|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove TTY_DONT_FLIP tty flag. This flag was introduced in 2.1.X kernels to prevent the N_TTY line discipline functions read_chan() and n_tty_receive_buf() from running at the same time. 2.2.15 introduced tty->read_lock to protect access to the N_TTY read buffer, which is the only state requiring protection between these two functions. The current TTY_DONT_FLIP implementation is broken for SMP, and is not universally honored by drivers that send data directly to the line discipline receive_buf function. Because TTY_DONT_FLIP is not necessary, is broken in implementation, and is not universally honored, it is removed.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This ugly hack was long overdue to die. It was a way to print out Sparc interrupts in a more freindly format, since IRQ numbers were arbitrary opaque 32-bit integers which vectored into PIL levels. These 32-bit integers were not necessarily in the 0-->NR_IRQS range, but the PILs they vectored to were. The idea now is that we will increase NR_IRQS a little bit and use a virtual<-->real IRQ number mapping scheme similar to PowerPC. That makes this IRQ printing hack irrelevant, and furthermore only a handful of drivers actually used __irq_itoa() making it even less useful. Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A bug report from Gerd Hoffmann has highlighted that unconditionally enabling the transmit interrupt at the end of console writes is very bad. In Gerd's case, it causes the test for buggy UARTs to give false positives, incorrectly identifying ports as buggy when they are not. Moreover, if we unconditionally enable the interrupt, and the port is sharing it's interrupt with other ports, there is the very real possibility that we'll cause an interrupt storm. (Not all ports use OUT2 as an interrupt mask.) Hence, revert part of f91a3715db2bb44fcf08cec642e68f919b70f7f4 and all of f5968b37b3ad35b682b574b578843a0361218aff until a better solution can be found.

| * [SERIAL] 8250: set divisor register correctly for AMD Alchemy SoC uartJon Anders Haugum2006-04-30
| | | | | | | | | | | | | | | | | | | | | | Alchemy SoC uart have got a non-standard divisor register that needs some special handling. This patch adds divisor read/write functions with test and special handling for Alchemy internal uart.

| * [SERIAL] AMD Alchemy UART: claim memory rangeSergei Shtylyov2006-04-30
| | | | | | | | | | | | | | | | | | I've noticed that the 8250/Au1x00 driver (drivers/serial/8250_au1x00.c) doesn't claim UART memory ranges and uses wrong (KSEG1-based) UART addresses instead of the physical ones.

| * [SERIAL] Clean up serial locking when obtaining a reference to a portRussell King2006-04-30
| | | | | | | | | | | | | | | | | | | | | | | | | | The locking for the uart_port is over complicated, and can be simplified if we introduce a flag to indicate that a port is "dead" and will be removed. This also helps the validator because it removes a case of non-nested unlock ordering.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A number of small issues are fixed, and added the header file, missed from the original series. With this, driver should be pretty stable as tested among both platform-device-driven and "old way" boards. Also added missing GPL statement , and updated year field on existing ones to reflect code update.
