Hans-Christian Egtvedt c162755491 avr32: make intc_resume() return void to conform to syscore_ops
This patch removes the unneeded, and now wrong, return 0 from intc_resume() and
lets the function return void instead. This matches the resume callback in
struct syscore_ops.

Nicolas Ferre 3000f0077a avr32: add some more at91 to cpu.h definition
Somme common drivers will need those at91 cpu_is_xxx() definitions.
Those definitions are already in Linus' tree so if we want to use them
in common drivers, we will need them in AVR32 cpu.h file.

Linus Torvalds 571503e100 Merge branch 'setns'
* 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.

Akinobu Mita a2812e1783 arch: add #define for each of optimized find bitops
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.

Rafael J. Wysocki f25f4f522a PM / AVR32: Use struct syscore_ops instead of sysdevs for PM
Convert some AVR32 architecture's code to using struct syscore_ops
objects for power management instead of sysdev classes and sysdevs.

This simplifies the code and reduces the kernel's memory footprint.
It also is necessary for removing sysdevs from the kernel entirely in
the future.

Andreas Bießmann 24a1a47562 avr32: add ATAG_BOARDINFO
The ATAG_BOARDINFO is intended to hand over the information
bd->bi_board_number from u-boot to the kernel.

This piece of information can be used to implement some kind of board
identification while booting the kernel. Therefore it is placed in .initdata
section and can be accessed via the new symbol board_number only while
initializing the kernel.

Uwe Kleine-König c7d876321f don't check platform_get_irq's return value against zero
platform_get_irq returns -ENXIO on failure, so !int_irq was probably
always true.  Better use (int)int_irq <= 0.  Note that a return value of
zero is still handled as error even though this could mean irq0.

This is a followup to 305b3228f9 that
changed the return value of platform_get_irq from 0 to -ENXIO on error.

Matt Fleming 9f0d15aac9 avr32: init cannot ignore signals sent by force_sig_info()
We can delete the code that checks to see if we're sending an ignored
signal to init because force_sig_info() already handles this case.
force_sig_info() will kill init even if the signal handler is SIG_DFL
and the scenario described in the comment where init might "generate
the same exception over and over again" cannot occur (force_sig_info()
clears SIGNAL_UNKILLABLE to ensure that init will die).

Also, the use of is_global_init() is not correct in the multhreaded
case, as Oleg Nesterov explains,

	"is_global_init() is not right in theory, /sbin/init can be
	multithreaded. And, this doesn't cover the sub-namespace
	inits... I'd suggest to check SIGNAL_UNKILLABLE, but looking
	closer I think you can simply remove this code."

It seems this code was copied from arch/powerpc in March 2007 in commit

  623b0355d5 "[AVR32] Clean up exception handling code"

but the code was deleted from arch/powerpc in November 2009 in commit

  a0592d42fe "powerpc: kill the obsolete code under is_global_init()"

So catch up with powerpc and delete the bogus code.

Akinobu Mita 61f2e7b0f4 bitops: remove minix bitops from asm/bitops.h
minix bit operations are only used by minix filesystem and useless by
other modules.  Because byte order of inode and block bitmaps is different
on each architecture like below:

m68k:
	big-endian 16bit indexed bitmaps

h8300, microblaze, s390, sparc, m68knommu:
	big-endian 32 or 64bit indexed bitmaps

m32r, mips, sh, xtensa:
	big-endian 32 or 64bit indexed bitmaps for big-endian mode
	little-endian bitmaps for little-endian mode

Others:
	little-endian bitmaps

In order to move minix bit operations from asm/bitops.h to architecture
independent code in minix filesystem, this provides two config options.

CONFIG_MINIX_FS_BIG_ENDIAN_16BIT_INDEXED is only selected by m68k.
CONFIG_MINIX_FS_NATIVE_ENDIAN is selected by the architectures which use
native byte order bitmaps (h8300, microblaze, s390, sparc, m68knommu,
m32r, mips, sh, xtensa).  The architectures which always use little-endian
bitmaps do not select these options.

Finally, we can remove minix bit operations from asm/bitops.h for all
architectures.

All architectures can use the common dma_addr_t typedef now. We can
remove the arch specific dma_addr_t.

Now that the dw_dmac DMA driver supports configurable Flow Controller, source

David Rientjes 6a108a14fa kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERT
The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option
is used to configure any non-standard kernel with a much larger scope than
only small devices.

This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes
references to the option throughout the kernel.  A new CONFIG_EMBEDDED
option is added that automatically selects CONFIG_EXPERT when enabled and
can be used in the future to isolate options that should only be
considered for embedded systems (RISC architectures, SLOB, etc).

Calling the option "EXPERT" more accurately represents its intention: only
expert users who understand the impact of the configuration changes they
are making should enable it.

Hans-Christian Egtvedt 992a88b62c avr32: make architecture sys_clone prototype match asm-generic prototype
This patch will fix the arguments to the architecture sys_clone() function to
match the asm-generic/syscalls.h prototype. In the same go remove the
architecture specific prototype for the same function.

The sys_clone() function is only called from assembly, hence the argument types
were not having any affect.
