This patch converts rcutorture's random-number generator from
get_random_bytes() (which has locking issues in some builds with patches)
to instead use local-to-rcutorture statistical counters. This involves
reading other CPUs' statistics, so the frequency of entropy addition
is simultaneously

With paravirt on, we cannot issue operations like swapgs, sysretq,
iretq, cli, sti. So they have to be changed into macros, that will
be later properly replaced for the paravirt case.
The sysretq is a little bit more complicated, and is replaced
by a sequence of three instructions. It is
This patch turns the set_p{te,md,ud,gd} functions into their

Also, it adds pte_update() and pte_update_defer() calls whenever
we modify a page table entry. This last part was coded to match
i386 as close as possible.

This patch switches the cli and sti instructions into macros.
In this header, they're just defined to the instructions they
refer to. Later on, when paravirt is defined, they will be
defined to something with paravirt abilities.

Hi,
until 2.6.21, I had the normal assignments for ttyS0 and ttyS1:
00:08: ttyS1 at I/O 0x2f8 (irq = 3) is a 16550A
00:09: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
With 2.6.22 I get the names <-> ports/irqs the other way around:
00:08: ttyS0 at I/O 0x2f8 (irq = 3) is a 16550A
00:09: ttyS1 at

on the PCI class (modem or serial). On certain softmodems (AC'97 modems)
this can lead to the recognition of non-existing serial ports.
