[PATCH 25/40] trace syscalls: Refactor syscall metadata creation
From: Ian Munsie <imunsie(a)au1.ibm.com> The syscall metadata creation macros are a bit convoluted with some duplicated code - particularly the duplication in SYSCALL_DEFINE0 with SYSCALL_METADATA and related macros. As demonstrated by the compat syscalls, there may be needs to introduce additional high level *_... 23 Jun 2010 06:14

[PATCH 38/40] trace syscalls: Remove redundant test for unmapped compat syscalls
From: Ian Munsie <imunsie(a)au1.ibm.com> Since the ftrace event initialisation routine now verifies that either the syscall number or the compat syscall number is valid and will not create events for unmapped syscalls, it is unnecessary to explicitly search for them, so remove it.

[PATCH 37/40] trace syscalls: Print out unmapped syscalls at boot
From: Ian Munsie <imunsie(a)au1.ibm.com> This patch will print out implemented but unmapped system calls at boot to help quickly identify remaining unmapped system calls.

[PATCH 34/40] trace syscalls: Convert generic syscalls without long return type
From: Ian Munsie <imunsie(a)au1.ibm.com> This patch converts a number of syscalls from the generic code that had return types other than long to use the new COMPAT_SYSCALL_DEFINEx_RET macros so their metadata is recorded for tracing.

[PATCH 36/40] trace syscalls: Early terminate search for sys_ni_syscall
From: Ian Munsie <imunsie(a)au1.ibm.com> Many system calls are unimplemented and mapped to sys_ni_syscall, but at boot ftrace would still search through every syscall metadata entry for a match which wouldn't be there. This patch adds causes the search to terminate early if the system call is not mapped. Sign... 23 Jun 2010 06:14

[PATCH 35/40] trace syscalls, PPC: Convert PPC syscalls without long return types
From: Ian Munsie <imunsie(a)au1.ibm.com> This patch converts the PowerPC system calls with return types other than long to use the various *SYSCALL_DEFINEx_RET family of macros so their metadata is recorded for tracing. This patch also renamed the ppc_rtas syscall to sys_rtas to fit in with the naming convention... 23 Jun 2010 06:14

[PATCH 01/40] ftrace syscalls: don't add events for unmapped syscalls
From: Ian Munsie <imunsie(a)au1.ibm.com> FTRACE_SYSCALLS would create events for each and every system call, even if it had failed to map the system call's name with it's number. This resulted in a number of events being created that would not behave as expected. This could happen, for example, on architectures ... 23 Jun 2010 06:14

linux-firmware tree vs. linux-firmware-from-kernel tree
Hello David, After switching from 'make firmware_install' to using the firmware files from the linux-firmware tree, I received a bug report about missing firmware files. While investigating, I noticed that the following commits are in linux-firmware-from-kernel, but not in linux-firmware: Ken Kawasaki (1): ... 23 Jun 2010 06:14
