* export ata_host_intr * fix debugging printk * the write of Device Control register, which occurs between SATA phy reset and the read of device signature, apparently clobbers some of the register values (namely Error register) that are needed to determine whether or not the device passed diagnostics. Make this write follow the device diag checking and classification, instead.

Most ATA host controllers follow a standard layout for the ATA shadow registers, where command/status, error/feature, and devctl/altstatus share a single bus I/O address, because one register of each pair is read-only, and the other is write-only. On the Vitesse/Intel chip, all registers are given distinction bus I/O addresses, which necessitates changing the libata data structures to cope with this. This simply involves storing a few more bus addresses.

This is a cleaner fix for the previous bogon fix.

- Move free_block prototype, and ac_entry and ac_data functions up in file. - Use list_for_each_entry in cpuup_callback. - Remove unneccessary g_cpucache_up in cpuup_callback. - Make reap_timer_func take CPU number as data, and check if that is offline before rescheduing (noop without CONFIG_HOTPLUG_CPU).

Levent Serinol <levent.serinol@mynet.com> found that the hotplug cpu patch broke Sparc64. I introduced a num_possible_cpus(), which Sparc64 already has. Remove the Sparc64 one. I also removed Sparc64's cpu_online() macro: it's in linux/cpumask.h already.

Note that without CONFIG_HOTPLUG_CPU, online cpus == possible cpus, so substitutions are a noop. - Changes show_stat to print out stats for every possible cpu, not just online CPUs. - Allocate mem in stat_open on possible, not online_cpus. - Add conventient macros to cpu.h: especially cpu_is_offline() for testing if a cpu is still online. - Add a num_possible_cpus() similar to num_online_cpus(), and define cpu_possible_mask for UP. - Allow printk on down cpus once system is running. - Mask cpumask with possible, not online cpus, for sys_getaffinity().

Extracts core of drain_pages() for hotcpu use. Trivial. Hotplug CPU needs to drain pages on a downed CPU (usually it's the current cpu). Introduce "__drain_pages", make the CPU an argument, and expose it if CONFIG_HOTPLUG_CPU as well as CONFIG_PM.

Promise driver uses a custom error handling function, so we need the fix that was applied to the libata core: the SCSI error handling thread requires that we complete commands using a special completion function, since the normal one doesn't work inside the error handling thread.

The following patch is a very crude one to at least not make sata block suspend-to-ram entirely. Probably you want more powermanagement handling as well... but it's a start

The pcnet32 driver will hang after a few frames (<30) with the 79C971 (and probably the 79C972 though I don't have the hardware to prove it). By interrupting slightly more frequently the hang will not occur.

It really looks like the new EISA probing code in hp100 never got tested, since a precious offset has disappeared during the rewriting process. Please note that you still need to enable the device by hand, since your BIOS (or maybe the EISA CFG file, since I'm seeing the exact same problem on a Compaq machine here) doesn't properly enable the card. Here is what I'm getting on my test system : EISA: Probing bus 0 at 0000:00:0f.0 EISA: Mainboard CPQ0541 detected. EISA: slot 1 : DEC4250 detected. EISA: slot 2 : UNB0048 detected.

EISA: slot 4 : NVL0701 detected.

Now we've moved the bogolock code out to stop_machine.c and generalized it a little, use it in module.c and delete the duplicate code there.
-
Rusty Russell authored
The "bogolock" code was introduced in module.c, as a way of freezing the machine when we wanted to remove a module. This patch moves it out to stop_machine.c and stop_machine.h. Since the code changes affinity and proirity, it's impolite to hijack the current context, so we use a kthread. This means we have to pass the function rather than implement "stop_machine()" and "restart_machine()".

Committing a transaction creating a file required insuring that the inode stayed in cache until the journal was written to. i_count was being incremented until the transaction was complete. However, incrementing i_count caused fcntl(S_SETLEASE) to fail. I reworked the transaction code so that the inode does not have to stay in-memory while the transaction is being committed. Thanks to Steve French for figuring out why setlease was failing.

When no iocharset is specified, the default action is to trivially map each byte into the low order of the 16-bit unicode character. If an existing name exists that has a non-zero high order byte, the file will be inaccessible without remounting with iocharset set to a charset that supports the character. This patch will cause a warning to be issued to the syslog (no more than five times) suggesting that the volume be mounted with iocharset=utf8 in order to access the file.

From: Hugh Dickins <hugh@veritas.com> Fixes bugzilla #2219 fork's dup_mmap leaves child mm_rb as copied from parent mm while doing all the copy_page_ranges, and then calls build_mmap_rb without holding page_table_lock. try_to_unmap_one's find_vma (holding page_table_lock not mmap_sem) coming on another cpu may cause mm mayhem. It may leave the child's mmap_cache pointing to a vma of the parent mm. When the parent exits and the child faults, quite what happens rather depends on what junk then inhabits vm_page_prot, which gets set in the page table, with page_add_rmap adding the ptep, but junk pte likely to fail the tests for page_remove_rmap. Eventually the child exits, the page table is freed and try_to_unmap_one oopses on null ptep_to_mm (but in a kernel with rss limiting, usually page_referenced hits the null ptep_to_mm first). This took me days and days to unravel! Big thanks to Matthieu for reporting it with a good test case.

Noted by Stephen Smalley: sys_acct does not properly clean up the open file when the security_acct hook returns an error. Fixed thus.

Here's the second attempt at fixing blk_start_queue(). The only change since last version is using proper atomic bitops. If we moved the read/write full to a different variable, we could rely on the queue lock for plugging and stop/start of queue (by far the most used bit operations there) and skip the atomic bitops.
