* avr32: Generic clockevents supportDavid Brownell2008-04-191-112/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This combines three patches from David Brownell: * avr32: tclib support * avr32: simplify clocksources * avr32: Turn count/compare into a oneshot clockevent device Register both TC blocks (instead of just the first one) so that the AT32/AT91 tclib code will pick them up (instead of just the avr32-only PIT-style clocksource). Rename the first one and its resources appropriately. More cleanups to the cycle counter clocksource code - Disable all the weak symbol magic; remove the AVR32-only TCB-based clocksource code (source and header). - Mark the __init code properly. - Don't forget to report IRQF_TIMER. - Make the system work properly with this clocksource, by preventing use of the CPU "idle" sleep state in the idle loop when it's used. Package the avr32 count/compare timekeeping support as a oneshot clockevent device, so it supports NO_HZ and high res timers. This means it also supports plugging in other clockevent devices and clocksources.

* avr32: pass i2c board info through at32_add_device_twiBen Nizette2008-04-191-1/+4
| | | | | | | | | | | | | | New-style I2C drivers require that motherboard-mounted I2C devices are registered with the I2C core, typically at arch_initcall time. This can be done nice and neat by passing the struct i2c_board_info[] through at32_add_device_twi just like we do for the SPI board info. While we've got the hood up, remove a duplicate declaration of at32_add_device_twi() in board.h.

* avr32: cleanup - use _AC macro to define PAGE_SIZECyrill Gorcunov2008-04-191-5/+3
| | | | | | | | | | | | PAGE_SIZE is used both from assembly and C code. We want to have type specifiers when using it from C, but this will make the assembler confused, so we need to make it conditional. This is exactly what the _AC macro is for, so using it allows us to get rid of a few lines of cpp noise.

Most AT91 and AT32 SOCs have one or two of these TC blocks, which include three 16-bit timers that can be interconnected in various ways. These TC blocks can be used for external interfacing (such as PWM and measurement), or used as somewhat quirky sixteen-bit timers. Changes relative to the original version: * Drop unneeded inclusion of <linux/mutex.h> * Support an arbitrary number of TC blocks * Return a struct with information about a TC block from atmel_tc_alloc() instead of using a combination of return values and "out" parameters. * ioremap() the I/O registers on allocation * Look up clocks and irqs for all channels * Add "name" parameter to atmel_tc_alloc() and use this when requesting the iomem resource. * Check if the platform provided the necessary resources at probe() time instead of when the TCB is allocated.

This is done to avoid LSM registration clashes in case of more than one bult-in module. User can choose a security module to enable at boot. If no security= boot parameter is specified, only the first LSM asking for registration will be loaded. An invalid security module name will be treated as if no module has been chosen. LSM modules must check now if they are allowed to register by calling security_module_enable(ops) first. Modify SELinux and SMACK to do so. Do not let SMACK register smackfs if it was not chosen on boot. Smackfs assumes that smack hooks are registered and the initial task security setup (swapper->security) is done.

| * | | | [NETNS]: The generic per-net pointers.Pavel Emelyanov2008-04-152-0/+51
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add the elastic array of void * pointer to the struct net. The access rules are simple: 1. register the ops with register_pernet_gen_device to get the id of your private pointer 2. call net_assign_generic() to put the private data on the struct net (most preferably this should be done in the ->init callback of the ops registered) 3. do not store any private reference on the net_generic array; 4. do not change this pointer while the net is alive; 5. use the net_generic() to get the pointer. When adding a new pointer, I copy the old array, replace it with a new one and schedule the old for kfree after an RCU grace period. Since the net_generic explores the net->gen array inside rcu read section and once set the net->gen->ptr[x] pointer never changes, this grants us a safe access to generic pointers. Quoting Paul: "... RCU is protecting -only- the net_generic structure that net_generic() is traversing, and the [pointer] returned by net_generic() is protected by a reference counter in the upper-level struct net."

| * | | | [NETNS]: The net-subsys IDs generator.Pavel Emelyanov2008-04-151-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To make some per-net generic pointers, we need some way to address them, i.e. - IDs. This is simple IDA-based IDs generator for pernet subsystems. Addressing questions about potential checkpoint/restart problems: these IDs are "lite-offsets" within the net structure and are by no means supposed to be exported to the userspace. Since it will be used in the nearest future by devices only (tun, vlan, tunnels, bridge, etc), I make it resemble the functionality of register_pernet_device(). The new ids is stored in the *id pointer _before_ calling the init callback to make this id available in this callback. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S.

This change eliminates the need for a mutex in the TIPC-specific portion of the socket protocol data structure -- in its place, the standard Linux socket backlog queue and associated locking routines are utilized. These changes fix a long-standing receive queue bug on SMP systems, and also enable individual read and write threads to utilize a socket without unnecessarily interfering with each other.
