2008-07-23i386 syscall audit fast-pathRoland McGrath
This adds fast paths for 32-bit syscall entry and exit when TIF_SYSCALL_AUDIT is set, but no other kind of syscall tracing. These paths does not need to save and restore all registers as the general case of tracing does. Avoiding the iret return path when syscall audit is enabled helps performance a lot.

2008-07-23x86_64: remove bogus optimization in sysret_signalRoland McGrath
This short-circuit path in sysret_signal looks wrong to me. AFAICT, in practice the branch is never taken--and if it were, it would go wrong. To wit, try loading a module whose init function does set_thread_flag(TIF_IRET), and see insmod crash (presumably with a wrong user stack pointer). This is because the FIXUP_TOP_OF_STACK work hasn't been done yet when we jump around the call to ptregscall_common and get to int_with_check--where it expects the user RSP,SS,CS and EFLAGS to have been stored by FIXUP_TOP_OF_STACK. I don't think it's normally possible to get to sysret_signal with no _TIF_DO_NOTIFY_MASK bits set anyway, so these two instructions are already superfluous. If it ever did happen, it is harmless to call do_notify_resume with nothing for it to do. Signed-off-by: Roland McGrath <roland@redhat.com>

* Add struct ide_host which keeps pointers to host's ports. * Add ide_host_alloc[_all]() and ide_host_remove() helpers. * Pass 'struct ide_host *host' instead of 'u8 *idx' to ide_device_add[_all]() and rename it to ide_host_register[_all](). * Convert host drivers and core code to use struct ide_host. * Remove no longer needed ide_find_port(). * Make ide_find_port_slot() static. * Unexport ide_unregister(). v2: * Add missing 'struct ide_host *host' to macide.c. v3: * Fix build problem in pmac.c (s/ide_alloc_host/ide_host_alloc/) (Noticed by Stephen Rothwell).

2008-07-23ide: add struct ide_tp_ops (take 2)Bartlomiej Zolnierkiewicz
* Add struct ide_tp_ops for transport methods. * Add 'const struct ide_tp_ops *tp_ops' to struct ide_port_info and ide_hwif_t. * Set the default hwif->tp_ops in ide_init_port_data(). * Set host driver specific hwif->tp_ops in ide_init_port(). * Export ide_exec_command(), ide_read_status(), ide_read_altstatus(), ide_read_sff_dma_status(), ide_set_irq(), ide_tf_{load,read}() and ata_{in,out}put_data(). * Convert host drivers and core code to use struct ide_tp_ops. * Remove no longer needed default_hwif_transport(). * Cleanup ide_hwif_t from methods that are now in struct ide_tp_ops. While at it: * Use struct ide_port_info in falconide.c and q40ide.c. * Rename ata_{in,out}put_data() to ide_{in,out}put_data(). v2: * Fix missing convertion in ns87415.c. There should be no functional changes caused by this patch. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
2008-07-23ide: add 'config' field to hw_regs_tBartlomiej Zolnierkiewicz
Add 'config' field to hw_regs_t and use it to set hwif->config_data in ide_init_port_hw(), then convert ide_legacy_init_one() to use hw->config. There should be no functional changes caused by this patch. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
