2007-09-10[MIPS] Provide empty irq_enable_hazard definition for legacy and R1 cores.Ralf Baechle
Following a strict interpretation the empty definition of irq_enable_hazard has always been a bug - but an intentional one because it didn't bite. This has now changed, for uniprocessor kernels mm/slab.c:do_drain() [...] on_each_cpu(do_drain, cachep, 1, 1); check_irq_on(); [...] may be compiled into a mtc0 c0_status; mfc0 c0_status sequence resulting in a back-to-back hazard.

New arch macro STACK_TOP_MAX it gives the larges valid stack address for the architecture in question. It differs from STACK_TOP in that it will not distinguish between personalities but will always return the largest possible address.

2007-07-18zs: move to the serial subsystemMaciej W. Rozycki
This is a reimplementation of the zs driver for the serial subsystem. Any resemblance to the old driver is purely coincidential. ;-) I do hope I got the handling of modem lines right -- better do not tackle me about the issue unless you feel too good... Any users of the old driver: please note the numbers of the serial lines have now been swapped, i.e. ttyS0 <-> ttyS1 and ttyS2 <-> ttyS3. It has to do with the modem lines mentioned above; basically the port A in a given chip has to be initialised before the port B if you want to use the latter as the serial console (which is usually the case), as operations on modem lines of the serial line associated with the port B access both ports (see the comment at the top of the driver for the details of wiring used). Please update your scripts. This is also the reason each SCC now requests an IRQ once only (as seen in "/proc/interrupts") -- the handler takes care of both ports at once as the line associated with the port B has to take status update interrupts from both ports (and yet the line of the port A takes its own for itself too). The old driver never got it right... Signed-off-by: Maciej W.

2007-07-17sb1250-duart.c: SB1250 DUART serial supportMaciej W. Rozycki
This is a driver for the SB1250 DUART, a dual serial port implementation included in the Broadcom family of SOCs descending from the SiByte SB1250 MIPS64 chip multiprocessor. It is a new implementation replacing the old-fashioned driver currently present in the linux-mips.org tree. It supports all the usual features one would expect from a(n asynchronous) serial driver, including modem line control (as far as hardware supports it -- there is edge detection logic missing from the DCD and RI lines and the driver does not implement polling of these lines at the moment), the serial console, BREAK transmission and reception, including the magic SysRq. The receive FIFO threshold is not maintained though. The driver was tested with a SWARM board which uses a BCM1250 SOC (which is dual MIPS64 CMP) and has both ports of the single DUART implemented wired externally. Both were tested. Testing included using the ports as terminal lines at 1200bps (which is the ports minimum), 115200bps and a couple of random speeds inbetween. The modem lines were verified to operate correctly. No testing was performed with a use as a network interface, like with SLIP or PPP. Signed-off-by: Maciej W.

2007-07-16Introduce compat_u64 and compat_s64 typesArnd Bergmann
One common problem with 32 bit system call and ioctl emulation is the different alignment rules between i386 and 64 bit machines. A number of drivers work around this by marking the compat structures as 'attribute((packed))', which is not the right solution because it breaks all the non-x86 architectures that want to use the same compat code. Hopefully, this patch improves the situation, it introduces two new types, compat_u64 and compat_s64. These are defined on all architectures to have the same size and alignment as the 32 bit version of u64 and s64. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Acked-by: David S.
