecture agnostic manner. 64-bit powerpc users no longer have to specify the ".symbols" o Introduces the "offset" field to struct kprobe to allow a user to specify an offset into a symbol. o The legacy mechanism of specifying the kprobe.addr is still supported. However, if both the kprobe.addr and kprobe.symbol_name are specified, probe registration fails with an -EINVAL. o The symbol resolution code uses kallsyms_lookup_name(). So CONFIG_KPROBES now depends on CONFIG_KALLSYMS o Apparantly kprobe modules were the only legitimate out-of-tree user of the kallsyms_lookup_name() EXPORT. Now that the symbol resolution happens in-kernel, remove the EXPORT as suggested by Christoph Hellwig o Modify tcp_probe.c that uses the kprobe interface so as to make it work on multiple platforms (in its earlier form, the code wouldn't work, say, on powerpc) Signed-off-by: Ananth N Mavinakayanahalli <ananth@in.ibm.com> Signed-off-by: Prasanna S Panchamukhi <prasanna@in.ibm.com> Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

Powerpc already has a directed yield for CONFIG_PREEMPT="n".

2006-10-01[PATCH] Directed yield: cpu_relax variants for spinlocks and rw-locksMartin Schwidefsky
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.

2006-09-26[PATCH] Standardize pxx_page macrosDave McCracken
One of the changes necessary for shared page tables is to standardize the pxx_page macros. pte_page and pmd_page have always returned the struct page associated with their entry, while pte_page_kernel and pmd_page_kernel have returned the kernel virtual address. pud_page and pgd_page, on the other hand, return the kernel virtual address. Shared page tables needs pud_page and pgd_page to return the actual page structures. There are very few actual users of these functions, so it is simple to standardize their usage. Since this is basic cleanup, I am submitting these changes as a standalone patch. Per Hugh Dickins' comments about it, I am also changing the pxx_page_kernel macros to pxx_page_vaddr to clarify their meaning.

Ulrich Weigand found a bug with the current version of the asm-powerpc/ptrace.h that prevents building at least the SPU target version of gdb, since some ptrace opcodes are not defined. The problem seems to have originated in the merging of 32 and 64 bit versions of that file, the problem is that some opcodes are only valid on 64 bit kernels, but are also used by 32 bit programs, so they can't depends on the __powerpc64__ symbol.

2006-09-21POWERPC: Get rid of remapping the whole immrVitaly Bordug
The stuff below cleans up the code attempting to remap the whole cpm2_immr early, as well as places happily assuming that fact. This is more like the 2.4 legacy stuff, and is at least confusing and unclear now. To keep the world comfortable, a new mechanism is introduced: before accessing specific immr register/register set, one needs to map it, using cpm2_map(<reg>), for instance, access to CPM command register will look like volatile cpm_cpm2_t *cp = cpm2_map(im_cpm); keeping the code clear, yet without "already defined somewhere" cpm2_immr. So far, unmapping code is not implemented, but it's not a big deal to add it, if the whole idea makes sense. Signed-off-by: Vitaly Bordug <vbordug@ru.mvista.com>

2006-09-13[POWERPC] Fix MMIO ops to provide expected barrier behaviourPaul Mackerras
This changes the writeX family of functions to have a sync instruction before the MMIO store rather than after, because the generally expected behaviour is that the device receiving the MMIO store can be guaranteed to see the effects of any preceding writes to normal memory. To preserve ordering between writeX and readX, and to preserve ordering between preceding stores and the readX, the readX family of functions have had an sync added before the load. Although writeX followed by spin_unlock is not officially guaranteed to keep the writeX inside the spin-locked region unless an mmiowb() is used, there are currently drivers that depend on the previous behaviour on powerpc, which was that the mmiowb wasn't actually required. Therefore we have a per-cpu flag that is set by writeX, cleared by __raw_spin_lock and mmiowb, and tested by __raw_spin_unlock. If it is set, __raw_spin_unlock does a sync and clears it. This changes both 32-bit and 64-bit readX/writeX. 32-bit already has a sync in __raw_spin_unlock (since lwsync doesn't exist on 32-bit), and thus doesn't need the per-cpu flag.

In the case of 64K page size, second PT_LOAD segments starts at 32K and the first one is not page aligned. __ioremap() (crash_dump.c) fails if pfn = 0 which is the case for the second PT_LOAD segment.

This fixes a problem introduced in 5db9fa9593e2ff69f2b95f9d59229dc4faaa564d. The last_jiffy per-cpu variable is only 32 bits on 32-bit machines, but it was being compared with a 64-bit quantity (tb_next_jiffy), which resulted in time not advancing. This fixes it by changing last_jiffy to be 64 bits on all platforms. With this, we no longer need tb_last_stamp as a 32-bit version of tb_last_jiffy, so this gets rid of tb_last_stamp and we just use tb_last_jiffy instead. This also fixes a bug when the boot cpu is not online, because using tb_last_stamp could have caused the wrong timebase origin value to be used when calculating the time of day.

This adds a new hardware information table for mpic. This enables the mpic code to deal with mpic controllers with different register layouts and hardware behaviours. This introduces CONFIG_MPIC_WEIRD. For boards with non standard mpic controllers, select CONFIG_MPIC_WEIRD and add its hardware information in the mpic_infos[] array. TSI108/109 PIC takes the first index of weird hardware information table. :) The table can be extended. The Tsi108/109 PIC looks like standard OpenPIC but, in fact, is different in register mapping and behavior. The patch does not affect the behavior of standard mpic. If CONFIG_MPIC_WEIRD is not defined, the code is essentially identical to the current code.
