2007-05-07slab: introduce kreallocPekka Enberg3-3/+84
This introduce krealloc() that reallocates memory while keeping the contents unchanged. The allocator avoids reallocation if the new size fits the currently used cache. I also added a simple non-optimized version for mm/slob.c for compatibility.

2007-05-07Revert "[PATCH] x86: __pa and __pa_symbol address space separation"Linus Torvalds10-58/+66
This was broken. It adds complexity, for no good reason. Rather than separate __pa() and __pa_symbol(), we should deprecate __pa_symbol(), and preferably __pa() too - and just use "virt_to_phys()" instead, which is more readable and has nicer semantics. However, right now, just undo the separation, and make __pa_symbol() be the exact same as __pa(). That fixes the bugs this patch introduced, and we can do the fairly obvious cleanups later. Do the new __phys_addr() function (which is now the actual workhorse for the unified __pa()/__pa_symbol()) as a real external function, that way all the potential issues with compile/link-time optimizations of constant symbol addresses go away, and we can also, if we choose to, add more sanity-checking of the argument.

Start using faster versions of the ide_dma_end() and ide_dma_test_irq() methods for the PCI0646U and newer chips that have the duplicate interrupt status bits in the I/O mapped MRDMODE register, determing what methods to use at the driver load time.

While at it, also perform the following cleanups: - don't print extra newline before the first controller's dump; - correct the chipset names (from CMDxxx to PCI-xxx) - don't read from the registers which aren't used for dump; - better align the table column sizes; - rework UltraDMA mode dump code; - remove PIO mode dump code that has never been finished; - remove the duplicate interrupt status (the MRDMODE register bits mirror those those in the CFR and ARTTIM23 registers) and fold the dump into single line; - correct the style of the ?: operators...

2007-05-05cmd64x: fix multiword and remove single-word DMA supportSergei Shtylyov1-131/+117
Fix the multiword DMA and drop the single-word DMA support (which nobody will miss, I think). In order to do it, a number of changes was necessary: - rename program_drive_counts() to program_cycle_times(), pass to it cycle's total/active times instead of the clock counts, and convert them into the active/recovery clocks there instead of cmd64x_tune_pio() -- this causes quantize_timing() to also move; - contrarywise, move all the code handling the address setup timing into cmd64x_tune_pio(), so that setting MWDMA mode wouldn't change address setup; - remove from the speedproc() method the bogus code pretending to set the DMA timings by twiddling bits in the BMIDE status register, handle setting MWDMA by just calling program_cycle_times(); while at it, improve the style of that whole switch statement; - stop fiddling with the DMA capable bits in the speedproc() method -- they do not enable DMA, and are properly dealt with by the dma_host_{on,off} methods; - don't set hwif->swdma_mask in the init_hwif() method anymore. In addition to those changes, do the following: - in cmd64x_tune_pio(), when writing to ARTTIM23 register preserve the interrupt status bit, eliminate local_irq_{save|restore}() around this code as there's *no* actual race with the interrupt handler, and move cmdprintk() to a more fitting place -- after ide_get_best_pio_mode() call; - make {arttim|drwtim}_regs arrays single-dimensional, indexed with drive->dn; - rename {setup|recovery}_counts[] into more fitting {setup|recovery}_values[]; - in the speedproc() method, get rid of the duplicate reads/writes from/to the UDIDETCRx registers and of the extra variable used to store the transfer mode value after filtering, use another method of determining master/slave drive, and cleanup useless parens; - beautify cmdprintk() output here and there. While at it, remove meaningless comment about the driver being used only on UltraSPARC and long non-relevant RCS tag. :-) Signed-off-by: Sergei Shtylyov <sshtylyov@ru.mvista.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

Defer writing the DMA timings to the chip registers until DMA is really turned on (and do not enable IORDY for DMA). Remove unneeded code from the init_hwif() method, improve its overall looks.

2007-05-05sl82c105: rework PIO support (take 2)Sergei Shtylyov2-59/+41
Get rid of the 'pio_speed' member of 'ide_drive_t' that was only used by this driver by storing the PIO mode timings in the 'drive_data' instead -- this allows us to greatly simplify the process of "reloading" of the chip's timing register and do it right in sl82c150_dma_off_quietly() and to get rid of two extra arguments to config_for_pio() -- which got renamed to sl82c105_tune_pio() and now returns a PIO mode selected, with ide_config_drive_speed() call moved into the tuneproc() method, now called sl82c105_tune_drive() with the code to set drive's 'io_32bit' and 'unmask' flags in its turn moved to its proper place in the init_hwif() method. Also, while at it, rename get_timing_sl82c105() into get_pio_timings() and get rid of the code in it clamping cycle counts to 32 which was both incorrect and never executed anyway...

2007-05-05[ARM] mm 10: allow memory type to be specified with ioremapRussell King9-48/+54
__ioremap() took a set of page table flags (specifically the cacheable and bufferable bits) to control the mapping type. However, with the advent of ARMv6, this is far too limited. Replace the page table flags with a memory type index, so that the desired attributes can be selected from the mem_type table. Finally, to prevent silent miscompilation due to the differing arguments, rename the __ioremap() and __ioremap_pfn() functions. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2007-05-05[TG3]: Eliminate the TG3_FLAG_5701_REG_WRITE_BUG flag.Matt Carlson2-13/+12
This patch removes the use of the TG3_FLAG_5701_REG_WRITE_BUG flag. It's logic is only used to set a function pointer and thus the logic can be collapsed and the flag removed.

2007-05-05[TG3]: Remove reset during MAC address changes.Michael Chan1-17/+18
The reset was added a while back so that ASF could re-init whatever MAC address it wanted to use after the MAC address was changed. Instead of resetting, we can just keep MAC address 1 unchanged during MAC address changes if MAC address 1 is different from MAC address 0. This fixes 2 problems: 1. Bonding calls set_mac_address in contexts that cannot sleep. It no longer sleeps with the chip reset removed. 2. When ASF shares the same MAC address as the NIC, it needs to always do that even when the MAC address is changed. Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S.

2007-05-05[TG3]: Improve NVRAM sizing.Matt Carlson1-16/+23
This patch changes the NVRAM sizing procedure so that the driver can take advantage of devices with 1:1 NVRAM strapping configurations. This is useful in cases where the traditional NVRAM sizing method fails. In the event that the flash size cannot be determined, the largest known NVRAM size is used. The patch also removes support for 5755 NVRAM devices that are not supported by Broadcom and adds explicit sizing for this device.

2007-05-05[TG3]: Fix TSO bugs.Matt Carlson1-6/+3
1. Remove the check for skb->len greater than MTU when doing TSO. When the destination has a smaller MSS than the source, a TSO packet may be smaller than the MTU and we still need to process it as a TSO packet. 2. On 5705A3 devices with TSO enabled, the DMA engine can hang due to a hardware bug. This patch avoids the hanging condition by reducing the DMA burst size.
