A proper fix would involve introducing the notion of shared caches but
at this stage of 2.6.17 that's going to be too intrusive and not needed
for current hardware; aside I think some discussion will be needed.
So for now on the affected SMP configurations which happen to suffer from
cache aliases we make use of the fact that a single cache will be shared
by all processors. This solves the deadlock issue and will improve
performance by getting rid of the smp_call_function overhead.

In case of CONFIG_64BIT_PHYS_ADDR, set_pte() and pte_clear() functions
only set _PAGE_GLOBAL bit in the pte_low field of the buddy PTEs,
forgetting to propagate ito to pte_high. Thus, the both pages might not
really be made global for the CPU (since it AND's the G-bit of the
odd / even PTEs together to decide whether they're global or not). Thus,
if only a single page is allocated via vmalloc() or ioremap(), it's not
really global for CPU (and it must be, since this is kernel mapping),
and thus its ASID is compared against the current process' one -- so,
we'll get into trouble sooner or later... Also, pte_none() will fail
on global pages because _PAGE_GLOBAL bit is set in both pte_low and
pte_high, and pte_val() will return u64 value consisting of those fields
concateneted.

If an error is reported by a drive in a RAID array (which is done via
bi_end_io - in interrupt context), we call md_error and md_new_event which
calls sysfs_notify. However sysfs_notify grabs a mutex and so cannot be
called in interrupt context.
This patch just creates a variant of md_new_event which avoids the sysfs
call, and uses that. A better fix for later is to arrange for the event to
be called from user-context.
Note: avoiding the sysfs call isn't a problem as an error will not, by
itself, modify the sync_action attribute. (We do still need to
wake_up(&md_event_waiters) as an error by itself will modify /proc/mdstat).

This patch is pretty important to get in for IPMI, new systems have been

IPMI.
Fixed releasing already-allocated regions when a later request fails, and
forward-ported it to HEAD.
Some BIOSes reserve disjoint I/O regions in their ACPI tables for the IPMI
controller. This causes problems when trying to register the entire I/O

Change the binary output format to actual ACPI TCPA log structure since the
current format does not contain all event-data information that need to
verify the PCRs in TPM. tpm_binary_bios_measurements_show() uses
get_event_name() to convert the binary event-data to ascii format, and puts
them as binary. However, to verify the PCRs, the event-data must be a
actual binary event-data used by SHA1 calc. in BIOS.
So, I think actual ACPI TCPA log is good for this binary output format.
That way, any userland tools easily parse this data with reference to TCG

o Kdump capture kernel boot fails during initialization of MPT fusion driver.
(LSI Logic / Symbios Logic SAS1064E PCI-Express Fusion-MPT SAS (rev 01))
o Problem is easily reproducible, if system crashed while some disk activity
like cp operation was going on.
o After a system crash, devices are not shutdown and capture kernel starts
booting while skipping BIOS. Hence underlying device is left in operational
state. In this case scsi contoller was left with interrupt line asserted
reply FIFO was not empty. When driver starts initializing in the second
kernel, it receives the interrupt the moment request_irq() is called.
Interrupt handler, reads the message from reply FIFO and tries to access
the associated message frame and panics, as in the new kernel's context
that message frame is not valid at all.
o In this scenario, probably we should delay the request_irq() call. First
bring up the IOC, reset it if needed and then should register for irq.
o I have tested the patch with SAS1064E and 53c1030 controllers.

while (bad_addr(&addr, size) && addr+size < ei->addr + ei->size)
;
last = addr + size;
if ( last > ei->addr + ei->size )
continue;
The second statement in the while loop needs to be a <= b so that it is the
logical negavite of the if (a > b) outside it. It needs to read:
while (bad_addr(&addr, size) && addr+size <= ei->addr + ei->size)
;
In the case that failed bad_addr was returning an address that is exactly size
bellow the end of the e820 range.

- the multiplication of offset_delay and cpu_khz (both being 32-bit
