This patch moves all definitions of the PCI resource names to an 'enum',
and also replaces some hard-coded resource variables with symbol
names. This change eases introduction of device specific resources.Reviewed-by: Bjorn Helgaas

/proc/bus/pci allows you to mmap resource ranges too, so we should probably be
checking to make sure the mapping is somewhat valid. Uses the same code as the recent sysfs mmap range checking patch from Linus.Acked-by: David Miller

Fix wrong counter check for proc_dir_entry in pci_proc_detach_device().
The pci_proc_detach_device() returns with -EBUSY before calling
remove_proc_entry() if the reference counter of proc_dir_entry is not
0. But this check is wrong and pci_proc_detach_device() always fails
because the reference counter of proc_dir_entry is initialized with 1
at creating time and decremented in remove_proc_entry(). This bug
cause strange behaviour as followings:- Accessing /proc/bus/pci/XXXX/YY file after hot-removing pci adapter
card causes kernel panic.- Repeating hot-add/hot-remove of pci adapter card increases files
with the same name under /proc/bus/pci/XXXX/ directory. For example:# pwd
/proc/bus/pci/0002:09
# ls
01.0
# for i in `seq 5`
> do
> echo 0 > /sys/bus/pci/slots/0009_0032/power
> echo 1 > /sys/bus/pci/slots/0009_0032/power
> done
# ls
01.0 01.0 01.0 01.0 01.0 01.0The pci_proc_detach_device() should check if the reference counter is
not larger than 1 instead.Signed-off-by: Kenji Kaneshige

When a /proc/bus/pci file is written to, the size of that PCI device's
configuration space must be written to the inode. Otherwise, it is
possible for the file to specify a size of 0 on stat if a task is holding
the same file open.Signed-off-by: David Rientjes

On pci_proc_attach_device(), the size of the PCI configuration space is
stored in the proc_dir_entry as the size of the file. Thus, the procfs
interface to PCI devices should use it instead of the device directly.Signed-off-by: David Rientjes

Many struct file_operations in the kernel can be "const". Marking them const
moves these to the .rodata section, which avoids false sharing with potential
dirty data. In addition it'll catch accidental writes at compile time to
these shared resources.Signed-off-by: Arjan van de Ven

Some PCI adapters (eg. ipr scsi adapters) have an exposure today in that they
issue BIST to the adapter to reset the card. If, during the time it takes to
complete BIST, userspace attempts to access PCI config space, the host bus
bridge will master abort the access since the ipr adapter does not respond on
the PCI bus for a brief period of time when running BIST. On PPC64 hardware,
this master abort results in the host PCI bridge isolating that PCI device
from the rest of the system, making the device unusable until Linux is
rebooted. This patch is an attempt to close that exposure by introducing some
blocking code in the PCI code. When blocked, writes will be humored and reads
will return the cached value. Ben Herrenschmidt has also mentioned that he
plans to use this in PPC power management.Signed-off-by: Brian King

This is an updated version of Ben's fix-pci-mmap-on-ppc-and-ppc64.patch
which is in 2.6.12-rc4-mm1.It fixes the patch to work on PPC iSeries, removes some debug printks
at Ben's request, and incorporates your
fix-pci-mmap-on-ppc-and-ppc64-fix.patch also.Originally from Benjamin Herrenschmidt
This patch was discussed at length on linux-pci and so far, the last
iteration of it didn't raise any comment. It's effect is a nop on
architecture that don't define the new pci_resource_to_user() callback
anyway. It allows architecture like ppc who put weird things inside of
PCI resource structures to convert to some different value for user
visible ones. It also fixes mmap'ing of IO space on those archs.Signed-off-by: Benjamin Herrenschmidt

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.Let it rip!
