This patch makes modpost able to process object files with more than
64k sections. Needed for huge kernel builds (allyesconfig, for example)
with -ffunction-sections. 64k sections handling is covered, for example,

It's the offset calculation in reloc_location() which overflows:
return (void *)elf->hdr + sechdrs[section].sh_offset +
(r->r_offset - sechdrs[section].sh_addr);E.g. for the first rodata r entry:
r->r_offset < sechdrs[section].sh_addr
and the expression in the parenthesis produces 0xFFFFFFE0 or something
equally wise.Reported-by: Alan

patch that moves the definitions to mod_devicetable.h. Verified that
aliases for these modules are generated correctly:drivers/media/radio/radio-sf16fmi.c

We don't use the normal hotplug mechanism because it doesn't work. It will
load the module some time after the device appears, but that's not good
enough for us -- we need the driver loaded _immediately_ because otherwise
the NIC driver may just abort and then the phy 'device' goes away.[bwh: s/phy/mdio/ in module alias, kerneldoc for struct mdio_device_id]

The sym_is() compares a symbol in an attempt to automatically skip symbol
prefixes. It does this first by searching the real symbol with the normal
unprefixed symbol. But then it uses the length of the original symbol to
check the end of the substring instead of the length of the symbol it is
looking for. On non-prefixed arches, this is effectively the same thing,
so there is no problem. On prefixed-arches, since this is exceeds by just
one byte, a crash is rare and it is usually a NUL byte anyways. But every
once in a blue moon, you get the right page alignment and it segfaults.For example, on the Blackfin arch, sym_is() will be called with the real
symbol "___mod_usb_device_table" as "symbol" when looking for the normal
symbol "__mod_usb_device_table" as "name". The substring will thus return
one byte into "symbol" and store it into "match". But then "match" will
be indexed with the length of "symbol" instead of "name" and so we will
exceed the storage. i.e. the code ends up doing:
char foo[] = "abc"; return foo[strlen(foo)+1] == '\0';Signed-off-by: Mike Frysinger

The next commit will require the use of MODULE_SYMBOL_PREFIX in
.tmp_exports-asm.S. Currently it is mixed in with C structure
definitions in "asm/module.h". Move the definition of this arch option
into Kconfig, so it can be easily accessed by any code.This also lets modpost.c use the same definition. Previously modpost
relied on a hardcoded list of architectures in mk_elfconfig.c.A build test for blackfin, one of the two MODULE_SYMBOL_PREFIX archs,
showed the generated code was unchanged. vmlinux was identical save
for build ids, and an apparently randomized suffix on a single "__key"
symbol in the kallsyms data).Signed-off-by: Alan Jenkins

This patch fixes a bug when incrementing/decrementing on a BCD formatted
integer (i.e. 0x09++ should be 0x10 not 0x0A). It just adds a function
for incrementing/decrementing BCD integers by converting to decimal,
doing the increment/decrement and then converting back to BCD.Signed-off-by: Nathaniel McCallum

The current code to generate usb modaliases from usb_device_id assumes
that the device's bcdDevice descriptor will actually be in BCD format.
While this should be a sane assumption, some devices don't follow spec
and just use plain old hex. This causes drivers for these devices to
generate invalid modalias lines which will never actually match for the
hardware.The following patch adds hex support for bcdDevice in file2alias.c by
detecting when a driver uses a hex formatted bcdDevice_(lo|hi) and
adjusts the output to hex format accordingly.Drivers for devices which have bcdDevice conforming to BCD will have no
change in modalias output. Drivers for devices which don't conform
(i.e. ibmcam) should now generate valid modaliases.EXAMPLE OUTPUT (ibmcam; space added to highlight change)

With this patch spi drivers can use standard spi_driver.id_table and
MODULE_DEVICE_TABLE() mechanisms to bind against the devices. Just like
we do with I2C drivers.This is useful when a single driver supports several variants of devices
but it is not possible to detect them in run-time (like non-JEDEC chips
probing in drivers/mtd/devices/m25p80.c), and when platform_data usage is
overkill.This patch also makes life a lot easier on OpenFirmware platforms, since
with OF we extensively use proper device IDs in modaliases.Signed-off-by: Anton Vorontsov

check of the flags in the sections.That check already ignored sections named ".comment" - but SUSE store
additional info in the comment section and has named it in a SUSE
