* [SPARC64]: Fix of_iounmap() region release.David S. Miller2006-12-31

* [PATCH] Optimize D-cache alias handling on forkRalf Baechle2006-12-13
| | | | | | | | | | | Virtually index, physically tagged cache architectures can get away without cache flushing when forking. This patch adds a new cache flushing function flush_cache_dup_mm(struct mm_struct *) which for the moment I've implemented to do the same thing on all architectures except on MIPS where it's a no-op.

* [SPARC64]: Fix several kprobes bugs.David S. Miller2006-12-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - relbranch_fixup(), for non-branches, would end up setting regs->tnpc incorrectly, in fact it would set it equal to regs->tpc which would cause that instruction to execute twice Also, if this is not a PC-relative branch, we should just leave regs->tnpc as-is. This covers cases like 'jmpl' which branch to absolute values. - To be absolutely %100 safe, we need to flush the instruction cache for all assignments to kprobe->ainsn.insn[], including cases like add_aggr_kprobe() - prev_kprobe's status field needs to be 'unsigned long' to match the type of the value it is saving - jprobes were totally broken: = jprobe_return() can run in the stack frame of the jprobe handler, or in an even deeper stack frame, thus we'll be in the wrong register window than the one from the original probe state. So unwind using 'restore' instructions, if necessary, right before we do the jprobe_return() breakpoint trap. = There is no reason to save/restore the register window saved at %sp at jprobe trigger time. Those registers cannot be modified by the jprobe handler. Also, this code was saving and restoring "sizeof (struct sparc_stackf)" bytes. Depending upon the caller, this could clobber unrelated stack frame pieces if there is only a basic 128-byte register window stored on the stack, without the argument save area. So just saving and restoring struct pt_regs is sufficient. = Kill the "jprobe_saved_esp", totally unused. Also, delete "jprobe_saved_regs_location", with the stack frame unwind now done explicitly by jprobe_return(), this check is superfluous. Signed-off-by: David S. Miller <davem@davemloft.net>

* [PATCH] tty: preparatory structures for termios revampAlan Cox2006-12-08
| | | | | | | | | | | | | | | | | | | | In order to sort out our struct termios and add proper speed control we need to separate the kernel and user termios structures. Glibc is fine but the other libraries rely on the kernel exported struct termios and we need to extend this without breaking the ABI/API To do so we add a struct ktermios which is the kernel view of a termios structure and overlaps the struct termios with extra fields on the end for now. (That limitation will go away in later patches). Some platforms (eg alpha) planned ahead and thus use the same struct for both, others did not. This just adds the structures but does not use them, it seems a sensible splitting point for bisect if there are compile failures (not that I expect them) Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

* [PATCH] Directed yield: cpu_relax variants for spinlocks and rw-locksMartin Schwidefsky2006-10-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* [PATCH] Standardize pxx_page macrosDave McCracken2006-09-26
| | | | | | | | | | | | | | | | | | | | | 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.
