The current computation, introduced with f12a15be63, of FSEC_PER_SEC using
the multiplication of (FSEC_PER_NSEC * NSEC_PER_SEC) is performed only
with 32bit integers on small machines, resulting in an overflow and a
*very* short intervals being programmed. An interrupt storm follows.
Note that we also have to specify FSEC_PER_SEC as being long long to
overcome the same limitations.

Don't try and #include <linux/slab.h> in lib/inflate.c from the bootloader code
as linux/slab.h hauls in function defs that aren't available in the bootloader
code and may also haul in conflicting functions.
To fix this, make the inclusion of linux/slab.h contingent on NO_INFLATE_MALLOC
as are the usages of kmalloc() and kfree().

To keep panic_timeout accuracy when running under a hypervisor, the
current implementation only spins on long time (1 second) calls to mdelay.
That brings a good effect, but the problem is the keyboard LEDs don't
blink at all on that situation.
This patch changes to call to panic_blink_enter() between every mdelay and
keeps blinking in spite of long spin timer mode.
The time to call to mdelay is now 100ms. Even this change will keep
panic_timeout accuracy enough when running under a hypervisor.

Architectures implement dma_is_consistent() in different ways (some
misinterpret the definition of API in DMA-API.txt). So it hasn't been so
useful for drivers. We have only one user of the API in tree. Unlikely
out-of-tree drivers use the API.
Even if we fix dma_is_consistent() in some architectures, it doesn't look
useful at all. It was invented long ago for some old systems that can't
allocate coherent memory at all. It's better to export only APIs that are
definitely necessary for drivers.
Let's remove this API.

dma_get_cache_alignment returns the minimum DMA alignment. Architectures
defines it as ARCH_DMA_MINALIGN (formally ARCH_KMALLOC_MINALIGN). So we
can unify dma_get_cache_alignment implementations.
Note that some architectures implement dma_get_cache_alignment wrongly.
dma_get_cache_alignment() should return the minimum DMA alignment. So
fully-coherent architectures should return 1. This patch also fixes this
issue.

Now each architecture has the own dma_get_cache_alignment implementation.
dma_get_cache_alignment returns the minimum DMA alignment. Architectures
define it as ARCH_KMALLOC_MINALIGN (it's used to make sure that malloc'ed
buffer is DMA-safe; the buffer doesn't share a cache with the others). So
we can unify dma_get_cache_alignment implementations.
This patch:
dma_get_cache_alignment() needs to know if an architecture defines
ARCH_KMALLOC_MINALIGN or not (needs to know if architecture has DMA
alignment restriction). However, slab.h define ARCH_KMALLOC_MINALIGN if
architectures doesn't define it.
Let's rename ARCH_KMALLOC_MINALIGN to ARCH_DMA_MINALIGN.
ARCH_KMALLOC_MINALIGN is used only in the internals of slab/slob/slub
(except for crypto).

Subject: [PATCH 12/19] ARM: cam60: don't use __init for cam60_spi_{flash_platform_data,partitions}
Date: Thu, 5 Aug 2010 16:08:46 +0200
Message-Id: <1281017333-5563-12-git-send-email-u.kleine-koenig@pengutronix.de>
These two structs are referenced by cam60_spi_devices. The latter is
copied at init time to kmalloced memory and so the copy isn't freed after
booting. So it must not contain references to .init memory.
This isn't noticed by modpost as cam60_spi_devices is in .init.data, too.

cam60_spi_devices is passed to at91_add_device_spi which calls
spi_register_board_info. The latter makes a copy of it, so living in
.init.data is OK.
This fixes the following warning in cam60_defconfig:
WARNING: vmlinux.o(.data+0x2a00): Section mismatch in reference from the variable cam60_spi_devices to the (unknown reference) .init.data:(unknown)
The variable cam60_spi_devices references
the (unknown reference) __initdata (unknown)
If the reference is valid then annotate the
variable with __init* or __refdata (see linux/init.h) or name the variable:
*_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console,

Add support for the dedicated FIFO mode on newer SoCs such as the S5PV210
partly to improve support and to fix the bug where any non-EP0 IN endpoint
requires its own FIFO allocation.
To fix this, we ensure that any non-zero IN endpoint is given a TXFIFO
using the same allocation method as the periodic case (all our current
hardware has enough FIFOs and FIFO memory for a 1:1 mapping) and ensure
that the necessary transmission done interrupt is enabled.
The default settings from reset for the core point all EPs at FIFO0,
used for the control endpoint. However, the controller documentation
states that all IN endpoints _must_ have a unique FIFO to avoid any
contention during transmission.
Note, this leaves us with a large IN FIFO for EP0 (which re-uses the
old NPTXFIFO) for an endpoint which cannot shift more than a pair of
packets at a time... this is a waste, but it looks like we cannot
re-allocate space to the individual IN FIFOs as they are already
maxed out (to be confirmed).
