Michael S. Tsirkin 4673ca8eb3 lib: move GENERIC_IOMAP to lib/Kconfig
define GENERIC_IOMAP in a central location
instead of all architectures. This will be helpful
for the follow-up patch which makes it select
other configs. Code is also a bit shorter this way.

Johannes Berg 6e3e939f3b net: add wireless TX status socket option
The 802.1X EAPOL handshake hostapd does requires
knowing whether the frame was ack'ed by the peer.
Currently, we fudge this pretty badly by not even
transmitting the frame as a normal data frame but
injecting it with radiotap and getting the status
out of radiotap monitor as well. This is rather
complex, confuses users (mon.wlan0 presence) and
doesn't work with all hardware.

To get rid of that hack, introduce a real wifi TX
status option for data frame transmissions.

This works similar to the existing TX timestamping
in that it reflects the SKB back to the socket's
error queue with a SCM_WIFI_STATUS cmsg that has
an int indicating ACK status (0/1).

Since it is possible that at some point we will
want to have TX timestamping and wifi status in a
single errqueue SKB (there's little point in not
doing that), redefine SO_EE_ORIGIN_TIMESTAMPING
to SO_EE_ORIGIN_TXSTATUS which can collect more
than just the timestamp; keep the old constant
as an alias of course. Currently the internal APIs
don't make that possible, but it wouldn't be hard
to split them up in a way that makes it possible.

Thanks to Neil Horman for helping me figure out
the functions that add the control messages.

Greg Ungerer 144077ead4 m68k: merge the mmu and non-mmu traps.c files
The code for handling traps in the non-mmu case is a subset of the mmu
enabled case. Merge the non-mmu traps_no.c code back to a single traps.c.
There is actually no code mmu specific here at all, and the processor
specific code (for the more complex 68020/68030/68040/68060) is already
proplerly conditionaly used.

The format of console exception dump is a little different, but I don't

Greg Ungerer bc4f4ac2f0 m68k: move hardware vector setting from traps.c to its own file
Most of the trap.c code is general to all m68k arch members. But the code
it currently contains to set the hardware vector table is quite specific to
the 680x0 family. They can have the vector table at any address unlike
other family members (which either support only a single fixed address,
or a limited range of addresses). So lets move that code out to a new file,
vectors.c. This will make sharing the rest of the trap.c code easier and
cleaner.

Greg Ungerer 61619b1207 m68k: merge mmu and non-mmu include/asm/entry.h files
The changes in the mmu version of entry.h (entry_mm.h) and the non-mmu
version (entry_no.h) are not about the presence or use of an MMU at all.
The main changes are to support the ColdFire processors. The code for
trap entry and exit for all types of 68k processor outside coldfire is
the same.

So merge the files back to a single entry.h and share the common 68k
entry/exit code. Some changes are required for the non-mmu entry
handlers to adopt the differing macros for system call and interrupt
entry, but this is quite strait forward. The changes for the ColdFire
remove a couple of instructions for the separate a7 register case, and
are no worse for the older single a7 register case.

Greg Ungerer 281eff5322 m68k: merge mmu and non-mmu arch Makefiles
Most of the build logic is the same for the mmu and non-mmu m68k targets.
Merge the top level architecture Makefiles back into a single Makefile.

For the most part this is just adding the non-mmu processor types and
their specific cflags and other options into the mmu Makefile.

Note that all the BOARD setting logic that was in the non-mmu Makefile
is completely removed. It was no longer being used at all.

This has been build and run tested on ColdFire targets and ARAnyM.
It has been build tested on all the m68k defconfig targets using a
gcc-4.5.1 based toolchain.

Greg Ungerer 0e152d8050 m68k: reorganize Kconfig options to improve mmu/non-mmu selections
The current mmu and non-mmu Kconfig files can be merged to form
a more general selection of options. The current break up of options
is due to the simple brute force merge from the m68k and m68knommu
arch directories.

Many of the options are not at all specific to having the MMU enabled
or not. They are actually associated with a particular CPU type or
platform type.

Ultimately as we support all processors with the MMU disabled we need
many of these options to be selectable without the MMU option enabled.
And likewise some of the ColdFire processors, which currently are only
supported with the MMU disabled, do have MMU hardware, and will need
to have options selected on CPU type, not MMU disabled.

This patch removes the old mmu and non-mmu Kconfigs and instead breaks
up the configuration into four areas: cpu, machine, bus, devices.

The Kconfig.cpu lists all the options associated with selecting a CPU,
and includes options specific to each CPU type as well.

Kconfig.machine lists all options associated with selecting a machine
type. Almost always the machines selectable is restricted by the chosen
CPU.

Kconfig.bus contains options associated with selecting bus types on the
various machine types. That includes PCI bus, PCMCIA bus, etc.

Kconfig.devices contains options for drivers and driver associated
options.

Peter Turczak 89127ed381 m68knommu: fix problems with SPI/GPIO on ColdFire 520x
The problem has its root in the calculation of the set-port offsets (macro
MCFGPIO_SETR() in arch/m68k/include/asm/gpio.h), this assumes that all ports
have the same offset from the base port address (MCFGPIO_SETR) which is
defined in mcf520xsim.h as an alias of MCFGIO_PSETR_BUSCTL. Because the BUSCTL
and BE port do not have a set-register (see MCF5208 Reference Manual Page
13-10, Table 13-3) the offset calculations went wrong.

Because the BE and BUSCTL port do not seem useful in these parts, as they
lack a set register, I removed them and adapted the gpio chip bases which
are also used for the offset-calculations. Now both setting and resetting
the chip selects works as expected from userland and from the kernelspace.

Greg Ungerer f230e80b42 m68k: fix memcpy to unmatched/unaligned source and dest on 68000
The original 68000 processors cannot copy 16bit or larger quantities from
odd addresses. All newer members of the 68k family (including ColdFire)
can do this.

In the current memcpy implementation after trying to align the destination
address to a 16bit boundary if we end up with an odd source address we go
off and try to copy multi-byte quantities from it. This will trap on the
68000.

The only solution if we end with an odd source address is to byte wise
copy the whole memcpy region. We only need to do this if we are supporting
original 68000 processors.

Huang Ying df013ffb81 Add Kconfig option ARCH_HAVE_NMI_SAFE_CMPXCHG
cmpxchg() is widely used by lockless code, including NMI-safe lockless
code.  But on some architectures, the cmpxchg() implementation is not
NMI-safe, on these architectures the lockless code may need a
spin_trylock_irqsave() based implementation.

This patch adds a Kconfig option: ARCH_HAVE_NMI_SAFE_CMPXCHG, so that
NMI-safe lockless code can depend on it or provide different
implementation according to it.

On many architectures, cmpxchg is only NMI-safe for several specific
operand sizes. So, ARCH_HAVE_NMI_SAFE_CMPXCHG define in this patch
only guarantees cmpxchg is NMI-safe for sizeof(unsigned long).

Michael Schmitz 217bbd8188 m68k/atari: Reserve some ST-RAM early on for device buffer use
Based on an original patch from Michael Schmitz:

Because mem_init() is now called before device init, devices that rely on
ST-RAM may find all ST-RAM already allocated to other users by the time
device init happens. In particular, a large initrd RAM disk may use up
enough of ST-RAM to cause atari_stram_alloc() to resort to
__get_dma_pages() allocation.

In the current state of Atari memory management, all of RAM is marked
DMA capable, so __get_dma_pages() may well return RAM that is not in actual
fact DMA capable. Using this for frame buffer or SCSI DMA buffer causes
subtle failure.

The ST-RAM allocator has been changed to allocate memory from a pool of
reserved ST-RAM of configurable size, set aside on ST-RAM init (i.e.
before mem_init()). As long as this pool is not exhausted, allocation of
real ST-RAM can be guaranteed.

Other changes:
  - Replace the custom allocator in the ST-RAM pool by the existing allocator
    in the resource subsystem,
  - Remove mem_init_done and its hook, as memory init is now done before
    device init,
  - Remove /proc/stram, as ST-RAM usage now shows up under /proc/iomem, e.g.

	005f2000-006f1fff : ST-RAM Pool
	  005f2000-0063dfff : atafb
	  0063e000-00641fff : ataflop

Fix the remaining atomic operations to be clean for ColdFire processors.

Greg Ungerer f3c23a28ac m68k: use CPU_HAS_NO_BITFIELDS for signal functions
When reworking bitops.h to be clean for all processor types we introduced
a CONFIG_CPU_HAS_NO_BITFIELDS define to signal whether this processor type
supported the bit field instructions. The ARCH_SIG_BITOPS functions for
m68k use these instruction types. We should base the use of these functions
(or the generic versions) on the CONFIG_CPU_HAS_NO_BITFIELDS define.

Greg Ungerer 7c946199cd m68k: merge and clean up delay.h files
The real difference between the mmu and non-mmu varients of the delay.h
files has nothing to do with having an mmu or not. It is processor family
differences that means slightly different code. Merge the delay_mm.h and
delay_no.h files back into a single file.

The primarly difference we need to deal with is whether the processor
supports a 32bit * 32bit -> 64bit multiply. Without it we need to do some
shift scaling as well as use a 32bit * 32bit -> 32bit multiply. If building
for a multi-CPU type kernel then we must use the simpler mult/shift scaling.

This version of delay code allows the CPU32 family to use a 64bit mul,
since it supports this instruction, the old code did not.

The changes use macros where appropriate to try and optimize constant sized
udelay times. And it removes the use of a fixed lib function for the non-mmu
case. Code size on typical kernel configurations is similar, or only larger
by a few tens of bytes.

Also removed the unused muldiv() code from delay_mm.h.

Build and run tested on ColdFire and ARAnyM. Build tested only on 68328
and 68360 (CPU32).

Greg Ungerer 622e9472dd m68knommu: correctly use trap_init
Currently trap_init() is an empty function for m68knommu. Instead
the vectors are being setup as part of the IRQ initialization.
This is inconsistent with m68k and other architectures.

Change the local init_vectors() to be trap_init(), and init the
vectors at the correct time during startup. This will help merge of
m68k and m68knommu trap code in the furture.

Greg Ungerer 171d809df1 m68k: merge mmu and non-mmu bitops.h
The following patch merges the mmu and non-mmu versions of the m68k
bitops.h files. Now there is a good deal of difference between the two
files, but none of it is actually an mmu specific difference. It is
all about the specific m68k/coldfire varient we are targeting. So it
makes an awful lot of sense to merge these into a single bitops.h.

There is a number of ways I can see to factor this code. The approach
I have taken here is to keep the various versions of each macro/function
type together. This means that there is some ifdefery with each to handle
each CPU type.

I have added some comments in a couple of appropriate places to try
and make it clear what the differences we are dealing with are.
Specifically the instruction and addressing mode differences we have
to deal with.

The merged form keeps the same underlying optimizations for each CPU
type for all the general bit clear/set/change and find bit operations.
It does switch to using the generic le operations though, instead of
any local varients.

Build tested on ColdFire, 68328, 68360 (which is cpu32) and 68020+.
Run tested on ColdFire and ARAnyM.

The non-MMU m68k targets can use the same asm/system.h as the MMU

The assembly support code for the non-MMU resume functions needs to
be modified to match the now common switch_to() macro. Specifically
this means correctly saving and restoring the status flags in the case
of the ColdFire resume, and some reordering of the code to not use

Greg Ungerer 734c3ce3bd m68k: use kernel processor defines for conditional optimizations
Older m68k-linux compilers will include pre-defined symbols that
confuse what processor it is being targeted for. For example gcc-4.1.2
will pre-define __mc68020__ even if you specify the target processor
as -m68000 on the gcc command line. Newer versions of gcc have this
corrected.

In a few places the m68k code uses defined(__mc68020__) for optimizations
that include instructions that are specific to the CPU 68020 and above.
When compiling with older compilers this will be true even when we have
selected to compile for the older 68000 processors.

Switch to using the kernel processor defines, CONFIG_M68020 and friends.

* setns:
  ns: Wire up the setns system call

Done as a merge to make it easier to fix up conflicts in arm due to
addition of sendmmsg system call
2011-05-28 10:51:01 -07:00
Eric W. Biederman 7b21fddd08 ns: Wire up the setns system call
32bit and 64bit on x86 are tested and working.  The rest I have looked
at closely and I can't find any problems.

setns is an easy system call to wire up.  It just takes two ints so I
don't expect any weird architecture porting problems.

While doing this I have noticed that we have some architectures that are
very slow to get new system calls.  cris seems to be the slowest where
the last system calls wired up were preadv and pwritev.  avr32 is weird
in that recvmmsg was wired up but never declared in unistd.h.  frv is
behind with perf_event_open being the last syscall wired up.  On h8300
the last system call wired up was epoll_wait.  On m32r the last system
call wired up was fallocate.  mn10300 has recvmmsg as the last system
call wired up.  The rest seem to at least have syncfs wired up which was
new in the 2.6.39.

v2: Most of the architecture support added by Daniel Lezcano <dlezcano@fr.ibm.com>
v3: ported to v2.6.36-rc4 by: Eric W. Biederman <ebiederm@xmission.com>
v4: Moved wiring up of the system call to another patch
v5: ported to v2.6.39-rc6
v6: rebased onto parisc-next and net-next to avoid syscall  conflicts.
v7: ported to Linus's latest post 2.6.39 tree.

The style that we normally use in asm-generic is to test the macro itself
for existence, so in asm-generic, do:

	#ifndef find_next_zero_bit_le
	extern unsigned long find_next_zero_bit_le(const void *addr,
		unsigned long size, unsigned long offset);
	#endif

and in the architectures, write

	static inline unsigned long find_next_zero_bit_le(const void *addr,
		unsigned long size, unsigned long offset)
	#define find_next_zero_bit_le find_next_zero_bit_le

This adds the #define for each of the optimized find bitops in the
architectures.

We don't need an arch/m68k/lib/checksum.c wrapper to include the correct
mmu or non-mmu version of the checksum code. Let the Makefile just build
the appropriate one.

Greg Ungerer 66d83ab32a m68k: remove duplicate memcpy() implementation
Merging the mmu and non-mmu directories we ended up with duplicate
implementations of memcpy(). One is a little more optimized for the
>= 68020 case, but that can easily be inserted into a single
implementation of memcpy(). Clean up the exporting of this symbol
too, otherwise we end up exporting it twice on a no-mmu build.

Steven Rostedt a2d063ac21 extable, core_kernel_data(): Make sure all archs define _sdata
A new utility function (core_kernel_data()) is used to determine if a
passed in address is part of core kernel data or not. It may or may not
return true for RO data, but this utility must work for RW data.

Thus both _sdata and _edata must be defined and continuous,
without .init sections that may later be freed and replaced by
volatile memory (memory that can be freed).

This utility function is used to determine if data is safe from
ever being freed. Thus it should return true for all RW global
data that is not in a module or has been allocated, or false
otherwise.

Also change core_kernel_data() back to the more precise _sdata condition
and document the function.

Geert Uytterhoeven f82a519f12 m68k: bitops - Never step beyond the end of the bitmap
find_next bitops on m68k (find_next_zero_bit, find_next_bit, and
find_next_bit_le) may cause out of bounds memory access
when the bitmap size in bits % 32 != 0 and offset (the bitnumber
to start searching at) is very close to the bitmap size.

For example,

       unsigned long bitmap[2] = { 0, 0 };
       find_next_bit(bitmap, 63, 62);

1. find_next_bit() tries to find any set bits in bitmap[1],
   but no bits set.

2. Then find_first_bit(bimap + 2, -1)

3. Unfortunately find_first_bit() takes unsigned int as the size argument.

4. find_first_bit will access bitmap[2~] until it find any set bits.

Add missing tests for stepping beyond the end of the bitmap to all
find_{first,next}_*() functions, and make sure they never return a value
larger than the bitmap size.

Michael Schmitz 4aac0b4815 m68k/mm: Set all online nodes in N_NORMAL_MEMORY
For m68k, N_NORMAL_MEMORY represents all nodes that have present memory
since it does not support HIGHMEM.  This patch sets the bit at the time
node_present_pages has been set by free_area_init_node.
At the time the node is brought online, the node state would have to be
done unconditionally since information about present memory has not yet
been recorded.

If N_NORMAL_MEMORY is not accurate, slub may encounter errors since it
uses this nodemask to setup per-cache kmem_cache_node data structures.

This pach is an alternative to the one proposed by David Rientjes
<rientjes@google.com> attempting to set node state immediately when
bringing the node online.

Greg Ungerer 66d857b08b m68k: merge m68k and m68knommu arch directories
There is a lot of common code that could be shared between the m68k
and m68knommu arch branches. It makes sense to merge the two branches
into a single directory structure so that we can more easily share
that common code.

This is a brute force merge, based on a script from Stephen King
<sfking@fdwdc.com>, which was originally written by Arnd Bergmann
<arnd@arndb.de>.

> The script was inspired by the script Sam Ravnborg used to merge the
> includes from m68knommu. For those files common to both arches but
> differing in content, the m68k version of the file is renamed to
> <file>_mm.<ext> and the m68knommu version of the file is moved into the

> wrapper file <file>.<ext> is used to select between the two version. Files
> that are common to both but don't differ are removed from the m68knommu
> tree and files and directories that are unique to the m68knommu tree are
> moved to the m68k tree. Finally, the arch/m68knommu tree is removed.
>
> To select between the the versions of the files, the wrapper uses
>
> #ifdef CONFIG_MMU
> #include <file>_mm.<ext>
> #else
> #include <file>_no.<ext>
> #endif

On top of this file merge I have done a simplistic merge of m68k and
m68knommu Kconfig, which primarily attempts to keep existing options and
menus in place. Other than a handful of options being moved it produces
identical .config outputs on m68k and m68knommu targets I tested it on.

With this in place there is now quite a bit of scope for merge cleanups
in future patches.
