2007-02-11[PATCH] consolidate line discipline number definitionsTilman Schmidt
The line discipline numbers N_* are currently defined for each architecture individually, but (except for a seeming mistake) identically, in asm/termios.h. There is no obvious reason why these numbers should be architecture specific, nor any apparent relationship with the termios structure. The total number of these, NR_LDISCS, is defined in linux/tty.h anyway. So I propose the following patch which moves the definitions of the individual line disciplines to linux/tty.h too. Three of these numbers (N_MASC, N_PROFIBUS_FDL, and N_SMSBLOCK) are unused in the current kernel, but the patch still keeps the complete set in case there are plans to use them yet.

2007-02-10[SPARC64]: Add PCI MSI support on Niagara.David S. Miller
This is kind of hokey, we could use the hardware provided facilities much better. MSIs are assosciated with MSI Queues. MSI Queues generate interrupts when any MSI assosciated with it is signalled. This suggests a two-tiered IRQ dispatch scheme: MSI Queue interrupt --> queue interrupt handler MSI dispatch --> driver interrupt handler But we just get one-level under Linux currently. What I'd like to do is possibly stick the IRQ actions into a per-MSI-Queue data structure, and dispatch them form there, but the generic IRQ layer doesn't provide a way to do that right now. So, the current kludge is to "ACK" the interrupt by processing the MSI Queue data structures and ACK'ing them, then we run the actual handler like normal. We are wasting a lot of useful information, for example the MSI data and address are provided with ever MSI, as well as a system tick if available. If we could pass this into the IRQ handler it could help with certain things, in particular for PCI-Express error messages. The MSI entries on sparc64 also tell you exactly which bus/device/fn sent the MSI, which would be great for error handling when no registered IRQ handler can service the interrupt. We override the disable/enable IRQ chip methods in sun4v_msi, so we have to call {mask,unmask}_msi_irq() directly from there. This is another ugly wart. Signed-off-by: David S. Miller <davem@davemloft.net>

2006-12-10[SPARC64]: Fix several kprobes bugs.David S. Miller
- 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>

2006-12-08[PATCH] tty: preparatory structures for termios revampAlan Cox
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>

2006-12-01PCI: Use pci_generic_prep_mwi on sparc64Matthew Wilcox
The setting of the CACHE_LINE_SIZE register in sparc64's pci initialisation code isn't quite adequate as the device may have incompatible requirements. The generic code tests for this, so switch sparc64 over to using it. Since sparc64 has different L1 cache line size and PCI cache line size, it would need to override the generic code like i386 and ia64 do. We know what the cache line size is at compile time though, so introduce a new optional constant PCI_CACHE_LINE_BYTES.

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.

This prevents cross-region mappings on IA64 and SPARC which could lead to system crash. They were correctly trapped for normal mmap() calls, but not for the kernel internal calls generated by executable loading. This code just moves the architecture-specific cross-region checks into an arch-specific "arch_mmap_check()" macro, and defines that for the architectures that needed it (ia64, sparc and sparc64). Architectures that don't have any special requirements can just ignore the new cross-region check, since the mmap() code will just notice on its own when the macro isn't defined.
