Grant Likely aaab5e83c2 powerpc/mpc5200: Disable bestcomm prefetching when ATA DMA enabled
When ATA DMA is enabled, bestcomm prefetching does not work.  This
patch adds a function to disable bestcomm prefetch when the ATA
Bestcomm task is initialized.

Tim Yamin e4efe3c271 powerpc/mpc5200: Bestcomm fixes to ATA support
1) ata.h has dst_pa in the wrong place (needs to match what the BestComm
   task microcode in bcom_ata_task.c expects); fix it.

2) The BestComm ATA task priority was changed to maximum in bestcomm_priv.h;
   this fixes a deadlock issue experienced with heavy DMA occurring on
   both the ATA and Ethernet BestComm tasks, e.g. when downloading a large
   file over a LAN to disk.

Grant Likely 622882455a powerpc/mpc5200: Bugfix on handling variable sized buffer descriptors
The buffer descriptors for the ATA BestComm task are larger than the
current definition for bcom_bd.  This causes problems because the
various bcom_... functions dereference the buffer descriptor pointer
by using the array operator which doesn't work when the buffer
descriptors are a different size.

This patch adds the bcom_get_bd() function which uses the value in
bcom_task.bd_size to calculate the offset into the BD table.  This
patch also changes the definition of bcom_bd to specify a data size
of 0 instead of 1 so that it will never work if anyone attempts to
dereference the bd list as an array (as opposed to something that
might work even though it is wrong).

Finally, this patch moves the definition of bcom_bd up in the file
to eliminate a forward declaration.

Based on patch originally written by Tim Yamin.

The MPC5200 internal interrupt controller setup function needs to set
the default interrupt controller when it is called.  Without this
irq_create_of_mapping() cannot be called without first determining

Grant Likely bcb73f5611 powerpc/mpc5200: Document and tidy irq driver
This patch adds documentation to the mpc5200 interrupt controller
driver and cleans up some minor coding conventions.  It also moves the
contents of mpc52xx_pic.h into the driver proper (except for a small
common bit that is moved to the common mpc52xx.h) because the
information encoded there is not required by any other part of kernel
code.  Finally for code readability sake, the L2_OFFSET shift value
is removed because the code using it resolves to a noop.

Benjamin Herrenschmidt 9dce3ce5c5 powerpc/44x: 44x TLB doesn't need "Guarded" set for all pages
After discussing with chip designers, it appears that it's not
necessary to set G everywhere on 440 cores. The various core
errata related to prefetch should be sorted out by firmware by
disabling icache prefetching in CCR0. We add the workaround to
the kernel however just in case oooold firmwares don't do it.

This is valid for -all- 4xx core variants. Later ones hard wire
the absence of prefetch but it doesn't harm to clear the bits
in CCR0 (they should already be cleared anyway).

We still leave G=1 on the linear mapping for now, we need to
stop over-mapping RAM to be able to remove it.

Benjamin Herrenschmidt 64b3d0e812 powerpc/mm: Rework usage of _PAGE_COHERENT/NO_CACHE/GUARDED
Currently, we never set _PAGE_COHERENT in the PTEs, we just OR it in
in the hash code based on some CPU feature bit.  We also manipulate
_PAGE_NO_CACHE and _PAGE_GUARDED by hand in all sorts of places.

This changes the logic so that instead, the PTE now contains
_PAGE_COHERENT for all normal RAM pages thay have I = 0 on platforms
that need it.  The hash code clears it if the feature bit is not set.

It also adds some clean accessors to setup various valid combinations
of access flags and change various bits of code to use them instead.

This should help having the PTE actually containing the bit
combinations that we really want.

I also removed _PAGE_GUARDED from _PAGE_BASE on 44x and instead
set it explicitely from the TLB miss.  I will ultimately remove it
completely as it appears that it might not be needed after all
but in the meantime, having it in the TLB miss makes things a
lot easier.

Benjamin Herrenschmidt 7752035180 powerpc/mm: Runtime allocation of mmu context maps for nohash CPUs
This makes the MMU context code used for CPUs with no hash table
(except 603) dynamically allocate the various maps used to track
the state of contexts.

Only the main free map and CPU 0 stale map are allocated at boot
time.  Other CPU maps are allocated when those CPUs are brought up
and freed if they are unplugged.

This also moves the initialization of the MMU context management
slightly later during the boot process, which should be fine as
it's really only needed when userland if first started anyways.

Benjamin Herrenschmidt 2a4aca1144 powerpc/mm: Split low level tlb invalidate for nohash processors
Currently, the various forms of low level TLB invalidations are all
implemented in misc_32.S for 32-bit processors, in a fairly scary
mess of #ifdef's and with interesting duplication such as a whole
bunch of code for FSL _tlbie and _tlbia which are no longer used.

This moves things around such that _tlbie is now defined in
hash_low_32.S and is only used by the 32-bit hash code, and all
nohash CPUs use the various _tlbil_* forms that are now moved to
a new file, tlb_nohash_low.S.

I moved all the definitions for that stuff out of
include/asm/tlbflush.h as they are really internal mm stuff, into
mm/mmu_decl.h

The code should have no functional changes.  I kept some variants
inline for trivial forms on things like 40x and 8xx.

Benjamin Herrenschmidt f048aace29 powerpc/mm: Add SMP support to no-hash TLB handling
This commit moves the whole no-hash TLB handling out of line into a
new tlb_nohash.c file, and implements some basic SMP support using
IPIs and/or broadcast tlbivax instructions.

Note that I'm using local invalidations for D->I cache coherency.

At worst, if another processor is trying to execute the same and
has the old entry in its TLB, it will just take a fault and re-do
the TLB flush locally (it won't re-do the cache flush in any case).

Benjamin Herrenschmidt 2ca8cf7389 powerpc/mm: Rework context management for CPUs with no hash table
This reworks the context management code used by 4xx,8xx and
freescale BookE.  It adds support for SMP by implementing a
concept of stale context map to lazily flush the TLB on
processors where a context may have been invalidated.  This
also contains the ground work for generalizing such lazy TLB
flushing by just picking up a new PID and marking the old one
stale.  This will be implemented later.

This is a first implementation that uses a global spinlock.

Ideally, we should try to get at least the fast path (context ID
already assigned) lockless or limited to a per context lock,
but for now this will do.

I tried to keep the UP case reasonably simple to avoid adding
too much overhead to 8xx which does a lot of context stealing
since it effectively has only 16 PIDs available.

Brian King fecba96268 powerpc: Add reboot notifier to Collaborative Memory Manager
When running Active Memory Sharing, pages can get marked as
"loaned" with the hypervisor by the CMM driver. This state gets
cleared by the system firmware when rebooting the partition.
When using kexec to boot a new kernel, this state never gets
cleared and the hypervisor and CMM driver can get out of sync
with respect to the number of pages currently marked "loaned".
Fix this by adding a reboot notifier to the CMM driver to deflate
the balloon and mark all pages as active.

Brian King 2218108e18 powerpc: Disable Collaborative Memory Manager for kdump
When running Active Memory Sharing, the Collaborative Memory Manager
(CMM) may mark some pages as "loaned" with the hypervisor.
Periodically, the CMM will query the hypervisor for a loan request,
which is a single signed value.  When kexec'ing into a kdump kernel,
the CMM driver in the kdump kernel is not aware of the pages the
previous kernel had marked as "loaned", so the hypervisor and the CMM
driver are out of sync.  This results in the CMM driver getting a
negative loan request, which can then get treated as a large unsigned
value and can cause kdump to hang due to the CMM driver inflating too
large.  Since there really is no clean way for the CMM driver in the
kdump kernel to clean this up, simply disable CMM in the kdump kernel.
This fixes hangs we were seeing doing kdump with AMS.

Hendrik Brueckner 368c1e3249 hvc_console: Escape magic sysrq key
The ctrl-o (^O) is a common control key used by several applications,
such as vim, but hvc_console uses ^O as the magic-sysrq key.  This
commit allows users to send ^O to applications by pressing ^O twice
in succession.

To implement this, this commit introduces a check if ^O is pressed
again if the sysrq_pressed variable is already set.  In this case,
clear sysrq_pressed state and flip the ^O character to the tty.  (The
old behavior has always set "sysrq_pressed" if ^O has been entered,
and it has not flipped the ^O character to the tty.)

Marcel Holtmann aa6f3c6407 driver core: add newlines to debugging enabled/disabled messages
Both messages are missing the newline and thus dmesg output gets
scrambled.

Greg Kroah-Hartman 09a35ce00f xilinx_hwicap: remove improper wording in license statement
GPLv2 doesn't allow additional restrictions to be imposed on any
code, so this wording needs to be removed from these files.

Matthew Arnold 7c99200142 USB: add 5372:2303 to pl2303
This patch adds the "Superial" USB-Serial converter to pl2303 so that it
is detected, by the correct driver.  Adds the relevant vendor:product
(5372:2303) to the device tables in pl2303.c & pl2303.h.  The patch has
been tested against 2.6.24-22-generic.

Alan Stern 24c0996a6b USB: skip Set-Interface(0) if already in altsetting 0
When a driver unbinds from an interface, usbcore always sends a
Set-Interface request to reinstall altsetting 0.  Unforunately, quite
a few devices have buggy firmware that crashes when it receives this
request.

To avoid such problems, this patch (as1180) arranges to send the
Set-Interface request only when the interface is not already in
altsetting 0.

Phil Endecott 9a9fafb894 USB: fix comment about endianness of descriptors
This patch fixes a comment and clarifies the documentation about the
endianness of descriptors. The current policy is that descriptors will
be little-endian at the API even on big-endian systems; however the
/proc/bus/usb API predates this policy and presents descriptors with
some multibyte fields byte-swapped.
