The only unfortunate bit here is that the name field of struct map_info
is not const, so for now we put a cast on the assignment of it.

To clearly state the intent of copying from linear sk_buffs, _offset being a
overly long variant but interesting for the sake of saving some bytes.
Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
So that it is also an offset from skb->head, reduces its size from 8 to 4 bytes
on 64bit architectures, allowing us to combine the 4 bytes hole left by the
layer headers conversion, reducing struct sk_buff size to 256 bytes, i.e. 4
64byte cachelines, and since the sk_buff slab cache is SLAB_HWCACHE_ALIGN...
:-)
Many calculations that previously required that skb->{transport,network,
mac}_header be first converted to a pointer now can be done directly, being
meaningful as offsets or pointers.

- Eliminate check for irq handler 'dev_id==NULL' where the
condition never occurs.
- Eliminate needless casts to/from void*
Signed-off-by: Jeff Garzik <jeff@garzik.org>
Maintain a per-CPU global "struct pt_regs *" variable which can be used instead
of passing regs around manually through all ~1800 interrupt handlers in the
Linux kernel.
The regs pointer is used in few places, but it potentially costs both stack
space and code to pass it around. On the FRV arch, removing the regs parameter
from all the genirq function results in a 20% speed up of the IRQ exit path
(ie: from leaving timer_interrupt() to leaving do_IRQ()).
Where appropriate, an arch may override the generic storage facility and do
something different with the variable. On FRV, for instance, the address is
maintained in GR28 at all times inside the kernel as part of general exception
handling.
Having looked over the code, it appears that the parameter may be handed down
through up to twenty or so layers of functions. Consider a USB character
device attached to a USB hub, attached to a USB controller that posts its
interrupts through a cascaded auxiliary interrupt controller. A character
device driver may want to pass regs to the sysrq handler through the input
layer which adds another few layers of parameter passing.
I've build this code with allyesconfig for x86_64 and i386. I've runtested the
main part of the code on FRV and i386, though I can't test most of the drivers.
I've also done partial conversion for powerpc and MIPS - these at least compile
with minimal configurations.
This will affect all archs. Mostly the changes should be relatively easy.
Take do_IRQ(), store the regs pointer at the beginning, saving the old one:
struct pt_regs *old_regs = set_irq_regs(regs);
And put the old one back at the end:
set_irq_regs(old_regs);
Don't pass regs through to generic_handle_irq() or __do_IRQ().
In timer_interrupt(), this sort of change will be necessary:
- update_process_times(user_mode(regs));
- profile_tick(CPU_PROFILING, regs);
+ update_process_times(user_mode(get_irq_regs()));
+ profile_tick(CPU_PROFILING);
I'd like to move update_process_times()'s use of get_irq_regs() into itself,
except that i386, alone of the archs, uses something other than user_mode().
Some notes on the interrupt handling in the drivers:
(*) input_dev() is now gone entirely. The regs pointer is no longer stored in
the input_dev struct.
(*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does
something different depending on whether it's been supplied with a regs
pointer or not.
(*) Various IRQ handler function pointers have been moved to type
irq_handler_t.

(cherry picked from 1b16e7ac850969f38b375e511e3fa2f474a33867 commit)
Add modalias attribute support for the almost forgotten now EISA bus and
(at least some) EISA-aware modules.
The modalias entry looks like (for an 3c509 NIC):
eisa:sTCM5093
and the in-module alias like:
eisa:sTCM5093*
The patch moves struct eisa_device_id declaration from include/linux/eisa.h
to include/linux/mod_devicetable.h (so that the former now #includes the
latter), adds proper MODULE_DEVICE_TABLE(eisa, ...) statements for all
drivers with EISA IDs I found (some drivers already have that DEVICE_TABLE
declared), and adds recognision of __mod_eisa_device_table to
scripts/mod/file2alias.c so that proper modules.alias will be generated.
There's no support for /lib/modules/$kver/modules.eisamap, as it's not used
by any existing tools, and because with in-kernel modalias mechanism those
maps are obsolete anyway.
The rationale for this patch is:
a) to make EISA bus to act as other busses with modalias
support, to unify driver loading
b) to foget about EISA finally - with this patch, kernel
(who still supports EISA) will be the only one who knows
how to choose the necessary drivers for this bus ;)

As I promised last week, here is the first pass at removing all
unnecessary printk's that exist in network device drivers currently in
promiscuous mode. The duplicate messages are not needed so they have
been removed. Some of these drivers are quite old and might not need an
update, but I did them all anyway.
I am currently auditing the remaining conditional printk's and will send
out a patch for those soon.

Becker-derived drivers often have the 'io_size' member in their chip
info struct, indicating the minimum required size of the I/O resource
(usually a PCI BAR). For many situations, this number is either
constant or irrelevant (due to pci_iomap convenience behavior).
This change removes the io_size invariant member, and replaces it with a
compile-time constant.
Drivers updated: fealnx, gt96100eth, winbond-840, yellowfin
Additionally,
- gt96100eth: unused 'drv_flags' removed from gt96100eth
- winbond-840: unused struct match_info removed
- winbond-840: mark pci_id_tbl[] const, __devinitdata

When in-kernel net drivers branched from Donald Becker's vanilla driver
set, in the days before BitKeeper and git, a driver changelog was
maintained in the driver source code. These days, the kernel's
changelog is far superior and much more accurate, so the in-driver
changelogs are removed.
Another relic of the Becker/kernel split was version numbering, using
"foo-LKx.y.z" notation, resulting in weird version numbers like
"1.17b-LK1.1.9". These drivers are for older hardware, and see few
changes these days, so the version numbers were all bumped to something
more simple.
Finally, in xircom_tulip_cb specifically, an additional cleanup removes
the always-enabled CARDBUS cpp macro.

Symbols such as PCI_USES_IO, PCI_ADDR0, etc. originated from Donald
Becker's net driver template, but have been long unused. Remove.
In a few drivers, this allows the further eliminate of the pci_flags (or
just plain flags) member in the template driver probe structure.
Most of this logic is simply open-coded in most drivers, since it never
changes.
Made a few other cleanups while I was in there, too:
* constify, __devinitdata several PCI ID tables
* replace table terminating entries such as "{0,}," and "{NULL},"
with a more-clean "{ }".
