* USB: serial: add support for second revision of Ericsson F3507G WWAN cardPatrik Kullman2009-02-271-2/+4

* USB: cdc-acm: add usb id for motomagx phonesDmitriy Taychenachev2009-02-271-0/+2
| | | | | | | | | | | | | The Motorola MOTOMAGX phones (Z6, E8, Zn5 so far) are providing combined ACM/BLAN USB configuration. Since it has Vendor Specific class, the corresponding drivers (cdc-acm, zaurus) can't find it just by interface info. This patch adds usb id so the cdc-acm driver can properly handle this combined device.

* USB: EHCI: slow down ITD reuseKarsten Wiese2009-02-274-8/+57
| | | | | | | | | | | | | | | | | | | | | | | | | Currently ITDs are immediately recycled whenever their URB completes. However, EHCI hardware can sometimes remember some ITD state. This means that when the ITD is reused before end-of-frame it may sometimes cause the hardware to reference bogus state. This patch defers reusing such ITDs by moving them into a new ehci member cached_itd_list. ITDs resting in cached_itd_list are moved back into their stream's free_list once scan_periodic() detects that the active frame has elapsed. This makes the snd_usb_us122l driver (in kernel since .28) work right when it's hooked up through EHCI.

| * Btrfs: try committing transaction before returning ENOSPCJosef Bacik2009-02-201-10/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes a problem where we could return -ENOSPC when we may actually have plenty of space, the space is just pinned. Instead of returning -ENOSPC immediately, commit the transaction first and then try and do the allocation again. This patch also does chunk allocation for metadata if we pass the 80% threshold for metadata space. This will help with stack usage since the chunk allocation will happen early on, instead of when the allocation is happening. Signed-off-by: Josef Bacik <jbacik@redhat.com>
| * Btrfs: add better -ENOSPC handlingJosef Bacik2009-02-206-76/+271
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a step in the direction of better -ENOSPC handling. Instead of checking the global bytes counter we check the space_info bytes counters to make sure we have enough space. If we don't we go ahead and try to allocate a new chunk, and then if that fails we return -ENOSPC. This patch adds two counters to btrfs_space_info, bytes_delalloc and bytes_may_use. bytes_delalloc account for extents we've actually setup for delalloc and will be allocated at some point down the line. bytes_may_use is to keep track of how many bytes we may use for delalloc at some point. When we actually set the extent_bit for the delalloc bytes we subtract the reserved bytes from the bytes_may_use counter. This keeps us from not actually being able to allocate space for any delalloc bytes. Signed-off-by: Josef Bacik <jbacik@redhat.com>

This commit allowed CPUs that have the CPU_FTR_UNALIGNED_LD_STD CPU feature bit present to do the memcpy() with unaligned load doubles. But, along with this came a bug where our final load double would read bytes beyond a page boundary and into the next (unmapped) page. This was caught by enabling CONFIG_DEBUG_PAGEALLOC, The fix was to read only the number of bytes that we need to store rather than reading a full 8-byte doubleword and storing only a portion of that. In order to minimise the amount of existing code touched we use the original do_tail for the src_unaligned case.

This means we must disable the FIFO for ATAPI where a final 16bit cycle may occur. Rework the FIFO logic so that we disable the FIFO then selectively re-enable it when we set the timings on AMD devices. Also fix a case where we scribbled on PCI config 0x41 of Nvidia chips when we shouldn't.

If the bootloader has touched the SATA controller before starting Linux, Linux can end up enabling the SATA interrupt with events pending, which will cause the interrupt to be marked as spurious and then be disabled, which then breaks all further accesses to the controller. This patch makes the SoC path clear interrupt status on init like in the non-SoC case.

I did some debugging (booting with no_console_suspend init=/bin/sh). Found that resume fails (2.6.28) with "serial number mismatch 'some garbage' != 'some other garbage'" and "revalidation failed" messages. That's because the controller firmware fills different serial number in the IDENTIFY every boot. The patch below fixes the resume simply clearing the serial number. The proper fix would be probably to fill in the serial number of the RAID volume instead. I assume that there must be something like that stored on the drives but I don't know where. Fix resume on pata_it821x RAID volume by clearing the serial number in IDENTIFY data, which is otherwise different on each boot.

Commit fc8744adc870a8d4366908221508bb113d8b72ee "Stop playing silly games with the VM_ACCOUNT flag" changed shmem_file_setup() to set the shmem file's VM_ACCOUNT flag according to VM_NORESERVE not being set in the vma flags; but did so only _after_ the shmem_acct_size(flags, size) call which is expected to pre-account a shared anonymous object. It's all clearer if we switch shmem.c over to use VM_NORESERVE throughout in place of !VM_ACCOUNT. But I very nearly sent in a patch which mistakenly removed the accounting from tmpfs files: shmem_get_inode()'s memset was good for not setting VM_ACCOUNT, but now it needs to set VM_NORESERVE. Rather than setting that by default, then perhaps clearing it again in shmem_file_setup(), let's pass it as a flag to shmem_get_inode(): that allows us to remove the #ifdef CONFIG_SHMEM from shmem_file_setup().
