      [PATCH] ACPI patch 1/9 · 62c7aea9
      Andy Grover authored
      This is the first of 9 patches. We did a complete rewrite of the
      Linux-specific code, so we wait for things to stabilize before submitting.
      There will be more updates, but *much* smaller.
      
      #1 - this updates the header file.

      [PATCH] boot_cpu_data corruption on SMP x86 · 1ae90c54
      Mikael Pettersson authored
      The patch below eliminates a case of boot_cpu_data corruption
      on SMP x86 machines. This was first observed on SMP Athlons,
      but it also affects SMP Intel boxes in a less serious way.
      
      When the secondary processors boot and execute head.S:checkCPUtype,
      the code performs a 32-bit write of a small constant to the
      byte-sized variable boot_cpu_data.x86 (X86 in head.S). Since the
      write is 32-bit, it also writes zeros to the following 3 bytes,
      which clobbers the x86_vendor, x86_model, and x86_mask fields
      previously set up by check_bugs()'s call to identify_cpu().
      Thus, after smp_init(), boot_cpu_data will _always_ identify
      the CPU as an Intel (X86_VENDOR_INTEL == 0 in processor.h) with
      model 0 and stepping 0.
      
      The effect in standard kernels is not catastrophic, since:
      (a) most SMP x86 boxes are Intel
      (b) most uses of x86_vendor occur before smp_init() or reference
          the SMP cpu_data[] array
      (c) most post-boot references to boot_cpu_data occur in the
          cpu_has_XXX macros which only read the x86_capability[] array
      However, third-party extensions (like my x86 performance-monitoring
      conters driver) can get seriously confused by this mis-identification.

      [PATCH] Fix NR_IRQS when no IO apic · be5fc736
      Brian Gerst authored
      NR_IRQS should be 16 when the IO apic is not configured, as the 8259 PIC
      cannot generate any more interrupts.  It also fixes a bug where the IDT
      gets populated with random addresses, since only 16 entry stubs are
      created.

      [PATCH] Cleanup F00F bug code · a0816e18
      Brian Gerst authored
      This changes the F00F bug workaround code to use the fixmap facilities
      instead of touching the page tables directly.  It also removes the
      assumption that only 686's don't have the bug.  I have confirmation that
      the patch works on buggy pentiums.

      [PATCH] proc_pid_make_inode() fix · 11aec25f
      Alexander Viro authored
      	In case if proc_pid_make_inode() steps on exiting task we do
      iput() and return NULL.  Unfortunately, in that case inode->i_ino
      doesn't look like inumber of a per-process inode and we take the
      wrong path in proc_delete_inode().  I.e. do dput(PDE(inode)).  Which
      is left uninitialized...
      
      	We used to get out with that almost by accident - that code
      worked only because we had zeroed out one field of union and that
      guaranteed that another field would be NULL.  It worked, but broke
      at the first occasion.

      [PATCH] nfsd as filesystem · 063b009f
      Alexander Viro authored
      * introduces a new filesystem - nfsd.  No, it's not a typo.  It's a small
        tree with fixed topology defined by nfsd and IO on its files does what
        we used to do by hand in nfsctl.c.
      * turns sys_nfsservctl() into a sequence of open()/write()/read()/close()
        It works as it used to - we don't need nfsd to be mounted anywhere, etc.
      * nfsd_linkage ugliness is gone.
      * getfs and getfh demonstrate (rather trivial) example of "descriptor as
        transaction descriptor" behaviour.
      * we are fairly close to the situation when driver-defined filesystems can
        be done with practically zero code overhead.  We are still not there, but
        it's a matter of adding a couple of helpers for populating the tree.
      
      	One thing we get immediately is a cleanup of sys_nfsservctl() -
      it got _much_ better.  Moreover, we get an alternative interface that
      uses normal file IO and can be used without magic syscalls.

      [PATCH] fs/libfs.c · 5e689743
      Alexander Viro authored
      	Linus, I've taken a bunch of common methods into fs/libfs.c and
      killed the (duplicated) instances in filesystems.  There will be more -
      ideally I'd like to get a library that would make writing small filesystems
      trivial.

      [PATCH] 2.4 and 2.5: remove Alt-Sysrq-L · f9deb9e6
      Russell King authored
      The following patch removes Alt-Sysrq-L and its associated hack to kill
      of PID1, the init process.  This is a mis-feature.
      
      If PID1 is killed, the kernel immediately enters an infinite loop in the
      depths of do_exit() with interrupts disabled, completely locking the
      machine.  Obviously you can only reach for the reset button or power
      switch after this, leaving you with dirty filesystems.

      [PATCH] 2.5 and 2.4: fix PCI IO BAR flags · be4808e0
      Russell King authored
      There is a problem where the resource flags sometimes contain bits from
      the address part of the PCI BAR, especially when you have the low address
      bit set for an IO BAR.
      
      (bit 3 of a PCI IO BAR is an address bit, and (bar & 0xf) propagates this
      to res->flags).
      
      This exists in Ivan Kokshaysky PCI patches, and so far hasn't made it into
      the kernel.  It's required for IDE on certain ARM machines to even work.
