* [PATCH] VIA VT8235 PCI quirkIvan Kokshaysky2005-08-081-0/+19
| | | | | | | | | | | | | Like many other southbridges from different manufacturers, VIA VT8235 chip has two non-standard BARs for power management and SMBus registers (see the datasheet at http://www.via.com.tw). This new quirk routine fixes boot problem with 2.6.13-rc2/rc6 kernels on Targa Visionary 811 Athlon64 laptop, as reported by Mikael Pettersson <mikpe@csd.uu.se>.

* [PATCH] nvidiafb: Fix initial display corruption on certain laptopsAntonino Daplas2005-08-082-0/+12
| | | | | | | | | | | | | | | | | | | | | | | Reported by:Vincent Fortier (Bugzilla Bug 4768) "At boot time the screen appears moved to the mid right portion of the actual video pannel making the end of the line appears at the left edge... It simply looks like moved half way to the right" His particular hardware has a display with an unusual dimension (1920x1200) but unfortunately has no EDID block. None of the entries in the global mode database is correct for this particular display, and it particularly has difficulty scaling up 640x480 (the default startup mode of nvidiafb) to 1920x1200 which causes the above described problem. 1, Add 1920x1200 to the global mode database. 2. Let nvidiafb base the startup mode from the flatpanel dimensions only if the EDID block is absent, no boot mode parameter is specified by the user, and a flatpanel/LCD display is attached.

* [PATCH] namespace.c: fix bind mount from foreign namespaceMiklos Szeredi2005-08-071-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I'm resending this patch, because I still believe it's the correct fix. Tested before/after applying the patch with a test application available from: http://www.inf.bme.hu/~mszeredi/nstest.c Bind mount from a foreign namespace results in an un-removable mount. The reason is that mnt->mnt_namespace is copied from the old mount in clone_mnt(). Because of this check_mnt() in sys_umount() will fail. The solution is to set mnt->mnt_namespace to current->namespace in clone_mnt(). clone_mnt() is either called from do_loopback() or copy_tree(). copy_tree() is called from do_loopback() or copy_namespace(). When called (directly or indirectly) from do_loopback(), always current->namspace is being modified: check_mnt(nd->mnt). So setting mnt->mnt_namespace to current->namspace is the right thing to do. When called from copy_namespace(), the setting of mnt_namespace is irrelevant, since mnt_namespace is reset later in that function for all copied mounts. Jamie said: This patch is correct. The old code was buggy for more fundamental and serious reason: it broke the invariant that a tree of vfsmnts all have the same value of mnt_namespace (and the same for the mnt_list list).

* [PATCH] Fix restore of 64-bit PCI BAR'sIvan Kokshaysky2005-08-071-1/+6
| | | | | | | | | | | | | | For 64-bit BAR[i] only pci_dev->resource[i] is valid, ->resource[i+1] slot is unused and contains zeroes in all fields. So when we update a PCI BAR, all we need is just to check that we're going to update a _valid_ resource. Also make sure to write high bits - use "x >> 16 >> 16" (rather than the simpler ">> 32") to avoid warnings on 32-bit architectures where we're not going to have any high bits.

* [PATCH] blk: fix tag shrinking (revive real_max_size)Tejun Heo2005-08-052-3/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | My patch in commit fa72b903f75e4f0f0b2c2feed093005167da4023 incorrectly removed blk_queue_tag->real_max_depth. The original resize implementation was incorrect in the following points. * actual allocation size of tag_index was shorter than real_max_size, but assumed to be of the same size, possibly causing memory access beyond the allocated area. * bits in tag_map between max_deptn and real_max_depth were initialized to 1's, making the tags permanently reserved. In an attempt to fix above two bugs, I had removed allocation optimization in init_tag_map and real_max_size. Tag map/index were allocated and freed immediately during resize. Unfortunately, I wasn't considering that tag map/index can be resized dynamically with tags beyond new_depth active. This led to accessing freed area after shrinking tags and led to the following bug reporting thread on linux-scsi. http://marc.theaimsgroup.com/?l=linux-scsi&m=112319898111885&w=2 To fix the problem, I've revived real_max_depth without allocation optimization in init_tag_map, and Andrew Vasquez confirmed that the problem was fixed. As Jens is not going to be available for a week, he asked me to make sure that this patch reaches you. http://marc.theaimsgroup.com/?l=linux-scsi&m=112325778530886&w=2 Also, a comment was added to make sure that real_max_size is needed for dynamic shrinking.

| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since the beginning of July my Opteron box was randomly crashing and being rebooted by hardware watchdog. Today it finally did it in front of me, and this patch will hopefully fix it. The problem is that at the end of June (the 28th, to be exact: commit 47f176fdaf8924bc83fddcf9658f2fd3ef60d573, "[PATCH] Using msleep() instead of HZ") rtc_get_rtc_time was converted to use msleep() instead of busy waiting. But rtc_get_rtc_time is used by hpet_rtc_interrupt, and scheduling is not allowed during interrupt. So I'm reverting this part of original change, replacing msleep() back with busy loop. The original code was busy waiting for up to 20ms, but on my hardware in the worst case update-in-progress bit was asserted for at most 363 passes through loop (on 2GHz dual Opteron), much less than even one jiffie, not even talking about 20ms. So I changed code to just wait only as long as necessary. Otherwise when RTC was set to generate 8192Hz timer, it stopped doing anything for 20ms (160 pulses were skipped!) from time to time, and this is rather suboptimal as far as I can tell.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We have found what seems to be a small bug in __vm_enough_memory() when sysctl_overcommit_memory is set to OVERCOMMIT_NEVER. When this bug occurs the systems fails to boot, with /sbin/init whining about fork() returning ENOMEM. We hunted down the problem to this: The deferred update mecanism used in vm_acct_memory(), on a SMP system, allows the vm_committed_space counter to have a negative value. This should not be a problem since this counter is known to be inaccurate. But in __vm_enough_memory() this counter is compared to the `allowed' variable, which is an unsigned long. This comparison is broken since it will consider the negative values of vm_committed_space to be huge positive values, resulting in a memory allocation failure.

* | [PATCH] tcp: fix TSO cwnd caching bugHerbert Xu2005-08-041-25/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | tcp_write_xmit caches the cwnd value indirectly in cwnd_quota. When tcp_transmit_skb reduces the cwnd because of tcp_enter_cwr, the cached value becomes invalid. This patch ensures that the cwnd value is always reread after each tcp_transmit_skb call.
