* SLUB: Do our own flags based on PG_active and PG_errorChristoph Lameter2007-05-171-14/+14
| | | | | | | | | | | The atomicity when handling flags in SLUB is not necessary since both flags used by SLUB are not updated in a racy way. Flag updates are either done during slab creation or destruction or under slab_lock. Some of these flags do not have the non atomic variants that we need. So define our own.

| | | | | | | | | | | | | Align the output of % with K/M/G of sizes.

* slub: fix handling of oversized slabsAndrew Morton2007-05-171-1/+6
| | | | | | | | | | | | | | | I'm getting zillions of undefined references to __kmalloc_size_too_large on alpha. For some reason alpha is building out-of-line copies of kmalloc_slab() into lots of compilation units. It turns out that gcc just isn't smart enough to work out that __builtin_contant_p(size)==true implies that __builtin_contant_p(index)==true. So let's give it a bit of help.

* slab: warn on zero-length allocationsChristoph Lameter2007-05-171-0/+1

* Slab allocators: Drop support for destructorsChristoph Lameter2007-05-174-62/+16
| | | | | | | | | | | | | | | | | | | | | There is no user of destructors left. There is no reason why we should keep checking for destructors calls in the slab allocators. The RFC for this patch was discussed at http://marc.info/?l=linux-kernel&m=117882364330705&w=2 Destructors were mainly used for list management which required them to take a spinlock. Taking a spinlock in a destructor is a bit risky since the slab allocators may run the destructors anytime they decide a slab is no longer needed. Patch drops destructor support. Any attempt to use a destructor will BUG().

| | | | | | | | | | | | | | | | | | | | | | Our assumption that most distros issue STANDBYNOW seems wrong. The upstream sysvinit and thus many distros including gentoo and opensuse don't take any action for libata disks on spindown.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Unlocking ap->lock and ssleeping don't work because SCSI commands can be issued from completion path without context. Reimplement delayed completion by allowing translation functions to override qc->scsidone(), storing the original completion function to scmd->scsi_done() and overriding qc->scsidone() with a function which schedules delayed invocation of scmd->scsi_done(). This isn't pretty at all but all the ugly parts are thankfully contained in the stop translation path where the compat feature is implemented.

| | | | | | | | | | | | | | | | | | | | | | | | Whether a controller needs IDE or SATA ACPI hierarchy is determined by the programming interface of the controller not by whether the controller is SATA or PATA, or it supports slave device or not.

| * libata: during revalidation, check n_sectors after device is configuredTejun Heo2007-05-162-19/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Device might be resized during ata_dev_configure() due to HPA or (later) ACPI _GTF. Currently it's worked around by caching n_sectors before turning off HPA. The cached original size is overwritten if the device is reconfigured without being hardreset - which always happens after configuring trasnfer mode. If the device gets hardreset for some reason after that, revalidation fails with -ENODEV. This patch makes size checking more robust by moving n_sectors check from ata_dev_reread_id() to ata_dev_revalidate() after the device is fully configured. No matter what happens during configuration, a device must have the same n_sectors after fully configured to be treated as the same device.

So add a small set of interfaces to request API versions and query current settings. This allows us to fix some bugs in the hypervisor console: 1) If we can negotiate API group CORE of at least major 1 minor 1 we can use con_read and con_write which can improve console performance quite a bit. 2) When we do a console write request, we should hold the spinlock around the whole request, not a byte at a time. What would happen is that it's easy for output from different cpus to get mixed with each other. 3) Use consistent udelay() based polling, udelay(1) each loop with a limit of 1000 polls to handle stuck hypervisor console.

This patch moves kdump entry points to DIE_INIT_MONARCH_LEAVE and DIE_INIT_SLAVE_LEAVE. It also sets kdump_in_progress variable in the DIE_INIT_MONARCH_PROCESS event to not dump all active stack traces to the console in the case of kdump. I have tested this patch on an SN machine and a HP RX2600. Signed-off-by: Jay Lan <jlan@sgi.com> Acked-by: Zou Nan hai <nanhai.zou@intel.com> Signed-off-by: Tony Luck <tony.luck@intel.com>

However, that broke the nesting logic of suspend and resume, and we continued to suspend the devices _after_ we the ACPI device suspend code was called. That resulted in us saving PCI state for devices that had already been changed by ACPI, and in some cases disabled entirely (causing the PCI save_state to be all-ones). Which in turn caused the wrong state to be written back on resume. This moves the ACPI device suspend to after the device model per-device suspend() calls. This fixes the bogus state save.
