2008-04-28quota: quota core changes for quotaon on remountJan Kara5-22/+113
Currently, we just turn quotas off on remount of filesystem to read-only state. The patch below adds necessary framework so that we can turn quotas off on remount RO but we are able to automatically reenable them again when filesystem is remounted to RW state. All we need to do is to keep references to inodes of quota files when remounting RO and using these references to reenable quotas when remounting RW.

2008-04-28quota: various style cleanupsJan Kara4-28/+60
Cleanups in quota code: Change __inline__ to inline. Change some macros to inline functions. Remove vfs_quota_off_mount() macro. DQUOT_OFF() should be (0) is CONFIG_QUOTA is disabled. Move declaration of mark_dquot_dirty and dirty_dquot from quota.h to dquot.c [akpm@linux-foundation.org: coding-style fixes] Signed-off-by: Jan Kara <jack@suse.cz> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2008-04-28quota: remove superfluous DQUOT_OFF() in fs/namespace.cJan Kara1-2/+0
We don't need to turn quotas off before remounting root ro, because do_remount_sb() already handles this. Signed-off-by: Jan Kara <jack@suse.cz> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2008-04-28kprobes: prevent probing of preempt_schedule()Srinivasa Ds2-0/+59
Prohibit users from probing preempt_schedule(). One way of prohibiting the user from probing functions is by marking such functions with __kprobes. But this method doesn't work for those functions, which are already marked to different section like preempt_schedule() (belongs to __sched section). So we use blacklist approach to refuse user from probing these functions. In blacklist approach we populate the blacklisted function's starting address and its size in kprobe_blacklist structure. Then we verify the user specified address against start and end of the blacklisted function. So any attempt to register probe on blacklisted functions will be rejected.

2008-04-28spi: spi_imx updatesAndrea Paterniani1-109/+114
Updates to the i.MX SPI controller driver: 1) Some comments changed and/or added. 2) End of transfers is now managed on TXFIFO empty interrupt after the last write to TXFIFO. This speeds interrupt execution by removing the wait for TXFIFO to become empty. On TXFIFO empty interrupt the handler needs only to poll for the end of the ongoing transaction (SPI_CONTROL_XCH) to close the transfer. (2.1) Write only transfers are closed flushing RXFIFO. (2.2) Read transfers are closed reading trailing bytes from RXFIFO. (2.3) Read transfers where RXFIFO overrun occurred are closed by flushing RXFIFO and aborting the message. 3) Fifos are now flushed via SPI disable after the end of ongoing transaction.

Turn CONFIG_DMI into a selectable option if EMBEDDED is defined, in order to be able to remove the DMI table scanning code if it's not needed, and then reduce the kernel code size. With CONFIG_DMI (i.e before) : text data bss dec hex filename 1076076 128656 98304 1303036 13e1fc vmlinux Without CONFIG_DMI (i.e after) : text data bss dec hex filename 1068092 126308 98304 1292704 13b9a0 vmlinux Result: text data bss dec hex filename -7984 -2348 0 -10332 -285c vmlinux The new option appears in "Processor type and features", only when CONFIG_EMBEDDED is defined.

2008-04-28serial 8250: tighten test for using backup timerAlex Williamson1-2/+3
Thomas Koeller had reported an issue where a device that had been making use of the UART_BUG_TXEN code in the 8250 driver was mistakenly being caught by the backup timer test, causing the device to work improperly. To fix this, tighten the test requirements to enable the backup timer workaround. The backup timer is really meant to catch UARTs that don't re-assert the THRE interrupt. The expectation is that they do initially assert THRE. This patch clarifies the test.
