This reverts commit 2b14290078, since it
seems to break some other USB storage devices (at least a JMicron USB to
ATA bridge). As such, while it apparently fixes some cardreaders, it
would need to be made conditional on the exact reader it fixes in order
to avoid causing regressions.

No file should be explicitly referencing its own platform headers
by specifying an absolute include path. Fix these paths to use
standard <asm/arch/...> includes.

[MTD] Fix !CONFIG_BLOCK compile for mtdsuper.c
firmware: silence __fw_modbuild and __fw_modinst 'Nothing to be done' messages
Brian Wang reported that a FUSE filesystem exported through NFS could
return I/O errors on read. This was traced to splice_direct_to_actor()
returning a short or zero count when racing with page invalidation.
However this is not FUSE or NFSD specific, other filesystems (notably
NFS) also call invalidate_inode_pages2() to purge stale data from the
cache.
If this happens while such pages are sitting in a pipe buffer, then
splice(2) from the pipe can return zero, and read(2) from the pipe can
return ENODATA.
The zero return is especially bad, since it implies end-of-file or
disconnected pipe/socket, and is documented as such for splice. But
returning an error for read() is also nasty, when in fact there was no
error (data becoming stale is not an error).
The same problems can be triggered by "hole punching" with
madvise(MADV_REMOVE).
Fix this by not clearing the PG_uptodate flag on truncation and
invalidation.

As reported by Adrian Bunk, commit d5686b444f
(switch mtd and dm-table to lookup_bdev()) causes the following compile
error with CONFIG_BLOCK=n:
CC drivers/mtd/mtdsuper.o
drivers/mtd/mtdsuper.c: In function `get_sb_mtd':
drivers/mtd/mtdsuper.c:184: error: implicit declaration of function 'lookup_bdev'

drivers/mtd/mtdsuper.c:197: error: implicit declaration of function 'bdput'

Fix it by putting the block device lookup inside #ifdef CONFIG_BLOCK

People don't like them and think they're errors.
Leave the __fw_install one though; when 'make firmware_install' does
nothing, it's best to have a 'Nothing to be done for...' message rather
than just doing nothing.

This fixes a bug in operator precedence in the newly introduced vc_translate
macro. Without this fix, the translation of some characters on the
kernel console is garbled.
This patch was copied to the e-mail list previously for testing. Now,
all reports confirm that it works, so this is an official post for
application.

I asked legal about the licensing of ftrace.txt, and they told me that,
unless the Documentation directory is specifically set up to handle non
GPL licenses (which it does not appear to be), then it would be best to
put ftrace.txt under the GPL.
This patch adds a dual license to ftrace.txt such that it is under both
the FDL and the GPL.

Currently function tty_ldisc_get() tries to load an ldisc driver module
only when tty_ldisc_try_get() returns -EAGAIN. This happens only if
module is being unloaded. If ldisc module is not loaded
tty_ldisc_try_get() returns -EINVAL and this case is not handled in
tty_ldisc_get(), so request_module() is not called.
Attached patch fixes this by calling request_module() if
tty_ldisc_try_get() returned any error code.
I discovered this when my UMTS modem stopped working with 2.6.27-rc1
because module ppp_async was not loaded.

Some platform decide whether they support huge pages at boot time. On
these, such as powerpc, HPAGE_SHIFT is a variable, not a constant, and is
set to 0 when there is no such support.
The patches to introduce multiple huge pages support broke that causing
the kernel to crash at boot time on machines such as POWER3 which lack
support for multiple page sizes.

When defining a symbol in vmlinux.lds, use the VMLINUX_SYMBOL macro.
VMLINUX_SYMBOL adds a prefix charactor.
You can't just use straight symbol names in common header files as they
dont take into consideration weird arch-specific ABI conventions. in the
case of Blackfin/h8300, the ABI dictates that any C-visible symbols have
an underscore prefixed to them. Thus all symbols in vmlinux.lds.h need to
be wrapped in VMLINUX_SYMBOL() so that each arch can put hide this magic
in their own files.
