2006-10-05[PA-RISC] Fix must_check warnings in drivers.cMatthew Wilcox
Panic if we can't register the parisc bus or the root parisc device. There's no way we can boot without them, so let the user know ASAP. If we can't register a parisc device, handle the failure gracefully. Signed-off-by: Matthew Wilcox <willy@parisc-linux.org>

2006-10-04[PATCH] atmel_serial: Fix roundoff error in atmel_console_get_optionsHaavard Skinnemoen
The atmel_console_get_options() function initializes the baud, parity and bits settings from the actual hardware setup, in case it has been initialized by a e.g. boot loader. The baud rate, however, is not necessarily exactly equal to one of the standard baud rates (115200, etc.) This means that the baud rate calculated by this function may be slightly higher or slightly lower than one of the standard baud rates. If the baud rate is slightly lower than the target, this causes problems when uart_set_option() tries to match the detected baud rate against the standard baud rate, as it will always select a baud rate that is lower or equal to the target rate. For example if the detected baud rate is slightly lower than 115200, usart_set_options() will select 57600. This patch fixes the problem by subtracting 1 from the value in BRGR when calculating the baud rate. The detected baud rate will thus always be higher than the nearest standard baud rate, and uart_set_options() will end up doing the right thing. Tested on ATSTK1000 and AT91RM9200-EK boards. Both are broken without this patch. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com> Acked-by: Andrew Victor <andrew@sanpeople.com> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2006-10-04[PATCH] AVR32: Allow renumbering of serial devicesHaavard Skinnemoen
Allow the board to remap actual USART peripheral devices to serial devices by calling at32_map_usart(hw_id, serial_line). This ensures that even though ATSTK1002 uses USART1 as the first serial port, it will still have a ttyS0 device. This also adds a board-specific early setup hook and moves the at32_setup_serial_console() call there from the platform code.

2006-10-04[PATCH] atmel_serial: Pass fixed register mappings through platform_dataHaavard Skinnemoen
In order to initialize the serial console early, the atmel_serial driver had to do a hack where it compared the physical address of the port with an address known to be permanently mapped, and used it as a virtual address. This got around the limitation that ioremap() isn't always available when the console is being initalized. This patch removes that hack and replaces it with a new "regs" field in struct atmel_uart_data that the board-specific code can initialize to a fixed virtual mapping for platform devices where this is possible. It also initializes the DBGU's regs field with the address the driver used to check against. On AVR32, the "regs" field is initialized from the physical base address when this it can be accessed through a permanently 1:1 mapped segment, i.e. the P4 segment. If regs is NULL, the console initialization is delayed until the "real" driver is up and running and ioremap() can be used.

2006-10-04[PATCH] rcu: simplify/improve batch tuningOleg Nesterov
Kill a hard-to-calculate 'rsinterval' boot parameter and per-cpu rcu_data.last_rs_qlen. Instead, it adds adds a flag rcu_ctrlblk.signaled, which records the fact that one of CPUs has sent a resched IPI since the last rcu_start_batch(). Roughly speaking, we need two rcu_start_batch()s in order to move callbacks from ->nxtlist to ->donelist. This means that when ->qlen exceeds qhimark and continues to grow, we should send a resched IPI, and then do it again after we gone through a quiescent state. On the other hand, if it was already sent, we don't need to do it again when another CPU detects overflow of the queue. Signed-off-by: Oleg Nesterov <oleg@tv-sign.ru> Acked-by: Paul E.
