2009-03-31parisc: use constants instead of numbers in assemblyHelge Deller1-4/+4
A few small fixups: * _PAGE_SIZE_ENCODING_DEFAULT is wrong here, as one might assume that it's possible to define the page size that way. This is wrong. Use 0 instead. * use constants instead of hardcoded numerical values in depi and extru while building the PFN out of the pte entry * use SHRREG instead of extru (iitlba expects the PFN at bits {7..26}) Still wondering why we can use the same register (pte) as extru source and target register, but it seems to work on PA1.1 and PA2.0...

2009-03-31parisc: fix usage of 32bit PTE page table entries on 32bit kernelsHelge Deller3-16/+19
This patch fixes a long outstanding bug on 32bit parisc linux kernels which prevented us from using 32bit PTE table entries (instead of 64bit entries of which 32bit were unused). The problem was caused by this assembler statement in the L2_ptep macro in arch/parisc/kernel/entry.S:447: EXTR \va,31-ASM_PGDIR_SHIFT,ASM_BITS_PER_PGD,\index which expanded to extrw,u r8,9,11,r1 and which has undefined behavior since the length value (11) extends beyond the leftmost bit (11-1 > 9). Interestingly PA2.0 processors seem to don't care and just zero-extend the value, while PA1.1 processors don't. Fix this problem by detecting an address space overflow with ASM_BITS_PER_PGD and adjusting it accordingly. To prevent such problems in the future, some compile time sanity checks in arch/parisc/mm/init.c were added. Since the page table now only consumes half of it's old size, we can use the freed memory to harmonize 32- and 64bit kernels and let both map 16MB for the initial page table.

2009-03-31arm: allow usage of string functions in linux/string.hRusty Russell1-1/+4
In introducing a trivial "strstarts()" function in linux/string.h, we hit: arch/arm/boot/compressed/misc.o: In function `strstarts': misc.c:(.text+0x368): undefined reference to `strlen' misc.c:(.text+0x378): undefined reference to `strncmp' This is because of "CFLAGS_misc.o := -Dstatic=" in the Makefile. "static inline strstarts(...)" becomes non-inline, and refers to the other string ops. The simplest workaround is to include asm/string.h. This makes sense anyway, since lib/string.c won't be linked against this so we can't use those functions anyway. Compile tested here.

2009-03-31proc 2/2: remove struct proc_dir_entry::ownerAlexey Dobriyan7-26/+3
Setting ->owner as done currently (pde->owner = THIS_MODULE) is racy as correctly noted at bug #12454. Someone can lookup entry with NULL ->owner, thus not pinning enything, and release it later resulting in module refcount underflow. We can keep ->owner and supply it at registration time like ->proc_fops and ->data. But this leaves ->owner as easy-manipulative field (just one C assignment) and somebody will forget to unpin previous/pin current module when switching ->owner. ->proc_fops is declared as "const" which should give some thoughts. ->read_proc/->write_proc were just fixed to not require ->owner for protection. rmmod'ed directories will be empty and return "." and ".." -- no harm. And directories with tricky enough readdir and lookup shouldn't be modular. We definitely don't want such modular code. Removing ->owner will also make PDE smaller. So, let's nuke it. Kudos to Jeff Layton for reminding about this, let's say, oversight. http://bugzilla.kernel.org/show_bug.cgi?id=12454 Signed-off-by: Alexey Dobriyan <adobriyan@gmail.com>

2009-03-30PM: Rework handling of interrupts during suspend-resumeRafael J. Wysocki1-4/+11
Use the functions introduced in by the previous patch, suspend_device_irqs(), resume_device_irqs() and check_wakeup_irqs(), to rework the handling of interrupts during suspend (hibernation) and resume. Namely, interrupts will only be disabled on the CPU right before suspending sysdevs, while device drivers will be prevented from receiving interrupts, with the help of the new helper function, before their "late" suspend callbacks run (and analogously during resume). In addition, since the device interrups are now disabled before the CPU has turned all interrupts off and the CPU will ACK the interrupts setting the IRQ_PENDING bit for them, check in sysdev_suspend() if any wake-up interrupts are pending and abort suspend if that's the case.

This patch removes the various CPU_AU1??? model constants in favor of a single CPU_ALCHEMY one. All currently existing Alchemy models are identical in terms of cpu core and cache size/organization. The parts of the mips kernel which need to know the exact CPU revision extract it from the c0_prid register already; and finally nothing else in-tree depends on those any more. Should a new variant with slightly different "company options" and/or "processor revision" bits in c0_prid appear, it will be supported immediately (minus an exact model string in cpuinfo).

2009-03-30MIPS: EMMA2RH: Use handle_edge_irq() handler for GPIO interruptsShinya Kuribayashi1-18/+10
EMMA's GPIO interrupts are latched by GPIO interrupt status register. In this case, we're encouraged to use handle_edge_irq() handler. The following changes are made along with replacing set_irq_chip() with set_irq_chip_and_handler_name(,,handle_edge_irq,"edge"): * Fix emma2rh_gpio_irq_ack not to disable interrupts With handle_edge_irq(), we're not expected to disable interrupts when chip->ack is served, so fix it accordingly. We also add a new emma2rh_gpio_irq_mask_ack() for chip->mask_ack operation, instead. * Remove emma2rh_gpio_irq_end(), as chip->end is no longer served.
