The first two hunks of the patch really belongs in patch 1, but I missed them on the first pass and instead of redoing all 3 patches I stuck them in this one. Signed-off-by:

Removes a few pointless register keywords. register is merely a compiler hint that access to the variable should be optimized, but gcc (3.3.6 in my case) generates the exact same code with and without the keyword, and even if gcc did something different with register present I think it is doubtful we would want to optimize access to these variables - especially since this is generic library code and there are supposed to be optimized versions in asm/ for anything that really matters speed wise. (akpm: iirc, keyword register is a gcc no-op unless using -O0) Signed-off-by:

The only call to ide_cdrom_capacity is in code protected by CONFIG_PROC_FS, so when that is not enabled, the compiler complains: drivers/ide/ide-cd.c:3259: warning: `ide_cdrom_capacity' defined but not used Here is a patch that fixes that. It provides some space savings for embedded systems that are not using procfs, as well: text data bss dec hex filename - 33540 6504 1032 41076 a074 drivers/ide/ide-cd.o + 33468 6480 1032 40980 a014 drivers/ide/ide-cd.o Signed-off-by:Amos Waterland <apw@us.ibm.com> Cc: Jens Axboe <axboe@suse.de> Cc: Bartlomiej Zolnierkiewicz <B.Zolnierkiewicz@elka.pw.edu.pl> Signed-off-by:

task_struct is an internal structure to the kernel with a lot of good information, that is probably interesting in core dumps. However there is no way for user space to know what format that information is in making it useless. I grepped the GDB 6.3 source code and NT_TASKSTRUCT while defined is not used anywhere else. So I would be surprised if anyone notices it is missing. In addition exporting kernel pointers to all the interesting kernel data structures sounds like the very definition of an information leak. I haven't a clue what someone with evil intentions could do with that information, but in any attack against the kernel it looks like this is the perfect tool for aiming that attack. So since NT_TASKSTRUCT is useless as currently defined and is potentially dangerous, let's just not export it. (akpm: Daniel Jacobowitz <dan@debian.org> "would be amazed" if anything was using NT_TASKSTRUCT). Signed-off-by:

Remove timer_list.magic and associated debugging code. I originally added this when a spinlock was added to timer_list - this meant that an all-zeroes timer became illegal and init_timer() was required. That spinlock isn't even there any more, although timer.base must now be initialised. I'll keep this debugging code in -mm. Signed-off-by:

This patch makes the workqueus use alloc_percpu instead of an array. The workqueues are placed on nodes local to each processor. The workqueue structure can grow to a significant size on a system with lots of processors if this patch is not applied. 64 bit architectures with all debugging features enabled and configured for 512 processors will not be able to boot without this patch.

-
john stultz authored
Create a macro shift_right() that avoids the numerous ugly conditionals in the NTP code that look like: if(a < 0) b = -(-a >> shift); else b = a >> shift; Replacing it with: b = shift_right(a, shift); This should have zero effect on the logic, however it should probably have a bit of testing just to be sure. Also replace open-coded min/max with the macros. Signed-off-by : John Stultz <johnstul@us.ibm.com> Signed-off-by: -

TIOCSTART and TIOCSTOP are defined in asm/ioctls.h and asm/termios.h by various architectures but not actually implemented anywhere but in the IRIX compatibility layer, so remove their COMPATIBLE_IOCTL from parisc, ppc64 and sparc64. Move the TIOCSLTC COMPATIBLE_IOCTL to common code, guided by an ifdef to only show up on architectures that support it (same as the code handling it in tty_ioctl.c), aswell as it's brother TIOCGLTC that wasn't handled so far.

We're trying to get rid of as much as possible tasklist walks, or at least moving them to core code. This patch falls into the second category. Instead of walking the tasklist in cfq-iosched move that into elv_unregister. The added benefit is that with this change the as ioscheduler might be might unloadable more easily aswell. The new code uses read_lock instead of read_lock_irq because the tasklist_lock only needs irq disabling for writers. Signed-off-by:

Fix the problem (BUG 4964) with unmapped buffers in transaction's t_sync_data list. The problem is we need to call filesystem's own invalidatepage() from block_write_full_page(). block_write_full_page() must call filesystem's invalidatepage(). Otherwise following nasty race can happen: proc 1 proc 2 ------ ------ - write some new data to 'offset' => bh gets to the transactions data list - starts truncate => i_size set to new size - mpage_writepages() - ext3_ordered_writepage() to 'offset' - block_write_full_page() - page->index > end_index+1 - block_invalidatepage() - discard_buffer() - clear_buffer_mapped() - commit triggers and finds unmapped buffer - BOOM!

I just noted that -mtune is used, which is only supported on recent GCCs; by reading http://gcc.gnu.org/gcc-3.4/changes.html, you see "-mcpu has been renamed to -mtune.", so for GCC < 3.4 we're not using any specific tuning in the appropriate cases. However -mcpu is deprecated, so use -mtune when possible. This was introduced by commit e9d4dce954a60dc23dd1d967766ca2347b780e54 of the old tree (between 2.6.10-rc3 and 2.6.10) by Linus Torvalds, to remove the use of -march, since that could trigger gcc using SSE on its own. But no attention was used about using -mcpu vs. -mtune. And btw, the old 2.6.4 code (for instance) was: cflags-$(CONFIG_MPENTIUMII) += $(call check_gcc,-march=pentium2,-march=i686) cflags-$(CONFIG_MPENTIUMIII) += $(call check_gcc,-march=pentium3,-march=i686) cflags-$(CONFIG_MPENTIUMM) += $(call check_gcc,-march=pentium3,-march=i686) cflags-$(CONFIG_MPENTIUM4) += $(call check_gcc,-march=pentium4,-march=i686) Signed-off-by:

This was used in the old dark age of 2.4, ARCH_CFLAGS doesn't work any more since some time, and UM_FASTCALL was never used in 2.6. Instead, reintroduce the thing more properly now, directly in include/asm-um/linkage.h. Signed-off-by:

Remove RWSEM_GENERIC_SPINLOCK, it's now defined (only if needed) by the underlying arch/i386/Kconfig.cpu. Leave it only for x86_64. Even there, it's totally wrong, as they even have the code to support XCHG_ADD. Signed-off-by:
-
Paolo 'Blaisorblade' Giarrusso authored
Make UML share the underlying cpu-specific tuning done on i386. Actually, for now many config options aren't used a lot - but that can be done later. Also, UML relies on GCC optimization for things like memcpy and such more than i386, so specifying the correct -march and -mtune should be enough. Later, we may want to correct some other stuff. For instance, since FPU context switching, for us, is done (at least partially, i.e. between our kernelspace and userspace) by the host, we may allow usage of FPU operations by GCC. This doesn't hold for kernelspace vs. kernelspace, but we don't support preemption. Signed-off-by:
