Do not change apic_base directly. Use kvm_lapic_set_base() instead. Signed-off-by:
-
Gleb Natapov authored
kvm_get_apic_base() needlessly checks irqchip_in_kernel although it does the same no matter what result of the check is. kvm_set_apic_base() also checks for irqchip_in_kernel, but kvm_lapic_set_base() can handle this case. Signed-off-by:

Currently, we use the error code as error pfn to indicat the error condition, it is not straightforward and it will not work on PAE 32-bit cpu with huge memory, since the valid physical address can be at most 52 bits For the normal pfn, the highest 12 bits should be zero, so we can mask these bits to indicate the error.

There are two bugs: - the 'error page' is forgot to be released [ it is unneeded after commit a2766325, for backport, we still do kvm_release_pfn_clean for the error pfn ] - guest pages are always released regardless of the unmapped page (e,g, caused by hwpoison) Signed-off-by:

Two reasons: - x86 can integrate rmap and rmap_pde and remove heuristics in __gfn_to_rmap(). - Some architectures do not need rmap. Since rmap is one of the most memory consuming stuff in KVM, ppc'd better restrict the allocation to Book3S HV. Signed-off-by:

Pull VFS fixes and cleanups from Al Viro. Most of this is the series to remove sync_supers() and the ->write_supers VFS callback from Artem Bityutskiy. One commit to do the actual removal work, a whole series of commits to fix up stale comments etc all over the tree. There's also a regression fix for an incorrect use of mnt_drop_write() in do_dentry_open(). * 'for-linus-2' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: missed mnt_drop_write() in do_dentry_open() UBIFS: nuke pdflush from comments gfs2: nuke pdflush from comments drbd: nuke pdflush from comments nilfs2: nuke write_super from comments hfs: nuke write_super from comments vfs: nuke pdflush from comments jbd/jbd2: nuke write_super from comments btrfs: nuke pdflush from comments btrfs: nuke write_super from comments ext4: nuke pdflush from comments ext4: nuke write_super from comments ext3: nuke write_super from comments Documentation: fix the VM knobs descritpion WRT pdflush Documentation: get rid of write_super vfs: kill write_super and sync_supers

Finally we can kill the 'sync_supers' kernel thread along with the '->write_super()' superblock operation because all the users are gone. Now every file-system is supposed to self-manage own superblock and its dirty state. The nice thing about killing this thread is that it improves power management. Indeed, 'sync_supers' is a source of monotonic system wake-ups - it woke up every 5 seconds no matter what - even if there were no dirty superblocks and even if there were no file-systems using this service (e.g., btrfs and journalled ext4 do not need it). So it was wasting power most of the time. And because the thread was in the core of the kernel, all systems had to have it. So I am quite happy to make it go away. Interestingly, this thread is a left-over from the pdflush kernel thread which was a self-forking kernel thread responsible for all the write-back in old Linux kernels. It was turned into per-block device BDI threads, and 'sync_supers' was a left-over. Thus, R.I.P, pdflush as well. Signed-off-by:
