* cciss: Fix pci_driver.shutdown while device is still activeGerald Britton2007-05-19
| | | | | | | | | | | | | | | | | Fix an Oops in the cciss driver caused by system shutdown while a filesystem on a cciss device is still active. The cciss_remove_one function only properly removes the device if the device has been cleanly released by its users, which is not the case when the pci_driver.shutdown method is called. This patch adds a new cciss_shutdown function to better match the pattern used by various SCSI drivers: deactivate device interrupts and flush caches. It also alters the cciss_remove_one function to match and readds the __devexit annotation that was removed when cciss_remove_one was serving as the pci_driver.shutdown method.

* Further update of the i386 boot documentationH. Peter Anvin2007-05-18
| | | | | | | | | | | A number of items in the i386 boot documentation have been either vague, outdated or hard to read. This text revision adds several more examples, including a memory map for a modern kernel load. It also adds a field-by-field detailed description of the setup header, and a bootloader ID for Qemu.

| | | | | | | | | | | | | | | | | | 1 is a power of two, therefore roundup_pow_of_two(1) should return 1. It does in case the argument is a variable but in case it's a constant it behaves wrong and returns 0. Probably nobody ever did it so this was never noticed.

This does require a very small code change to locate the busses to be probed for of_platform devices by 'compatible' instead of 'device_type'. - A node is added for the SRAM controller - The unit address of the small-flash node is adjusted to correctly reflect the reg property. - device_type values for the MAL and ZMII are updated to reflected more up-to-date versions of the binding. - An incorrect offset in the partition map for the large-flash node is corrected. - Some redundant values, already commented out are removed entirely.

| * | [POWERPC] Fix IO space on PCI buses created from of_platformBenjamin Herrenschmidt2007-05-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This changes the way of_platform_pci creates PCI host bridges such that it uses request_phb_iospace() for mapping the IO ports, instead of using the dynamic hotplug stuff. That guarantees the IO space stays within the 2GB limit and thus doesn't break half of the legacy drivers around. Fixes a couple of warnings due to missing IO space while at it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ft_set_prop() from flatdevtree.c in the zImage wrapper will either replace an existing property in the flat device tree, or add a new property definiion if the given property isn't present. However, when adding properties, it adds the property definition immediately before the node's END_NODE tag, potentially after any subnode definitions for the node. This confuses the kernel flat tree parser in prom.c which assumes that all property definitions for a node come before all subnode definitions. This patch corrects ft_set_prop() so that it adds new properties before the first subnode, instead of before the END_NODE tag.

| * | [POWERPC] Remove fixup_bigphys_addr() for arch/powerpc to avoid link errorDavid Gibson2007-05-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are no actual implementations of fixup_bigphys_addr() in arch/powerpc, and with a 64-bit aware ioremap() and so forth, it should no longer be necessary. This patch removes the last dregs of fixup_bigphys_addr() from arch/powerpc. In fact, the only reason this hasn't caused link errors already is that nobody must have tried using one of the small number of drivers using io_remap_pfn_range() on one of the small number of platforms which are 32-bit but define CONFIG_PHYS_64BIT.

| * | | [BLUETOOTH]: Fix locking in hci_sock_dev_event().Satyam Sharma2007-05-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We presently use lock_sock() to acquire a lock on a socket in hci_sock_dev_event(), but this goes BUG because lock_sock() can sleep and we're already holding a read-write spinlock at that point. So, we must use the non-sleeping BH version, bh_lock_sock(). However, hci_sock_dev_event() is called from user context and hence using simply bh_lock_sock() will deadlock against a concurrent softirq that tries to acquire a lock on the same socket. Hence, disabling BH's before acquiring the socket lock and enable them afterwards, is the proper solution to fix socket locking in hci_sock_dev_event().
