[S390] pud_present/pmd_present bug.
Git commit
3610cce87af0693603db171d5b6f6735f5e3dc5b (yeah my own :-/)
introduced a bug in regard to pud/pmd table entries.
If the address of the page table refered to by a pud/pmd value happens
to have zeroes in the lower 32 bits, pud_present and pmd_present return
false. The obvious effect is that this triggers the BUG_ON in exit_mmap
because some ptes will not get released on process end. Worse is that
the next fault for memory covered by that pud/pmd will allocate another
pmd/pte table and populate the pud/pmd entry. The old page table
entries hanging below this entry are lost!
The fix is simple, properly check against 0. The check is added for
pud_none/pmd_none as well even if these two functions work because
the invalid bit is in the lower 32 bits.

This means slock-AF_AX25 could be taken both from softirq and process

ax25_list_lock vulnerable. It was not 100% verified if the real lockup

[NETFILTER]: bridge: fix missing link layer headers on outgoing routed packets
As reported by Damien Thebault, the double POSTROUTING hook invocation
fix caused outgoing packets routed between two bridges to appear without
a link-layer header. The reason for this is that we're skipping the
br_nf_post_routing hook for routed packets now and don't save the
original link layer header, but nevertheless tries to restore it on
output, causing corruption.
The root cause for this is that skb->nf_bridge has no clearly defined
lifetime and is used to indicate all kind of things, but that is
quite complicated to fix. For now simply don't touch these packets
and handle them like packets from any other device.

The __weak definition of plat_time_init was only ever meant to be a
migration helper to keep platforms that don't have a plat_time_init
compiling. A few greps says that all platforms now supply their own
plat_time_init() so the weak definition is no longer needed. So I
instead delete it.

[POWERPC] Make PS3_SYS_MANAGER default y, not m
Currently it's impossible to build a ps3_defconfig which will reboot
without modules installed. This makes it all too easy to find yourself
with a PS3 that won't reboot.
This is because the system manager driver, which provides the reboot
mechanism, is only selectable if PS3_ADVANCED is set, else it defaults
to m. In ps3_defconfig PS3_ADVANCED is not set, therefore the system
manager is built as a module.
It would be desirable IMHO for the defconfig to produce a kernel that
boots and reboots, without needing modules to be installed.

[POWERPC] Fix rounding bug in emulation for double float operating
This patch fixes rounding bug in emulation for double float operating on PowerPC platform.
When pack double float operand, it need to truncate the tail due to the limited precision.
If the truncated part is not zero, the last bit of work bit (totally 3 bits) need to '|' 1.
This patch is completed in _FP_FRAC_SRS_2(X,N,sz) (arch/powerpc/math-emu/op-2.h).
Originally the code leftwards rotates the operand to just keep the truncated part,
then check whether it is zero. However, the number it rotates is not correct when
N is not smaller than _FP_W_TYPE_SIZE, and it will cause the work bit '|' 1 in the improper case.
This patch fixes this issue.

the proper brightness support through ACPI video.c was loaded.
Therefore, remove the generation of these events by default, which is the
right thing for T60, X60, R60, T61, X61 and R61 with their latest BIOSes.
Distros that want to misuse these events into OSD reporting (which requires

[SERIAL] sparc: Infrastructure to fix section mismatch bugs.
This patch against 2.6.23 sparc-2.6.git contains a number of minor
cleanups of the sparc serial drivers. Initially I fixed this build
warning:
WARNING: vmlinux.o(.text+0x107a2c): Section mismatch: reference to .init.text:add_preferred_console (between 'sunserial_console_match' and 'sunserial_console_termios')
which is done by declaring sunserial_console_match() as __init. This
resulted in build warnings on sunserial_current_minor. To resolve
these the variable was changed so it is no longer global, and to hide
operations on it inside 2 new functions. These functions handle the
UART minor handling code that is common to all sparc serial drivers.
These changes allowed to clean up the uart counters in all the sparc
serial drivers, and the administration of minor device numbers.
Lastly, sunserial_console_termios() does not need to be exported since
it is only called from non-modular code.
Sadly, the following build warning still exists:
WARNING: vmlinux.o(__ksymtab+0x2910): Section mismatch: reference to .init.text:sunserial_console_match (between '__ksymtab_sunserial_console_match' and '__ksymtab_sunserial_unregister_minors')
This could be resolved by not exporting sunserial_console_match(), but
this is not possible at the moment because it is being called from
modular code. On the other hand, this is a bogus warning since it
comes from a ksymtab section.

[IPSEC]: Fix potential dst leak in xfrm_lookup
If we get an error during the actual policy lookup we don't free the
original dst while the caller expects us to always free the original
dst in case of error.
This patch fixes that.

[VLAN]: Fix potential race in vlan_cleanup_module vs vlan_ioctl_handler.
The vlan module cleanup function starts with
vlan_netlink_fini();
vlan_ioctl_set(NULL);
The first call removes all the vlan devices and
the second one closes the vlan ioctl.
AFAIS there's a tiny race window between these two
calls - after rtnl unregistered all the vlans, but
the ioctl handler isn't set to NULL yet, user can
manage to call this ioctl and create one vlan device,
and that this function will later BUG_ON seeing
non-emply hashes.
I think, that we must first close the vlan ioctl
and only after this remove all the vlans with the
vlan_netlink_fini() call.

[BNX2]: Fix RX packet rot.
Packets can be left in the RX ring if the NAPI budget is reached.
This is caused by storing the latest rx index at the beginning of
bnx2_rx_int(). We may not process all the work up to this index
if the budget is reached and so some packets in the RX ring may rot
when we later check for more work using this stored rx index.
The fix is to not store this latest hw index and only store the
processed rx index. We use a new function bnx2_get_hw_rx_cons()
to fetch the latest hw rx index.

[S390]: Fix use of skb after netif_rx
Recently, Wang Chen submitted a patch
(
d30f53aeb31d453a5230f526bea592af07944564) to move a call to netif_rx(skb)
after a subsequent reference to skb, because netif_rx may call kfree_skb on
its argument. netif_rx_ni calls netif_rx, so the same problem occurs in
the files below.
I have left the updating of dev->last_rx after the calls to netif_rx_ni
because it seems time dependent, but moved the other field updates before.
This was found using the following semantic match.
