2007-07-16fix jvc cdrom drive lockupZhang, Yanmin1-0/+12
Before calling init_hwif_default, ide_unregister gets lock ide_lock and disables irq. init_hwif_default calls ide_default_io_base which calls pci_get_device and later pci_get_subsys tries to apply for semaphore pci_bus_sem and goes to sleep. Mostly, pci_get_device should be called when irq is turned on. ide_default_io_base just needs find if list pci_devices is empty.

2007-07-16serial: convert early_uart to earlycon for 8250Yinghai Lu4-81/+84
Beacuse SERIAL_PORT_DFNS is removed from include/asm-i386/serial.h and include/asm-x86_64/serial.h. the serial8250_ports need to be probed late in serial initializing stage. the console_init=>serial8250_console_init=> register_console=>serial8250_console_setup will return -ENDEV, and console ttyS0 can not be enabled at that time. need to wait till uart_add_one_port in drivers/serial/serial_core.c to call register_console to get console ttyS0. that is too late. Make early_uart to use early_param, so uart console can be used earlier. Make it to be bootconsole with CON_BOOT flag, so can use console handover feature. and it will switch to corresponding normal serial console automatically. new command line will be: console=uart8250,io,0x3f8,9600n8 console=uart8250,mmio,0xff5e0000,115200n8 or earlycon=uart8250,io,0x3f8,9600n8 earlycon=uart8250,mmio,0xff5e0000,115200n8 it will print in very early stage: Early serial console at I/O port 0x3f8 (options '9600n8') console [uart0] enabled later for console it will print: console handover: boot [uart0] -> real [ttyS0] Signed-off-by: <yinghai.lu@sun.com> Cc: Andi Kleen <ak@suse.de> Cc: Bjorn Helgaas <bjorn.helgaas@hp.com> Cc: Russell King <rmk@arm.linux.org.uk> Cc: Gerd Hoffmann <kraxel@suse.de> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2007-07-16serial: assert DTR for serial console devicesYinghai Lu1-0/+6
Some RS-232 devices require DTR to be asserted before they can be used. DTR is normally asserted in uart_startup() when the port is opened. But we don't actually open serial console ports, so assert DTR when the port is added. BTW: earlyprintk and early_uart are hard coded to set DTR/RTS. rmk says The only issue I can think of is the possibility for an attached modem to auto-answer or maybe even auto-dial before the system is ready for it to do so. Might have an undesirable cost implication for some running with such a setup. Apart from that, I can't think of any other side effect of this specific patch.

2007-07-16[SPARC64]: Abstract out mdesc accesses for better MD update handling.David S. Miller2-24/+34
Since we have to be able to handle MD updates, having an in-tree set of data structures representing the MD objects actually makes things more painful. The MD itself is easy to parse, and we can implement the existing interfaces using direct parsing of the MD binary image. The MD is now reference counted, so accesses have to now take the form: handle = mdesc_grab(); ... operations on MD ... mdesc_release(handle); The only remaining issue are cases where code holds on to references to MD property values. mdesc_get_property() returns a direct pointer to the property value, most cases just pull in the information they need and discard the pointer, but there are few that use the pointer directly over a long lifetime. Those will be fixed up in a subsequent changeset. A preliminary handler for MD update events from domain services is there, it is rudimentry but it works and handles all of the reference counting. It does not check the generation number of the MDs, and it does not generate a "add/delete" list for notification to interesting parties about MD changes but that will be forthcoming.
