2007-10-16x86: optimize page faults like all other achitectures and kill notifier cruftChristoph Hellwig
x86(-64) are the last architectures still using the page fault notifier cruft for the kprobes page fault hook. This patch converts them to the proper direct calls, and removes the now unused pagefault notifier bits aswell as the cruft in kprobes.c that was related to this mess. I know Andi didn't really like this, but all other architecture maintainers agreed the direct calls are much better and besides the obvious cruft removal a common way of dealing with kprobes across architectures is important aswell.

2007-10-16x86: Convert cpu_core_map to be a per cpu variableMike Travis
This is from an earlier message from 'Christoph Lameter': cpu_core_map is currently an array defined using NR_CPUS. This means that we overallocate since we will rarely really use maximum configured cpu. If we put the cpu_core_map into the per cpu area then it will be allocated for each processor as it comes online. This means that the core map cannot be accessed until the per cpu area has been allocated. Xen does a weird thing here looping over all processors and zeroing the masks that are not yet allocated and that will be zeroed when they are allocated. I commented the code out.

2007-10-16wake up from a serial portGuennadi Liakhovetski
Enable wakeup from serial ports, make it run-time configurable over sysfs, e.g., echo enabled > /sys/devices/platform/serial8250.0/tty/ttyS0/power/wakeup Requires # CONFIG_SYSFS_DEPRECATED is not set Following suggestions from Alan and Russell moved the may_wake_up checks to serial_core.c. This time actually tested - it does even work. Could someone, please, verify, that put_device after device_find_child is correct? Also would be nice to test with a Natsemi UART, that can wake up the system, if such systems exist. For this you just have to apply the patch below, issue the above "echo" command to one of your Natsemi port, suspend and resume your system, and verify that your Natsemi port still works. If you are actually capable of waking up the system from that port, would be nice to test that as well.

2007-10-16slow down printk during bootRandy Dunlap
Optionally add a boot delay after each kernel printk() call, crudely measured in milliseconds, with a maximum delay of 10 seconds per printk. Enable CONFIG_BOOT_PRINTK_DELAY=y and then add (e.g.): "lpj=loops_per_jiffy boot_delay=100" to the kernel command line. It has been useful in cases like "during boot, my machine just reboots or the screen goes black" by slowing down printk, (and adding initcall_debug), we can usually see the last thing that happened before the lights went out which is usually a valuable clue.

2007-10-15[INET]: Consolidate the xxx_frag_destroyPavel Emelyanov
To make in possible we need to know the exact frag queue size for inet_frags->mem management and two callbacks: * to destoy the skb (optional, used in conntracks only) * to free the queue itself (mandatory, but later I plan to move the allocation and the destruction of frag_queues into the common place, so this callback will most likely be optional too).

2007-10-15[INET]: Collect common frag sysctl variables togetherPavel Emelyanov
Some sysctl variables are used to tune the frag queues management and it will be useful to work with them in a common way in the future, so move them into one structure, moreover they are the same for all the frag management codes. I don't place them in the existing inet_frags object, introduced in the previous patch for two reasons: 1. to keep them in the __read_mostly section; 2. not to export the whole inet_frags objects outside.

2007-10-15[INET]: Collect frag queues management objects togetherPavel Emelyanov
There are some objects that are common in all the places which are used to keep track of frag queues, they are: * hash table * LRU list * rw lock * rnd number for hash function * the number of queues * the amount of memory occupied by queues * secret timer Move all this stuff into one structure (struct inet_frags) to make it possible use them uniformly in the future. Like with the previous patch this mostly consists of hunks like - write_lock(&ipfrag_lock); + write_lock(&ip4_frags.lock); To address the issue with exporting the number of queues and the amount of memory occupied by queues outside the .c file they are declared in, I introduce a couple of helpers.

2007-10-15Add dcr_host_t.base in dcr_read()/dcr_write()Michael Ellerman
Now that all users of dcr_read()/dcr_write() add the dcr_host_t.base, we can save them the trouble and do it in dcr_read()/dcr_write(). As some background to why we just went through all this jiggery-pokery, benh sayeth: Initially the goal of the dcr_read/dcr_write routines was to operate like mfdcr/mtdcr which take absolute DCR numbers. The reason is that on 4xx hardware, indirect DCR access is a pain (goes through a table of instructions) and it's useful to have the compiler resolve an absolute DCR inline. We decided that wasn't worth the API bastardisation since most places where absolute DCR values are used are low level 4xx-only code which may as well continue using mfdcr/mtdcr, while the new API is designed for device "instances" that can exist on 4xx and Axon type platforms and may be located at variable DCR offsets.

2007-10-15[ARM] pxa: Avoid pxa_gpio_mode() in gpio_direction_{in,out}put()Russell King
pxa_gpio_mode() is a universal call that fiddles with the GAFR (gpio alternate function register.) GAFR does not exist on PXA3 CPUs, but instead the alternate functions are controlled via the MFP support code. Platforms are expected to configure the MFP according to their needs in their platform support code rather than drivers. We extend this idea to the GAFR, and make the gpio_direction_*() functions purely operate on the GPIO level. This means platform support code is entirely responsible for configuring the GPIOs alternate functions on all PXA CPU types. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
