embedded: fix vc_translate operator precedence
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.

all reports confirm that it works, so this is an official post for

unless the Documentation directory is specifically set up to handle non

try harder to load tty ldisc driver
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.

mm/hugetlb: don't crash when HPAGE_SHIFT is 0
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

PNP: fix formatting of dbg_pnp_show_resources() output
Each resource should be printed on its own line, so start snprintf'ing
at the beginning of the buffer every time through the loop.
Also, use scnprintf() rather than snprintf() when building up the
buffer to print. scnprintf() returns the number of characters actually
written into the buffer (not including the trailing NULL).
snprintf() returns the number of characters that *would be* written,
assuming everything would fit in the buffer. That's nice if we want to
resize the buffer to make sure everything fits, but in this case, I
just want to keep from overflowing the buffer, and it's OK if the
output is truncated.
Using snprintf() meant that my "len" could grow to be more than the
the buffer size, which makes "sizeof(buf) - len" negative, which causes
this alarming WARN_ON:

tracehook: fix exit_signal=0 case
My commit
2b2a1ff64afbadac842bbc58c5166962cf4f7664 introduced a regression
(sorry about that) for the odd case of exit_signal=0 (e.g. clone_flags=0).
This is not a normal use, but it's used by a case in the glibc test suite.
Dying with exit_signal=0 sends no signal, but it's supposed to wake up a
parent's blocked wait*() calls (unlike the delayed_group_leader case).
This fixes tracehook_notify_death() and its caller to distinguish a
"signal 0" wakeup from the delayed_group_leader case (with no wakeup).

kernel/audit.c control character detection is off-by-one
Hello,
According to my understanding there is an off-by-one bug in the
function:
audit_string_contains_control()
in:
kernel/audit.c
Patch is included.
I do not know from how many places the function is called from, but for
example, SELinux Access Vector Cache tries to log untrusted filenames via
call path:
avc_audit()
audit_log_untrustedstring()
audit_log_n_untrustedstring()
audit_string_contains_control()
If audit_string_contains_control() detects control characters, then the
string is hex-encoded. But the hex=0x7f dec=127, DEL-character, is not
detected.
I guess this could have at least some minor security implications, since a
user can create a filename with 0x7f in it, causing logged filename to
possibly look different when someone reads it on the terminal.

[S390] Optimize storage key operations for anon pages
For anonymous pages without a swap cache backing the check in
page_remove_rmap for the physical dirty bit in page_remove_rmap is
unnecessary. The instructions that are used to check and reset the dirty
bit are expensive. Removing the check noticably speeds up process exit.
In addition the clearing of the dirty bit in __SetPageUptodate is
pointless as well. With these two changes there is no storage key
operation for an anonymous page anymore if it does not hit the swap
space.
The micro benchmark which repeatedly executes an empty shell script
gets about 5% faster.

[S390] nohz/sclp: disable timer on synchronous waits.
sclp_sync_wait wait synchronously for an sclp interrupt and disables
timer interrupts. However on the irq enter paths there is an extra
check if a timer interrupt would be due and calls the timer callback.
This would schedule softirqs in the wrong context.
So introduce local_tick_enable/disable which prevents this.

[S390] ipl: Reboot from alternate device does not work when booting from file
During startup we check if diag308 works using diag 308 subcode 6,

the system has been ipled from the HMC using load from CD or load from file.
In the case of rc = 0x102 we have to assume that diag 308 is working,

kgdb: fix gdb serial thread queries
The command "info threads" did not work correctly with kgdb. It would
result in a silent kernel hang if used.
This patach addresses several problems.
- Fix use of deprecated NR_CPUS
- Fix kgdb to not walk linearly through the pid space
- Correctly implement shadow pids
- Change the threads per query to a #define
- Fix kgdb_hex2long to work with negated values
The threads 0 and -1 are reserved to represent the current task. That
means that CPU 0 will start with a shadow thread id of -2, and CPU 1
will have a shadow thread id of -3, etc...
From the debugger you can switch to a shadow thread to see what one of
the other cpus was doing, however it is not possible to execute run
control operations on any other cpu execept the cpu executing the
kgdb_handle_exception().

kgdb: fix kgdb_validate_break_address to perform a mem write
A regression to the kgdb core was found in the case of using the
CONFIG_DEBUG_RODATA kernel option. When this option is on, a breakpoint
cannot be written into any readonly memory page. When an external
debugger requests a breakpoint to get set, the
kgdb_validate_break_address() was only checking to see if the address
to place the breakpoint was readable and lacked a write check.
This patch changes the validate routine to try reading (via the
breakpoint set request) and also to try immediately writing the break
point. If either fails, an error is correctly returned and the
debugger behaves correctly. Then an end user can make the
descision to use hardware breakpoints.
Also update the documentation to reflect that using
CONFIG_DEBUG_RODATA will inhibit the use of software breakpoints.

Fix rename of at91_nand -> atmel_nand
Structs called at91_nand_data where renamed to atmel_nand_data
and configs called *MTD_NAND_AT91* where renamed to
*MTD_NAND_ATMEL*. This was unfortunately not done consistently,
causing NAND chips not being initialised on several ARM boards.
I am aware that the author of the original change did not rename
MTD_NAND_AT91_BUSWIDTH to MTD_NAND_ATMEL_BUSWIDTH, for example.
All *MTD_NAND_AT91* where renamed to *MTD_NAND_ATMEL* in order
to keep naming consistency.
This patch was only tested on a MACH_SAM9_L9260, as this is the
only ARM board I have to my disposal.
Before this patch:
$ git-ls-files |xargs grep atmel_nand |wc -l

$ git-ls-files |xargs grep MTD_NAND_ATMEL |wc -l
