This patch removes old platform devices. Alsa should now

Add dummy aic23_power_up and aic23_power_down functions for 770

This patch enables writing to McBSP Transmit Configuration Control
Register (XCCR) and Receive Configuration Control Register (RCCR)
for 2430/34xx platforms. It also adds XCCR, RCCR entries in McBSP
register configuration structure and bit definitions for both

If we enable the writing to CCR registers for 2430/34xx and don't
set the default values (setting 0 as a consequence) in ASoC driver,
the Transmit/Receive DMA mode gets disabled and the the
transmission/reception doesn't happen, ending with a
"write error: Input/Output error" when playing with 'aplay'.

Restart the request queue early for REQ_TYPE_PM_RESUME requests

sequence it stays in the queue until is fully completed and now

System calls with an unsigned long long argument can't be converted with

Also semctl can't use the standard wrapper since it has a 'union'

Fix timeouts in sys_pselect7
Since we (Analog Devices) updated our Blackfin kernel to 2.6.28, we've
seen occasional 5-second hangs from telnet. telnetd calls select with a
NULL timeout, but with the new kernel, the system call occasionally
returns 0, which causes telnet to call sleep (5). This did not happen
with earlier kernels.
The code in sys_pselect7 looks a bit strange, in particular the variable
"to" is initialized to NULL, then changed if a non-null timeout was
passed in, but not used further. It needs to be passed to
core_sys_select instead of &end_time.
This bug was introduced by
8ff3e8e85fa6c312051134b3953e397feb639f51

fix early_serial_setup() regression
Commit
b430428a188e8a434325e251d0704af4b88b4711 ("8250: Don't clobber
spinlocks.") introduced a regression on the parisc architecture, which
broke the handover to the serial port at boottime.
early_serial_setup() was changed to only copy a subset of the uart_port
fields, and sadly the "type" and "line" fields were forgotten and thus
the serial port was not initialized and could not be used for a
handover. This patch fixes this by copying the missing fields.
As this change to early_serial_setup() doesn't need an initialized
spinlock in the uart_port struct any longer, we can drop the spinlock
initialization in the superio driver.

this error, with other callers of cpa still getting error here.

x86 PAT: return compatible mapping to remap_pfn_range callers
Impact: avoid warning message, potentially solve 3D performance regression
Change x86 PAT code to return compatible memtype if the exact memtype that
was requested in remap_pfn_rage and friends is not available due to some
conflict.
This is done by returning the compatible type in pgprot parameter of
track_pfn_vma_new(), and the caller uses that memtype for page table.
Note that track_pfn_vma_copy() which is basically called during fork gets the
prot from existing page table and should not have any conflict. Hence we use
strict memtype check there and do not allow compatible memtypes.

x86 PAT: change track_pfn_vma_new to take pgprot_t pointer param
Impact: cleanup
Change the protection parameter for track_pfn_vma_new() into a pgprot_t pointer.
Subsequent patch changes the x86 PAT handling to return a compatible
memtype in pgprot_t, if what was requested cannot be allowed due to conflicts.
No fuctionality change in this patch.

x86 PAT: remove PFNMAP type on track_pfn_vma_new() error
Impact: fix (harmless) double-free of memtype entries and avoid warning
On track_pfn_vma_new() failure, reset the vm_flags so that there will be
no second cleanup happening when upper level routines call unmap_vmas().
This patch fixes part of the bug reported here:
http://marc.info/?l=linux-kernel&m=
123108883716357&w=2
Specifically the error message:
X:5010 freeing invalid memtype
d0000000-
d0101000
Is due to multiple frees on error path, will not happen with the patch below.

powerpc/powermac: Fix occasional SMP boot failure
The PowerMac kernel occasionally fails to bring up the secondary CPUs on
SMP, the trigger factor seem to be fairly random and related to location
of code and data.
This appears to be due to the initial loading of the TOC value by the
secondary processor which now happens before we clear HID4:RM_CI (Real
Mode Cache Invalidate). This bit should really be cleared before we do
any load or store other than fetching code.
This fix works based on the assumption that all SMP 64-bit PowerMacs use
variants of the 970, which fortunately is true, by explicitely clearing
that bit, adding an slbia for good measure as RM_CI mode is known to
create bogus ERAT entries.
I also removed some spurrious debug output that was left enabled by
mistake while at it.
