2009-12-09sh: add a start_transfer() callback to the LCDC driverMagnus Damm1-0/+2
This patch adds a ->start_transfer() callback to the driver sh_mobile_lcdcfb.c. The callback is used to program the LCDC panel in the case of one-shot mode. Needed by the LCD controller used on the KFR2R09 board. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

This file breaks out the SuperH PFC code from arch/sh/kernel/gpio.c + arch/sh/include/asm/gpio.h to drivers/sh/pfc.c + include/linux/sh_pfc.h. Similar to the INTC stuff.

2009-11-17fcntl: rename F_OWNER_GID to F_OWNER_PGRPPeter Zijlstra1-1/+1
This is for consistency with various ioctl() operations that include the suffix "PGRP" in their names, and also for consistency with PRIO_PGRP, used with setpriority() and getpriority(). Also, using PGRP instead of GID avoids confusion with the common abbreviation of "group ID". I'm fine with anything that makes it more consistent, and if PGRP is what is the predominant abbreviation then I see no need to further confuse matters by adding a third one.

2009-11-17mm: allow memory hotplug and hibernation in the same kernelAndi Kleen1-2/+19
Allow memory hotplug and hibernation in the same kernel Memory hotplug and hibernation were exclusive in Kconfig. This is obviously a problem for distribution kernels who want to support both in the same image. After some discussions with Rafael and others the only problem is with parallel memory hotadd or removal while a hibernation operation is in process. It was also working for s390 before. This patch removes the Kconfig level exclusion, and simply makes the memory add / remove functions grab the pm_mutex to exclude against hibernation. Fixes a regression - old kernels didn't exclude memory hotadd and hibernation.

2009-11-13sctp: Set source addresses on the association before adding transportsVlad Yasevich1-1/+1
Recent commit 8da645e101a8c20c6073efda3c7cc74eec01b87f sctp: Get rid of an extra routing lookup when adding a transport introduced a regression in the connection setup. The behavior was different between IPv4 and IPv6. IPv4 case ended up working because the route lookup routing returned a NULL route, which triggered another route lookup later in the output patch that succeeded. In the IPv6 case, a valid route was returned for first call, but we could not find a valid source address at the time since the source addresses were not set on the association yet. Thus resulted in a hung connection. The solution is to set the source addresses on the association prior to adding peers.

2009-11-12fb: remove fb_save_state() and fb_restore_state operationsKrzysztof Helt1-6/+0
Remove fb_save_state() and fb_restore_state operations from frame buffer layer. They are used only in two drivers: 1. savagefb - and cause bug #11248 2. uvesafb Usage of these operations is misunderstood in both drivers so kill these operations, fix the bug #11248 and avoid confusion in the future. Tested on Savage 3D/MV card and the patch fixes the bug #11248. The frame buffer layer uses these funtions during switch between graphics and text mode of the console, but these drivers saves state before switching of the frame buffer (in the fb_open) and after releasing it (in the fb_release). This defeats the purpose of these operations.

2009-11-06netfilter: nf_nat: fix NAT issue in 2.6.30.4+Jozsef Kadlecsik2-5/+7
Vitezslav Samel discovered that since 2.6.30.4+ active FTP can not work over NAT. The "cause" of the problem was a fix of unacknowledged data detection with NAT (commit a3a9f79e361e864f0e9d75ebe2a0cb43d17c4272). However, actually, that fix uncovered a long standing bug in TCP conntrack: when NAT was enabled, we simply updated the max of the right edge of the segments we have seen (td_end), by the offset NAT produced with changing IP/port in the data. However, we did not update the other parameter (td_maxend) which is affected by the NAT offset. Thus that could drift away from the correct value and thus resulted breaking active FTP. The patch below fixes the issue by *not* updating the conntrack parameters from NAT, but instead taking into account the NAT offsets in conntrack in a consistent way. (Updating from NAT would be more harder and expensive because it'd need to re-calculate parameters we already calculated in conntrack.)

Commit 0c570cdeb8fdfcb354a3e9cd81bfc6a09c19de0c (PM / yenta: Fix cardbus suspend/resume regression) caused resume to fail on systems with two CardBus bridges. While the exact nature of the failure is not known at the moment, it can be worked around by splitting the yenta resume into an early part, executed during the early phase of resume, that will only resume the socket and power it up if there was a card in it during suspend, and a late part, executed during "regular" resume, that will carry out all of the remaining yenta resume operations.

2009-11-029p: fix readdir corner casesEric Van Hensbergen1-4/+3
The patch below also addresses a couple of other corner cases in readdir seen with a large (e.g. 64k) msize. I'm not sure what people think of my co-opting of fid->aux here. I'd be happy to rework if there's a better way. When the size of the user supplied buffer passed to readdir is smaller than the data returned in one go by the 9P read request, v9fs_dir_readdir() currently discards extra data so that, on the next call, a 9P read request will be issued with offset < previous offset + bytes returned, which voilates the constraint described in paragraph 3 of read(5) description. This patch preseves the leftover data in fid->aux for use in the next call. Signed-off-by: Jim Garlick <garlick@llnl.gov> Signed-off-by: Eric Van Hensbergen <ericvh@gmail.com>

Different CPUs will have different starting vectors, with varying amounts of reserved or unusable vector space prior to the first slot. This introduces a legacy vector reservation system that inserts itself in between the CPU vector map registration and the platform specific IRQ setup. This works fine in practice as the only new vectors that boards need to establish on their own should be dynamically allocated rather than arbitrarily assigned. As a plus, this also makes all of the converted platforms sparseirq ready. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2009-10-298250_pci: add IBM Saturn serial cardBenjamin Herrenschmidt1-0/+3
The IBM Saturn serial card has only one port. Without that fixup, the kernel thinks it has two, which confuses userland setup and admin tools as well.

2009-10-29strstrip(): mark as as must_checkKOSAKI Motohiro1-1/+1
strstrip() can return a modified value of its input argument, when removing elading whitesapce. So it is surely bug for this function's return value to be ignored. The caller is probably going to use the incorrect original pointer. So mark it __must_check to prevent this frm happening (as it has before).

2009-10-29cpufreq: add cpufreq_get() stub for CONFIG_CPU_FREQ=nRandy Dunlap1-0/+7
When CONFIG_CPU_FREQ is disabled, cpufreq_get() needs a stub. Used by kvm (although it looks like a bit of the kvm code could be omitted when CONFIG_CPU_FREQ is disabled). arch/x86/built-in.o: In function `kvm_arch_init': (.text+0x10de7): undefined reference to `cpufreq_get' (Needed in linux-next's KVM tree, but it's correct in 2.6.32).

2009-10-29param: fix lots of bugs with writing charp params from sysfs, by leaking mem.Rusty Russell1-1/+0
e180a6b7759a "param: fix charp parameters set via sysfs" fixed the case where charp parameters written via sysfs were freed, leaving drivers accessing random memory. Unfortunately, storing a flag in the kparam struct was a bad idea: it's rodata so setting it causes an oops on some archs. But that's not all: 1) module_param_array() on charp doesn't work reliably, since we use an uninitialized temporary struct kernel_param. 2) there's a fundamental race if a module uses this parameter and then it's changed: they will still access the old, freed, memory. The simplest fix (ie. for 2.6.32) is to never free the memory. This prevents all these problems, at cost of a memory leak. In practice, there are only 18 places where a charp is writable via sysfs, and all are root-only writable.
