machine_is() was always returning 0 when used in a module, because we weren't exporting the machine definitions. This was why sound wasn't working on powermacs when CONFIG_SND_POWERMAC=m. Original fix from Ben Herrenschmidt, further fixed by me. Signed-off-by:Paul Mackerras <paulus@samba.org>

I recently found that not all BIOS manufacturers are using the specified generic PNP id in their TPM ACPI table entry. I have added the vendor specific IDs that I know about and added a module parameter that a user can specify another HID to the probe list if their device isn't being found by the default list.

The acpi table which contains the BIOS log events was updated for 1.2. There are now client and server modes as defined in the specifications with slightly different formats. Additionally, the start field was even too small for the 1.1 version but had been working anyway. This patch updates the code to deal with any of the three types of headers probperly (1.1, 1.2 client and 1.2 server). Signed-off-by:

The timeout and duration values used in the tpm driver are not exposed to userspace. This patch converts the storage units to jiffies with msecs_to_jiffies. They were always being used in jiffies so this simplifies things removing the need for calculation all over the place. The change necessitated a type change in the tpm_chip struct to hold jiffies.

Many of the sysfs files were calling the TPM_GetCapability command with array. Since for 1.2 more sysfs files of this type are coming I am generalizing the array so there can be one array and the unique parts can be filled in just before the command is called. This updated version of the patch breaks the multi-value sysfs file into separate files pointed out by Greg. It also addresses the code redundancy and ugliness in the tpm_show_* functions pointed out on another patch by Dave Hansen. Signed-off-by:

With the TPM 1.2 Specification, each command is classified as short, medium or long and the chip tells you the maximum amount of time for a response to each class of command. This patch provides and array of the classifications and a function to determine how long the response should be waited for. Also, it uses that information in the command processing to determine how long to poll for. The function is exported so the 1.2 driver can use the functionality to determine how long to wait for a DataAvailable interrupt if interrupts are being used. Signed-off-by:

Changes in the 1.2 TPM Specification make it necessary to update some fields of the chip structure in the initialization function after it is registered with tpm.c thus tpm_register_hardware was modified to return a pointer to the structure. This patch makes that change and the associated changes in tpm_atmel and tpm_nsc. The changes to tpm_infineon will be coming in a patch from Marcel Selhorst. Signed-off-by:

To assist with chip management and better support the possibility of having multiple TPMs in the system of the same kind, the struct tpm_vendor_specific member of the tpm_chip was changed from a pointer to an instance. This patch changes that declaration and fixes up all accesses to the structure member except in tpm_infineon which is coming in a patch from Marcel Selhorst. Signed-off-by:

The following patch set contains numerous changes to the base tpm driver (tpm.c) to support the next generation of TPM chips. The changes include new sysfs files because of more relevant data being available, a function to access the timeout and duration values for the chip, and changes to make use of those duration values. Duration in the TPM specification is defined as the maximum amount of time the chip could take to return the results. Commands are in one of three categories short, medium and long. Also included are cleanups of how the commands for the sysfs files are composed to reduce a bunch of redundant arrays. This patch: Fix minor spacing issues. Signed-off-by:

reiserfs_cache_default_acl() should return whether we successfully found the acl or not. We have to return correct value even if reiserfs_get_acl() returns error code and not just 0. Otherwise callers such as reiserfs_mkdir() can unnecessarily lock the xattrs and later functions such as reiserfs_new_inode() fail to notice that we have already taken the lock and try to take it again with obvious consequences.

We do this by removing a micro-optimization that tries to avoid grabbing the iommu_bitmap_lock spinlock and using a bus-locked operation. This still races with other simultaneous alloc_iommu or free_iommu(size > 1) which both use bus-unlocked operations. The end result of this race is eventually ending up with an iommu_gart_bitmap that has bits errornously set all over, making large contiguous iommu space allocations fail with 'PCI-DMA: Out of IOMMU space'.

This quietens warnings and actually fixes a bug. The unwind tables would come out wrong without -32, causing pthread cancellation during them to crash in the gcc runtime. The problem seems to only happen with newer binutils (it doesn't happen with 2.16.91.0.2 but happens wit 2.16.91.0.5) Thanks to David Altobelli <david.altobelli@hp.com> and Brian Baker <Brian.B@hp.com> for test case and initial analysis.

Basic problem: pages of a shared memory segment can only be migrated once. In 2.6.16 through 2.6.17-rc1, shared memory mappings do not have a migratepage address space op. Therefore, migrate_pages() falls back to default processing. In this path, it will try to pageout() dirty pages. Once a shared memory page has been migrated it becomes dirty, so migrate_pages() will try to page it out. However, because the page count is 3 [cache + current + pte], pageout() will return PAGE_KEEP because is_page_cache_freeable() returns false. This will abort all subsequent migrations. This patch adds a migratepage address space op to shared memory segments to avoid taking the default path. We use the "migrate_page()" function because it knows how to migrate dirty pages. This allows shared memory segment pages to migrate, subject to other conditions such as # pte's referencing the page [page_mapcount(page)], when requested. I think this is safe. If we're migrating a shared memory page, then we found the page via a page table, so it must be in memory. Can be verified with memtoy and the shmem-mbind-test script, both available at: http://free.linux.hp.com/~lts/Tools/Signed-off-by:

Fix a possible Oops in the Siemens Gigaset base driver when the device is unplugged while an ISDN connection is still active, and makes sure that the isdn4linux link level (LL) is properly informed if a connection is broken by the USB cable being unplugged. - Avoid unsafe checks of URB status fields outside the URB completion handlers, keep track of in-use URBs myself instead. - If an isochronous transfer URB completes with status==0, also check the status of the frame descriptors. - Verify length of interrupt messages received from the device. - Align the length limit on transmitted AT commands with the device documentation. - In case of AT response receive overrun, keep newly arrived instead of old unread data. - Remove redundant check of device ID in the USB probe function. - Correct and improve some comments and formatting.

The new i2c implementation for PowerMac has a regression that causes the hardware to go out of state when probing non-existent devices. While fixing that, I also found & fixed a couple of other corner cases. This fixes booting with a pbbuttons version that scans the i2c bus for an LMU controller among others. Tested on a dual G5 with thermal control (which has heavy i2c activity) with no problem so far. Signed-off-by:

Turn on the DART already at 1GB. This is needed because of crippled devices in some systems, i.e. Airport Extreme cards, only supporting 30-bit DMA addresses. Otherwise, users with between 1 and 2GB of memory will need to manually enable it with iommu=force, and that's no good. Some simple performance tests show that there's a slight impact of enabling DART, but it's in the 1-3% range (kernel build with disk I/O as well as over NFS). iommu=off can still be used for those who don't want to deal with the overhead (and don't need it for any devices).
