2008-10-10x86: track memtype for RAM in page structSuresh Siddha2-0/+3
Track the memtype for RAM pages in page struct instead of using the memtype list. This avoids the explosion in the number of entries in memtype list (of the order of 20,000 with AGP) and makes the PAT tracking simpler. We are using PG_arch_1 bit in page->flags. We still use the memtype list for non RAM pages.

2008-10-10x86, cpa: remove USER permission from the very early identity mapping attributeSuresh Siddha1-2/+2
remove USER from the PTE/PDE attributes for the very early identity mapping. We overwrite these mappings with KERNEL attribute later in the boot. Just being paranoid here as there is no need for USER bit to be set. If this breaks something(don't know the history), then we can simply drop this change.

The previous patch db203d53d474aa068984e409d807628f5841da1b ("mm: tiny-shmem fix lock ordering: mmap_sem vs i_mutex") to fix the lock ordering in tiny-shmem breaks shared anonymous and IPC memory on NOMMU architectures because it was using the expanding truncate to signal ramfs to allocate a physically contiguous RAM backing the inode (otherwise it is unusable for "memory mapping" it to userspace). However do_truncate is what caused the lock ordering error, due to it taking i_mutex. In this case, we can actually just call ramfs directly to allocate memory for the mapping, rather than go via truncate.

2008-09-30sctp: Fix kernel panic while process protocol violation parameterWei Yongjun1-0/+3
Since call to function sctp_sf_abort_violation() need paramter 'arg' with 'struct sctp_chunk' type, it will read the chunk type and chunk length from the chunk_hdr member of chunk. But call to sctp_sf_violation_paramlen() always with 'struct sctp_paramhdr' type's parameter, it will be passed to sctp_sf_abort_violation(). This may cause kernel panic. sctp_sf_violation_paramlen() |-- sctp_sf_abort_violation() |-- sctp_make_abort_violation() This patch fixed this problem.

2008-09-29hrtimer: prevent migration of per CPU hrtimersThomas Gleixner1-3/+11
Impact: per CPU hrtimers can be migrated from a dead CPU The hrtimer code has no knowledge about per CPU timers, but we need to prevent the migration of such timers and warn when such a timer is active at migration time. Explicitely mark the timers as per CPU and use a more understandable mode descriptor for the interrupts safe unlocked callback mode, which is used by hrtimer_sleeper and the scheduler code.

2008-09-29hrtimer: mark migration stateThomas Gleixner1-1/+3
Impact: during migration active hrtimers can be seen as inactive The migration code removes the hrtimers from the queues of the dead CPU and sets the state temporary to INACTIVE.

2008-09-29libata: Implement disk shock protection supportElias Oltmanns1-2/+11
On user request (through sysfs), the IDLE IMMEDIATE command with UNLOAD FEATURE as specified in ATA-7 is issued to the device and processing of the request queue is stopped thereafter until the specified timeout expires or user space asks to resume normal operation. This is supposed to prevent the heads of a hard drive from accidentally crashing onto the platter when a heavy shock is anticipated (like a falling laptop expected to hit the floor). In fact, the whole port stops processing commands until the timeout has expired in order to avoid any resets due to failed commands on another device.

2008-09-29libata: implement slave_linkTejun Heo1-3/+5
Explanation taken from the comment of ata_slave_link_init(). In libata, a port contains links and a link contains devices. There is single host link but if a PMP is attached to it, there can be multiple fan-out links. On SATA, there's usually a single device connected to a link but PATA and SATA controllers emulating TF based interface can have two - master and slave. However, there are a few controllers which don't fit into this abstraction too well - SATA controllers which emulate TF interface with both master and slave devices but also have separate SCR register sets for each device. These controllers need separate links for physical link handling (e.g. onlineness, link speed) but should be treated like a traditional M/S controller for everything else (e.g. command issue, softreset). slave_link is libata's way of handling this class of controllers without impacting core layer too much. For anything other than physical link handling, the default host link is used for both master and slave. For physical link handling, separate @ap->slave_link is used. All dirty details are implemented inside libata core layer. From LLD's POV, the only difference is that prereset, hardreset and postreset are called once more for the slave link, so the reset sequence looks like the following. prereset(M) -> prereset(S) -> hardreset(M) -> hardreset(S) -> softreset(M) -> postreset(M) -> postreset(S) Note that softreset is called only for the master. Softreset resets both M/S by definition, so SRST on master should handle both (the standard method will work just fine). As slave_link excludes PMP support and only code paths which deal with the attributes of physical link are affected, all the changes are localized to libata.h, libata-core.c and libata-eh.c. * ata_is_host_link() updated so that slave_link is considered as host link too. * iterator extended to iterate over the slave_link when using the underbarred version. * force param handling updated such that devno 16 is mapped to the slave link/device. * ata_link_on/offline() updated to return the combined result from master and slave link. ata_phys_link_on/offline() are the direct versions. * EH autopsy and report are performed separately for master slave links. Reset is udpated to implement the above described reset sequence. Except for reset update, most changes are minor, many of them just modifying dev->link to ata_dev_phys_link(dev) or using phys online test instead. After this update, LLDs can take full advantage of per-dev SCR registers by simply turning on slave link. Signed-off-by: Tejun Heo <tj@kernel.org> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

2008-09-29libata: make SCR access ops per-linkTejun Heo1-2/+2
Logically, SCR access ops should take @link; however, there was no compelling reason to convert all SCR access ops when adding @link abstraction as there's one-to-one mapping between a port and a non-PMP link. However, that assumption won't hold anymore with the scheduled addition of slave link. Make SCR access ops per-link.

When we use > 4KB's page size the original definition is not consistent with PGDIR_SIZE. For exeample, if we use 16KB page size the PGDIR_SHIFT is (14-2) + 14 = 26, PGDIR_SIZE is 2^26，so the PTRS_PER_PGD should be: 2^32/2^26 = 2^6 but the original definition of PTRS_PER_PGD is 4096 (PGDIR_ORDER = 0).
