dcdbas: force SMI to happen when expected

2011-03-28T14:31:23+00:00

commit dd65c736d1b5312c80c88a64bf521db4959eded5 upstream.

The dcdbas driver can do an I/O write to cause a SMI to occur.  The SMI handler
looks at certain registers and memory locations, so the SMI needs to happen
immediately.  On some systems I/O writes are posted, though, causing the SMI to
happen well after the "outb" occurred, which causes random failures.  Following
the "outb" with an "inb" forces the write to go through even if it is posted.

firmware: only allow EDD on x86

2009-12-15T16:53:34+00:00

Rather than have the EDD depend on !ia64 (and assuming that only ia64,
x86, x86_64 will be including this Kconfig), have EDD depend on the only
arches which can support this code.  This should allow all other arches to
cleanly include the firmware Kconfig.

Also simplify the x86 string used by FIRMWARE_MEMMAP to match EDD.

firmware_class: make request_firmware_nowait more useful

2009-12-11T19:24:52+00:00

Unfortunately, one cannot hold on to the struct firmware
that request_firmware_nowait() hands off, which is needed
in some cases. Allow this by requiring the callback to
free it (via release_firmware).

Additionally, give it a gfp_t parameter -- all the current
users call it from a GFP_KERNEL context so the GFP_ATOMIC
isn't necessary. This also marks an API break which is
useful in a sense, although that is obviously not the
primary purpose of this change.

DMI: allow omitting ident strings in DMI tables

2009-12-05T06:10:59+00:00

The purpose of dmi->ident is twofold - it may be used by DMI callback
functions when composing log messages; it is also used to determine
end of DMI table in dmi_check_system() and dmi_first_match(). However,
in case when callbacks are not interested in using ident at all it just
wastes memory. Let's make entries with empty first match slot serve as
end-of-table markers instead.

iSCSI/iBFT: use proper address translation

2009-10-05T19:05:40+00:00

In virtual environments (namely, Xen Dom0) virt <-> phys and
virt <-> isa-bus translations cannot be freely interchanged (and
even outside such environments it is not really correct to do so).
When looking at memory below 1M, the latter translations should
always be used.

mm: don't use alloc_bootmem_low() where not strictly needed

2009-09-22T14:17:38+00:00

Since alloc_bootmem() will never return inaccessible (via virtual
addressing) memory anyway, using the ..._low() variant only makes sense
when the physical address range of the allocated memory must fulfill
further constraints, espacially since on 64-bits (or more generally in all
cases where the pools the two variants allocate from are than the full
available range.

Probably the use in alloc_tce_table() could also be eliminated (based on
code inspection of pci-calgary_64.c), but that seems too risky given I
know nothing about that hardware and have no way to test it.

driver model: constify attribute groups

2009-09-15T16:50:47+00:00

Let attribute group vectors be declared "const".  We'd
like to let most attribute metadata live in read-only
sections... this is a start.

dmi: extend dmi_get_year() to dmi_get_date()

2009-09-09T01:17:48+00:00

There are cases where full date information is required instead of
just the year.  Add month and day parsing to dmi_get_year() and rename
it to dmi_get_date().

As the original function only required '/' followed by any number of
parseable characters at the end of the string, keep that behavior to
avoid upsetting existing users.

The new function takes dates of format [mm[/dd]]/yy[yy].  Year, month
and date are checked to be in the ranges of [1-9999], [1-12] and
[1-31] respectively and any invalid or out-of-range component is
returned as zero.

The dummy implementation is updated accordingly but the return value
is updated to indicate field not found which is consistent with how
other dummy functions behave.

dmi: fix date handling in dmi_get_year()

2009-09-09T01:17:47+00:00

Year parsing in dmi_get_year() had the following two bugs.

* "00" is treated as invalid instead of 2000 because zero return from
  simple_strtoul() is treated as error.

* "0N" where N >= 8 is treated as invalid of 200N because the leading
  0 is considered to specify octal.

Fix the above two bugs by using endptr to detect invalid number and
forcing decimal.
