2010-04-20KVM: fix the handling of dirty bitmaps to avoid overflowsTakuya Yoshikawa
Int is not long enough to store the size of a dirty bitmap. This patch fixes this problem with the introduction of a wrapper function to calculate the sizes of dirty bitmaps. Note: in mark_page_dirty(), we have to consider the fact that __set_bit() takes the offset as int, not long.

2010-04-20KVM: VMX: Save/restore rflags.vm correctly in real modeAvi Kivity
Currently we set eflags.vm unconditionally when entering real mode emulation through virtual-8086 mode, and clear it unconditionally when we enter protected mode. The means that the following sequence KVM_SET_REGS (rflags.vm=1) KVM_SET_SREGS (cr0.pe=1) Ends up with rflags.vm clear due to KVM_SET_SREGS triggering enter_pmode(). Fix by shadowing rflags.vm (and rflags.iopl) correctly while in real mode: reads and writes to those bits access a shadow register instead of the actual register.

2010-04-20KVM: allow bit 10 to be cleared in MSR_IA32_MC4_CTLAndre Przywara
There is a quirk for AMD K8 CPUs in many Linux kernels (see arch/x86/kernel/cpu/mcheck/mce.c:__mcheck_cpu_apply_quirks()) that clears bit 10 in that MCE related MSR. KVM can only cope with all zeros or all ones, so it will inject a #GP into the guest, which will let it panic. So lets add a quirk to the quirk and ignore this single cleared bit. This fixes -cpu kvm64 on all machines and -cpu host on K8 machines with some guest Linux kernels. Signed-off-by: Andre Przywara <andre.przywara@amd.com> Signed-off-by: Avi Kivity <avi@redhat.com>

2010-04-20Input: Add support of Synaptics Clickpad deviceTakashi Iwai
The new type of touchpads can be detected via a new query command 0x0c. The clickpad flags are in cap[0]:4 and cap[1]:0 bits. When the device is detected, the driver now reports only the left button as the supported buttons so that X11 driver can detect that the device is Clickpad. A Clickpad device gives the button events only as the middle button. The kernel driver morphs to the left button. The real handling of Clickpad is done rather in X driver side.

2010-04-19rmap: add exclusively owned pages to the newest anon_vmaRik van Riel
The recent anon_vma fixes cause many anonymous pages to end up in the parent process anon_vma, even when the page is exclusively owned by the current process. Adding exclusively owned anonymous pages to the top anon_vma reduces rmap scanning overhead, especially in workloads with forking servers. This patch adds a parameter to __page_set_anon_rmap that can be used to indicate whether or not the added page is exclusively owned by the current process. Pages added through page_add_new_anon_rmap are exclusively owned by the current process, and can be added to the top anon_vma. Pages added through page_add_anon_rmap can be either shared or exclusively owned, so we do the conservative thing and add it to the oldest anon_vma. A next step would be to add the exclusive parameter to page_add_anon_rmap, to be used from functions where we do know for sure whether a page is exclusively owned.

2010-04-19mac80211: pass HT changes to driver when off channelReinette Chatre
Since "mac80211: make off-channel work generic" drivers have not been notified of configuration changes after association or authentication. This caused more dependence on current state to ensure driver will be notified when configuration changes occur. One such problem arises if off-channel is in progress when HT information changes. Since HT is only enabled on the "oper_channel" the driver will never be notified of this change. Usually the driver is notified soon after of a BSS information change (BSS_CHANGED_HT) ... but since the driver did not get a notification that this is a HT channel the new BSS information does not make sense. Fix this by also changing the off-channel information when HT is enabled and thus cause driver to be notified correctly. This fixes a problem in 4965 when associated with 5GHz 40MHz channel. Without this patch the system can associate but is unable to transfer any data, not even ping.

2010-04-19ecryptfs: fix use with tmpfs by removing d_drop from ecryptfs_destroy_inodeJeff Mahoney
Since tmpfs has no persistent storage, it pins all its dentries in memory so they have d_count=1 when other file systems would have d_count=0. ->lookup is only used to create new dentries. If the caller doesn't instantiate it, it's freed immediately at dput(). ->readdir reads directly from the dcache and depends on the dentries being hashed. When an ecryptfs mount is mounted, it associates the lower file and dentry with the ecryptfs files as they're accessed. When it's umounted and destroys all the in-memory ecryptfs inodes, it fput's the lower_files and d_drop's the lower_dentries. Commit 4981e081 added this and a d_delete in 2008 and several months later commit caeeeecf removed the d_delete. I believe the d_drop() needs to be removed as well. The d_drop effectively hides any file that has been accessed via ecryptfs from the underlying tmpfs since it depends on it being hashed for it to be accessible. I've removed the d_drop on my development node and see no ill effects with basic testing on both tmpfs and persistent storage. As a side effect, after ecryptfs d_drops the dentries on tmpfs, tmpfs BUGs on umount. This is due to the dentries being unhashed. tmpfs->kill_sb is kill_litter_super which calls d_genocide to drop the reference pinning the dentry. It skips unhashed and negative dentries, but shrink_dcache_for_umount_subtree doesn't. Since those dentries still have an elevated d_count, we get a BUG(). This patch removes the d_drop call and fixes both issues.

2010-04-19firewire: core: fix retries calculation in iso manage_channel()Clemens Ladisch
If there is a permanent error condition when communicating with the IRM, after the sixth error, the retry variable will be decremented to -1. If, in this case, the bits in channels_mask are not yet exhausted, the next channel is retried 2^32 times. To fix this, check that retry is never decremented beyond zero.

2010-04-19ALSA: hda - Fix resume from StR of HP 2510p with docking-stationTakashi Iwai
When HP laptop with AD1981 codec is suspended and the docking-station is connected before the resume, the outputs get confused, and wrongly routed still to the speaker. This is because of a change in 2.6.34-rc1 ea52bf260ecbb175339af3178c15788df21b7516 ALSA: hda: Add powerdown for Analog Devices HDA codecs The problem was the added resume callback that doesn't consider the modified init hook. The fix is simply remove the resume callback here and make the resume normally. This doesn't change any behavior intended in the commit above (for shutting down the sound at suspend) but only fixes the resume.
