The AER error information printing support is implemented in
drivers/pci/pcie/aer/aer_print.c. So some string constants, functions
and macros definitions can be re-used without being exported.
The original PCIe AER error information printing function is not
re-used directly because the overall format is quite different. And
changing the original printing format may make some original users'
scripts broken.

When printing PCIe AER error information, each line is prefixed with
PCIe device and driver information. In original implementation, the
prefix is generated when each line is printed. In fact, all lines
share the same prefix. So this patch pre-generated the prefix, and
use that one when each line is printed.
In addition to common prefix can be pre-generated, the trailing white
spaces in string constants and NULLs in char * array constants can be
removed too. These can reduce the object file size further.
The size of object file before and after changing is as follow:
text data bss dec
before: 3038 0 0 3038
after: 2118 0 0 2118

APEI ERST firmware interface and implementation has no multiple users
in mind. For example, if there is four records in storage with ID: 1,
2, 3 and 4, if two ERST readers enumerate the records via
GET_NEXT_RECORD_ID as follow,
reader 1 reader 2
1
2
3
4
-1
-1
where -1 signals there is no more record ID.
Reader 1 has no chance to check record 2 and 4, while reader 2 has no
chance to check record 1 and 3. And any other GET_NEXT_RECORD_ID will
return -1, that is, other readers will has no chance to check any
record even they are not cleared by anyone.
This makes raw GET_NEXT_RECORD_ID not suitable for used by multiple
users.
To solve the issue, an in-memory ERST record ID cache is designed and
implemented. When enumerating record ID, the ID returned by
GET_NEXT_RECORD_ID is added into cache in addition to be returned to
caller. So other readers can check the cache to get all record ID
available.

This reverts commit c4ff4b829e.
Ted Ts'o reports:
"TPM is working for me so I can log into employer's network in 2.6.37.
It broke when I tried 2.6.38-rc6, with the following relevant lines
from my dmesg:
[ 11.081627] tpm_tis 00:0b: 1.2 TPM (device-id 0x0, rev-id 78)
[ 25.734114] tpm_tis 00:0b: Operation Timed out
[ 78.040949] tpm_tis 00:0b: Operation Timed out
This caused me to get suspicious, especially since the _other_ TPM
commit in 2.6.38 had already been reverted, so I tried reverting
commit c4ff4b829e: "TPM: Long default timeout fix". With this commit
reverted, my TPM on my Lenovo T410 is once again working."

Several ACPI drivers fail to build if CONFIG_NET is unset, because
they refer to things depending on CONFIG_THERMAL that in turn depends
on CONFIG_NET. However, CONFIG_THERMAL doesn't really need to depend
on CONFIG_NET, because the only part of it requiring CONFIG_NET is
the netlink interface in thermal_sys.c.
Put the netlink interface in thermal_sys.c under #ifdef CONFIG_NET
and remove the dependency of CONFIG_THERMAL on CONFIG_NET from
drivers/thermal/Kconfig.

A customer of ours, complained that when setting the reset

They noticed when only 4 bytes were set to 0 instead of 8,
everything worked correctly.
Mathew pointed out:

| We're supposed to be resetting trampoline_phys_low and
| trampoline_phys_high here, which are two 16-bit values.
| Writing 64 bits is definitely going to overwrite space
| that we're not supposed to be touching.

When the per cpu timer is marked CLOCK_EVT_FEAT_C3STOP, then we only
can switch into oneshot mode, when the backup broadcast device
supports oneshot mode as well. Otherwise we would try to switch the
broadcast device into an unsupported mode unconditionally. This went
unnoticed so far as the current available broadcast devices support
oneshot mode. Seth unearthed this problem while debugging and working
around an hpet related BIOS wreckage.
Add the necessary check to tick_is_oneshot_available().
