Subject: [PATCH 1/2] serial: Add flush_buffer() operation to uart_ops
Serial drivers using DMA (like the atmel_serial driver) tend to get very
confused when the xmit buffer is flushed and nobody told them. They
also tend to spew a lot of garbage since the DMA engine keeps running
after the buffer is flushed and possibly refilled with unrelated data.
This patch adds a new flush_buffer operation to the uart_ops struct,
along with a call to it from uart_flush_buffer() right after the xmit
buffer has been cleared. The driver can implement this in order to
syncronize its internal DMA state with the xmit buffer when the buffer
is flushed.

The configfs operations ->make_item() and ->make_group() currently

of this, -ENOMEM is the only return code bubbled up the stack.
Multiple folks have requested the ability to return specific error codes
when these operations fail. This patch adds that ability by changing the
->make_item/group() ops to return ERR_PTR() values. These errors are
bubbled up appropriately. NULL returns are changed to -ENOMEM for
compatibility.

fix dangling zombie when new parent ignores children
This fixes an arcane bug that we think was a regression introduced
by commit b2b2cbc4b2a2f389442549399a993a8306420baf. When a parent
ignores SIGCHLD (or uses SA_NOCLDWAIT), its children would self-reap
but they don't if it's using ptrace on them. When the parent thread
later exits and ceases to ptrace a child but leaves other live
threads in the parent's thread group, any zombie children are left
dangling. The fix makes them self-reap then, as they would have
done earlier if ptrace had not been in use.

commit still stands. The inconsistent treatment of children hidden by
ptrace was an unintended omission in the original change and in no way
invalidates its purpose.
This makes do_wait return the error returned by security_task_wait()
(usually -EACCES) in place of -ECHILD when there are some children the
caller would be able to wait for if not for the permission failure. A
permission error will give the user a clue to look for security policy
problems, rather than for mysterious wait bugs.

ptrace children revamp
ptrace no longer fiddles with the children/sibling links, and the
old ptrace_children list is gone. Now ptrace, whether of one's own
children or another's via PTRACE_ATTACH, just uses the new ptraced
list instead.
There should be no user-visible difference that matters. The only
change is the order in which do_wait() sees multiple stopped
children and stopped ptrace attachees. Since wait_task_stopped()
was changed earlier so it no longer reorders the children list, we
already know this won't cause any new problems.

In an ocfs2 cluster more than 1 node, run program mmap_truncate, which races
mmap writes and truncates from multiple processes. While the test is
running, a stat from another node forces writeout, causing an oops in
ocfs2_get_block() because it sees a buffer to write which isn't allocated.

Fix FADT parsing
The (1.0 inherited) separate length fields in the FADT are byte granular.
Further, PM1a/b may have distinct lengths and live in distinct address spaces.
acpi_tb_convert_fadt() should account for all of these conditions.
Apart from these changes I'm puzzled by the fact that, not just for
acpi_gbl_xpm1{a,b}_enable, acpi_hw_low_level_{read,write}() get an explicit
size passed rather than using the size found in the passed GAS. What happens
on a platform that defines PM1{a,b} wider than 16 bits? Of course,
acpi_hw_low_level_{read,write}() at present are entirely un-prepared to deal
with sizes other than 8, 16, or 32, not to speak of a non-zero bit_offset or
access_width...

PNPACPI: add support for HP vendor-specific CCSR descriptors
The HP CCSR descriptor describes MMIO address space that should appear
as a MEM resource. This patch adds support for parsing these descriptors
in the _CRS data.
The visible effect of this is that these MEM resources will appear
in /sys/devices/pnp0/.../resources, which means that "lspnp -v" will
report it, user applications can use this to locate device CSR space,
and kernel drivers can use the normal PNP resource accessors to
locate them.
