* PM / AVR32: Use struct syscore_ops instead of sysdevs for PMRafael J. Wysocki2011-05-111-26/+12
| | | | | | | | | | | | | 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. Signed-off-by: Rafael J.

* avr32: add ATAG_BOARDINFOAndreas Bießmann2011-04-132-0/+24
| | | | | | | | | | | | | 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.

* don't check platform_get_irq's return value against zeroUwe Kleine-König2011-04-131-1/+1
| | | | | | | | | | | | | 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 305b3228f9ff4d59f49e6d34a7034d44ee8ce2f0 that changed the return value of platform_get_irq from 0 to -ENXIO on error.

* avr32: init cannot ignore signals sent by force_sig_info()Matt Fleming2011-04-131-22/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 623b0355d5b1 "[AVR32] Clean up exception handling code" but the code was deleted from arch/powerpc in November 2009 in commit a0592d42fe3e "powerpc: kill the obsolete code under is_global_init()" So catch up with powerpc and delete the bogus code.

* avr32: fix deadlock when reading clock list in debugfsOle Henrik Jahren2011-04-131-8/+16
| | | | | | | | | | | When writing out /sys/kernel/debug/at32ap_clk, clock list lock is being held while clk_get() is called. clk_get() attempts to take the same lock, which results in deadlock.

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
