* x86: cpumask: x86 mmio-mod.c use cpumask_var_t for downed_cpusRusty Russell2009-03-18
| | | | | | | | | | | | | | | Impact: cleanup, reduce memory usage for CONFIG_CPUMASK_OFFSTACK=y Part of the "getting rid of obsolete cpumask_t" patch: 1) Use cpumask_var_t: this is a pointer if CONFIG_CPUMASK_OFFSTACK=y 2) Call alloc_cpumask_var() on first entry into enter_uniprocessor() 3) Use modern cpumask_* functions.

* x86: cpumask: update 32-bit APM not to mug current->cpus_allowedRusty Russell2009-03-18
| | | | | | | | | | | | | | | | Impact: cleanup, avoid cpumask games The APM code wants to run on CPU 0: we create an "on_cpu0" wrapper which uses work_on_cpu() if we're not already on cpu 0. This introduces a new failure mode: -ENOMEM, so we add an explicit err arg and handle Linux-style errnos in apm_err().

* x86: cpumask: use work_on_cpu in arch/x86/kernel/microcode_core.cRusty Russell2009-03-18
| | | | | | | | | | | | | | | | Impact: don't play with current's cpumask Straightforward indirection through work_on_cpu(). One change is that the error code from microcode_update_cpu() is now actually plumbed back to microcode_init_cpu(), so now we printk if it fails on cpu hotplug.

* cpumask: fix CONFIG_CPUMASK_OFFSTACK=y cpu hotunplug crashRusty Russell2009-03-18
| | | | | | | | | | | | | | | | | | | | | | Impact: Fix cpu offline when CONFIG_MAXSMP=y Changeset bc9b83dd1f66402b870301c3c7117b9c1484abb4 "cpumask: convert c1e_mask in arch/x86/kernel/process.c to cpumask_var_t" contained a bug: c1e_mask is manipulated even if C1E isn't detected (and hence not allocated). This is simply fixed by checking for NULL (which gcc optimizes out anyway of CONFIG_CPUMASK_OFFSTACK=n, since it knows ce1_mask can never be NULL). In addition, fix a leak where select_idle_routine re-allocates (and re-clears) c1e_mask on every cpu init.

| | | | | | | | | | | | | | | | | | | Impact: cleanup, potential bugfix Not sure what changed to expose this, but clearly that numa_node_id() doesn't belong in mmzone.h (the inline in gfp.h is probably overkill, too).

| * cpumask: remove x86 cpumask_t uses.Rusty Russell2009-03-13
| | | | | | | | | | | | | | | | | | | | | | | | | | Impact: cleanup We are removing cpumask_t in favour of struct cpumask: mainly as a marker of what code is now CONFIG_CPUMASK_OFFSTACK-safe.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Impact: cleanup (Thanks to Al Viro for reminding me of this, via Ingo) CPU_MASK_ALL is the (deprecated) "all bits set" cpumask, defined as so: #define CPU_MASK_ALL (cpumask_t) { { ... } } Taking the address of such a temporary is questionable at best, unfortunately 321a8e9d (cpumask: add CPU_MASK_ALL_PTR macro) added CPU_MASK_ALL_PTR: #define CPU_MASK_ALL_PTR (&CPU_MASK_ALL) Which formalizes this practice. One day gcc could bite us over this usage (though we seem to have gotten away with it so far). So replace everywhere which used &CPU_MASK_ALL or CPU_MASK_ALL_PTR with the modern "cpu_all_mask" (a real const struct cpumask *), and remove CPU_MASK_ALL_PTR altogether.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Guennadi Liakhovetski noticed that the end condition for the loop in bitmap_find_free_region() is wrong, and the "return if error" was also using the wrong conditional that would only trigger if the bitmap was an exact multiple of the allocation size, which is not necessarily the case with dma_alloc_from_coherent(). Such a failure would end up in bitmap_find_free_region() accessing beyond the end of the bitmap.

This is due to KERNELRELEASE being different when the initial make is run and when make is run from rpmbuild. mkspec creates kernel.spec using KERNELRELEASE: <mkspec> echo "%files" echo '%defattr (-, root, root)' echo "%dir /lib/modules" echo "/lib/modules/$KERNELRELEASE" echo "/lib/firmware" echo "/boot/*" echo "" </mkspec> When CONFIG_LOCALVERSION_AUTO=y scripts/setlocalversion is called and grabs any additional version info from SCM. Next, the srctree is tarred up and SCM information is excluded. rpmbuild reruns make and in the process generates a new include/config/kernel.release and thus a new KERNELRELEASE. However this time the SCM information is gone so KERNELRELEASE no longer has the additional version information. When "make modules_install" runs, it uses the new KERNELRELEASE value to determine where to install the modules. This conflicts with where the spec file assumes they are going because of the mis-matching KERNELRELEASE versions. <snippet> + INSTALL_MOD_PATH=/var/tmp/kernel-2.6.29rc4tip01479g5d85422-root + make -j16 modules_install INSTALL crypto/aead.ko INSTALL crypto/cbc.ko INSTALL crypto/chainiv.ko INSTALL crypto/crc32c.ko INSTALL crypto/crypto_algapi.ko INSTALL crypto/crypto_blkcipher.ko INSTALL crypto/crypto_hash.ko INSTALL crypto/cryptomgr.ko INSTALL crypto/ecb.ko INSTALL crypto/eseqiv.ko INSTALL crypto/krng.ko INSTALL crypto/md5.ko INSTALL crypto/pcbc.ko INSTALL crypto/rng.ko INSTALL drivers/block/cciss.ko INSTALL drivers/hid/hid-dummy.ko INSTALL drivers/scsi/iscsi_tcp.ko INSTALL drivers/scsi/libiscsi.ko INSTALL drivers/scsi/libiscsi_tcp.ko INSTALL drivers/scsi/scsi_transport_iscsi.ko INSTALL drivers/scsi/scsi_wait_scan.ko INSTALL fs/lockd/lockd.ko INSTALL fs/nfs/nfs.ko INSTALL fs/nfsd/nfsd.ko INSTALL lib/libcrc32c.ko INSTALL net/sunrpc/sunrpc.ko DEPMOD 2.6.29-rc4-tip + cp arch/x86/boot/bzImage /var/tmp/kernel-2.6.29rc4tip01479g5d85422-root/boot/vmlinuz-2.6.29-rc4-tip-01479-g5d85422 + cp System.map /var/tmp/kernel-2.6.29rc4tip01479g5d85422-root/boot/System.map-2.6.29-rc4-tip-01479-g5d85422 + cp .config /var/tmp/kernel-2.6.29rc4tip01479g5d85422-root/boot/config-2.6.29-rc4-tip-01479-g5d85422 + cp vmlinux vmlinux.orig + bzip2 -9 vmlinux + mv vmlinux.bz2 /var/tmp/kernel-2.6.29rc4tip01479g5d85422-root/boot/vmlinux-2.6.29-rc4-tip-01479-g5d85422.bz2 + mv vmlinux.orig vmlinux + /usr/lib/rpm/brp-compress Processing files: kernel-2.6.29rc4tip01479g5d85422-2 error: File not found: /var/tmp/kernel-2.6.29rc4tip01479g5d85422-root/lib/modules/2.6.29-rc4-tip-01479-g5d85422 RPM build errors: File not found: /var/tmp/kernel-2.6.29rc4tip01479g5d85422-root/lib/modules/2.6.29-rc4-tip-01479-g5d85422 make[1]: *** [rpm] Error 1 make: *** [rpm] Error 2 </snippet> I have tested this patch on git -tip, Linus' git tree, and the kernel.org tar files, both with and without CONFIG_LOCALVERSION_AUTO=y.

This check triggered if zlib_inflate asked to be called again (Z_OK) with avail_out == 0 and no more output buffers available. This check proves to be rather dumb, as it incorrectly catches the case where zlib has generated all the output, but there are still input bytes to be processed. This patch does a number of things. It removes the original check and replaces it with code to not move to the next output buffer if there are no more output buffers available, relying on zlib to error if it wants an extra output buffer in the case of data corruption. It also replaces the Z_NO_FLUSH flag with the more correct Z_SYNC_FLUSH flag, and makes the error messages more understandable to non-technical users.

The call doesn't hurt anything and wastes only a couple of cycles. The reason to fix it is because this module serves as an example to hackers writing new hwmon drivers, and this part of the example is confusing.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The it87 driver is reporting -128 degrees C as +128 degrees C. That's not a terribly likely temperature value but let's still get it right, especially when it simplifies the code. Signed-off-by: Jean Delvare <khali@linux-fr.org>
