Stop the HFSPLUS filesystem from using iget() and read_inode(). Replace hfsplus_read_inode() with hfsplus_iget(), and call that instead of iget(). hfsplus_iget() then uses iget_locked() directly and returns a proper error code instead of an inode in the event of an error. hfsplus_fill_super() returns any error incurred when getting the root inode.

This patchset is for the vmcoreinfo data. The vmcoreinfo data has the minimum debugging information only for dump filtering. makedumpfile (dump filtering command) gets it to distinguish unnecessary pages, and makedumpfile creates a small dumpfile. This patch: VMCOREINFO_SIZE() should be renamed VMCOREINFO_STRUCT_SIZE() since it's always returning the size of the struct with a given name. This change would allow VMCOREINFO_TYPEDEF_SIZE() to simply become VMCOREINFO_SIZE() since it need not be used exclusively for typedefs.

This patchset adds a flags variable to reserve_bootmem() and uses the BOOTMEM_EXCLUSIVE flag in crashkernel reservation code to detect collisions between crashkernel area and already used memory. This patch: Change the reserve_bootmem() function to accept a new flag BOOTMEM_EXCLUSIVE. If that flag is set, the function returns with -EBUSY if the memory already has been reserved in the past. This is to avoid conflicts. Because that code runs before SMP initialisation, there's no race condition inside reserve_bootmem_core().

This is a set of changes to implement proper resource management in the driver, including iomem space reservation and operating on physical addresses ioremap()ped appropriately using accessory functions rather than unportable direct assignments. Some adjustments to code are made to reflect the architecture of the interface, which is a centrally controlled multiport (or, as referred to from DEC documentation, a serial line multiplexer, going up to 8 lines originally) rather than a bundle of separate ports. Types are changed, where applicable, to specify the width of hardware registers explicitly. The interrupt handler is now managed in the ->startup() and ->shutdown() calls for consistency with other drivers and also in preparation to handle the handover from the initial firmware-based console gracefully.

Replace all casts from "struct uart_port *" to "struct dz_port *" with a construct based on container_of(). This makes the conversion work irrespective of where the former struct is located within the latter. By popular request I have implemented it as an inline function rather than a macro this time.

A set of changes to the way termios settings are propagated to the serial port hardware. The DZ11 only supports a selection of fixed baud settings, so some requests may not be fulfilled. Keep the old setting in such a case and failing that resort to 9600bps. Also add a missing update of the transmit timeout. And remove the explicit encoding of the line selected from writes to the Line Parameters Register as it has been preencoded by the ->set_termios() call already. Finally, remove a duplicate macro for the Receiver Enable bit. Signed-off-by:

Reformat the Kconfig entries and update descriptions for accuracy. Select the driver by default for configurations of interest. For the curious: 32BIT means only 32-bit DECstations support the device, not that the driver is not 64-bit clean; I have not checked that either though. Signed-off-by:

Well, panic() is a little bit undue if request_irq() fails; there is probably no need to justify it any further. Handle the case gracefully, by unregistering the driver. Signed-off-by:

Polled transmission is tricky enough with the DZ11 design. While "loop" is set to a high value, conceptually you are not allowed to transmit without checking whether the device offers the right transmission line (yes, it is the device that selects the line -- the driver has no control over it other than disabling the transmitter offered if it is the wrong one), so the loop has to be run at least once. Well, the '1977 or PDP11 view of how serial lines should be handled... Except that the serial interface used to be quite an impressive board back then rather than chip. Signed-off-by:
