- Diagnose 8 needs a response buffer below 2GB real storage. As the caller cannot always allocate the buffer with GFP_DMA the best solution is to rewrite cpcmd to use a bounce buffer if necessary. The old function was renamed to __cpcmd and can be called if appropriate. The early boot code does not provide kmalloc but need cpcmd functionality. These places have been converted to use __cpcmd, as the init code and data are below 2GB. - In case of an 31 bit system, cpcmd is defined as __cpcmd. - EXPORT_SYMBOL(cpcmd) moved into cpcmd.c - some whitespace fixes in cpcmd.[c/h] Signed-off-by:

This patch fixes 2 SMP deadlocks. The first is that mv64x60_read() was returning before the unlock. The second was mv64x60_modify() locks the spin lock and calls mv64x60_read() and mv64x60_write() which also lock the same spin lock. Signed-Off-By:

include/asm-ppc/rwsem.h has '#ifdef RWSEM_DEBUG' but RWSEM_DEBUG is always defined (as 0) in include/linux/rwsem.h. The #ifdef's should be #if's. This also brings the ppc usage in line with the the other architectures. Signed-off-by:

Since acpi_cpufreq_resume and speedstep_resume appear to return 0 upon success, it seems like the attached patch is what the desired behavior would be. Otherwise, cpufreq_resume() always prints an error and exits early if using a cpufreq_driver that supports resume. Signed-off-by:

avma1_cs detect routine for AVM A1 based PCMCIA cards has its "outb" parameters inverted - switch to "byteout" define to be conformant with the rest of the driver, fixing the order. This was noticed on PPC, which triggers an MCE in case of invalid IO port access, which is not the case on x86. Signed-off-by:

<linux/prio_tree.h> is unsafe for inclusion by userland apps, but it is in the userland-exposed portion of <linux/fs.h>. It's only needed in the __KERNEL__ protected portion of the file, so move the #include down to there. lmbench-2.0.4 runs into this issue in 'flushdisk'. Signed-off-by:

Fix some bugs in device-mapper handling of 64-bit values, replacing dm_div_up() and dm_round_up() inlines with macros and removing some avoidable divisions of 64-bit numbers. The mirror region size is the granularity used to manage and monitor the data copying, typically 512KB, so 32 bits (of sectors) should be plenty to hold this. Taken together with the two earlier patches: "fix TB stripe data corruption" (a missing cast) and "stripe_width should be sector_t", I've now had 3 independent reports that this fixes device-mapper for devices with large stripes. Still awaiting test results for dm-crypt and dm-raid1. Signed-Off-By:

Not that low-level code really tends to care, but since loff_t is a signed 64-bit entity and size_t is unsigned (and potentially 64-bit), mixing the two isn't very well-defined..

The actual user copy will do them too, but only for the range that ends up being actually copied. That hides bugs when the range has been clamped by file size or other issues.

In __ide_do_rw_disk(), ide_started used to be returned blindly after issusing PIO write. This can cause hang if pre_task_out_intr() returns ide_stopped due to failed ide_wait_stat() test. Fixed to pass the return value of pre_task_out_intr(). Signed-off-by:

In drivers/ide/pci/piix.[hc], init_setup_piix() is defined and used but only one init_setup function is defined and no demultiplexing is done using init_setup callback. As other drivers call ide_setup_pci_device() directly in such cases, this patch removes init_setup_piix() and makes piix_init_one() call ide_setup_pci_device() directly. Signed-off-by:
