Some archs want to print extra information for certain irq_chips which is per irq and not per chip. Allow them to provide a chip callback to print the chip name and the extra information. PowerPC wants to print the LEVEL/EDGE type information. Make it configurable. Signed-off-by:Thomas Gleixner <tglx@linutronix.de>

For the time being can we fix up the ep93xx gpio code with the amended patch below. It keeps the information that the pin is also configured as an interrupt and cleans the code up a bit. [ tglx: Rebased it on the removal patch ] Signed-off-by:

gpiolib plus two gpio implementations in arm fiddle in the guts of irq_desc in a racy and buggy way. Remove the stuff. I already told the gpio folks that we can provide that information in a proper way if necessary. Signed-off-by:

No need to fiddle in irq_desc. The trigger mask can be written back into irq_data. Return IRQ_SET_MASK_OK_NOCOPY, so the generic code wont overwrite it again. Signed-off-by: -

Some irq_set_type() callbacks need to change the chip and the handler when the trigger mode changes. We have already a (misnomed) setter function for the handler which can be called from irq_set_type(). Provide one which allows to set chip and name as well. Put the misnomed function under the COMPAT switch and provide a replacement. Signed-off-by: -

Some irq chips need to call genirq functions for nested chips from their callbacks. That upsets lockdep. So they need to set a different lock class for those nested chips. Provide a helper function to avoid open access to irq_desc. Signed-off-by: -

I'm not sure why the read-only data section is excluded from the report, it seems as relevant as the other data sections (b and d). I've stripped the symbols starting with __mod_ as they can have their names dynamically generated and thus comparison between binaries is not possible. Signed-off-by:

Instead of always creating a huge (268K) deflate_workspace with the maximum compression parameters (windowBits=15, memLevel=8), allow the caller to obtain a smaller workspace by specifying smaller parameter values. For example, when capturing oops and panic reports to a medium with limited capacity, such as NVRAM, compression may be the only way to capture the whole report. In this case, a small workspace (24K works fine) is a win, whether you allocate the workspace when you need it (i.e., during an oops or panic) or at boot time. I've verified that this patch works with all accepted values of windowBits (positive and negative), memLevel, and compression level. Signed-off-by:

The test program below will hang because io_getevents() uses add_wait_queue_exclusive(), which means the wake_up() in io_destroy() only wakes up one of the threads. Fix this by using wake_up_all() in the aio code paths where we want to make sure no one gets stuck. // t.c -- compile with gcc -lpthread -laio t.c #include <libaio.h> #include <pthread.h> #include <stdio.h> #include <unistd.h> static const int nthr = 2; void *getev(void *ctx) { struct io_event ev; io_getevents(ctx, 1, 1, &ev, NULL); printf("io_getevents returned\n"); return NULL; } int main(int argc, char *argv[]) { io_context_t ctx = 0; pthread_t thread[nthr]; int i; io_setup(1024, &ctx); for (i = 0; i < nthr; ++i) pthread_create(&thread[i], NULL, getev, ctx); sleep(1); io_destroy(ctx); for (i = 0; i < nthr; ++i) pthread_join(thread[i], NULL); return 0; } Signed-off-by:Roland Dreier <roland@purestorage.com> Reviewed-by:

ADFS (FileCore) storage complies with the RISC OS filetype specification (12 bits of file type information is stored in the file load address, rather than using a file extension). The existing driver largely ignores this information and does not present it to the end user. It is desirable that stored filetypes be made visible to the end user to facilitate a precise copy of data and metadata from a hard disc (or image thereof) into a RISC OS emulator (such as RPCEmu) or to a network share which can be accessed by real Acorn systems. This patch implements a per-mount filetype suffix option (use -o ftsuffix=1) to present any filetype as a ,xyz hexadecimal suffix on each file. This type suffix is compatible with that used by RISC OS systems that access network servers using NFS client software and by RPCemu's host filing system. Signed-off-by:

ADFS (FileCore) storage complies with the RISC OS timestamp specification (40-bit centiseconds since 01 Jan 1900 00:00:00). It is desirable that stored timestamp precision be maintained to facilitate a precise copy of data and metadata from a hard disc (or image thereof) into a RISC OS emulator (such as RPCEmu). This patch implements a full-precision conversion from ADFS to Unix timestamp as the existing driver, for ease of calculation with old 32-bit compilers, uses the common trick of shifting the 40-bits representing centiseconds around into 32-bits representing seconds thereby losing precision.

Kernel crashes in fs/adfs module when accessing directories with a large number of objects on mounted Acorn ADFS E+/F+ format discs (or images) as the existing code writes off the end of the fixed array of struct buffer_head pointers. Additionally, each directory access that didn't crash would leak a buffer as nr_buffers was not adjusted correctly for E+/F+ discs (was always left as one less than required). The patch fixes this by allocating a dynamically-sized set of struct buffer_head pointers if necessary for the E+/F+ case (many directories still do in fact fit in 2048 bytes) and sets the correct nr_buffers so that all buffers are released. Addresses https://bugzilla.kernel.org/show_bug.cgi?id=26072 Tested by tar'ing the contents of my RISC PC's E+ format 20Gb HDD which contains a number of large directories that previously crashed the kernel.

Not all 64-bit systems require ISA-style DMA, so allow it to be configurable. x86 utilizes the generic ISA DMA allocator from kernel/dma.c, so require it only when CONFIG_ISA_DMA_API is enabled. Disabling CONFIG_ISA_DMA_API is dependent on x86_64 since those machines do not have ISA slots and benefit the most from disabling the option (and on CONFIG_EXPERT as required by H. Peter Anvin). When disabled, this also avoids declaring claim_dma_lock(), release_dma_lock(), request_dma(), and free_dma() since those interfaces will no longer be provided. Signed-off-by:
